Alliance Environmental, LLC Sustainable Wastewater Treatment Infrastructure: Engineering Concept Report

October 22, 2010

Executive Summary

Schuyler County is a vibrant community of small towns and villages supported by a burgeoning agricultural, winery and tourist industry. Opportunities for further economic development rely on the expansion of wastewater infrastructure. As part of wider sustainability objectives this report has explored the potential to meet wastewater treatment needs with innovative ecological solutions such as natural systems. It was found that current wastewater capacity is substandard for supporting future growth. The Villages of Odessa and Burdett, and parts of the Village of Montour Falls, suffer problems with failing septic systems. The Watkins Glen wastewater treatment plant is forced to capacity during race days at the Watkins Glen International Speedway. The wastewater treatment plant at Montour Falls is susceptible to inflow and infiltration during wet weather events which cause overflow. To properly understand the needs of the community research has included a review of previous studies into Schuyler County sewer services, an appraisal of the current situation via site visits, and the outcomes of an interactive public workshop where community members expressed their priorities regarding the service that wastewater infrastructure would provide to the community. A specification for concept proposal was developed from research, and it was believed that this is well answered by using a network of constructed wetlands to provide wastewater treatment solutions. The proposed decentralized network of natural systems for Watkins Glen, Montour Falls, Odessa, Burdett and the un-serviced regions of Montour Falls has an estimated capital requirement of $24.1 million, which can be invested in phases, and will provide 901,000 gpd of wastewater treatment capacity to the region. Considering capital and operational expense, the 50-year cost of life-cycle and carbon footprint for the network have been estimated as $44 million and 5400 T CO2. This represents a savings on expenditure of 25% and a savings on CO2 emissions of 85% in comparison to an alternative centralized activated sludge system. We believe that further opportunities for sustainable wastewater infrastructure in the community include wastewater solids management, winery wastewater management, landfill leachate treatment, and stormwater management. These opportunities require further investigation in conjunction with SCOPED, but they could be developed in tandem with the proposed municipal wastewater network.

Introduction

Schuyler County has a population of approximately 19,000 1 across an area 219,000 acres. The county is composed of small town communities including four villages which are the subject of this study (approximate 2009 populations in brackets): Burdett (331), Montour Falls (1,747), Odessa (575) and Watkins Glen (1,989). Major economic drivers in the area include (with recent $USD cash sales in brackets) agriculture ($35.4 million, 2008), tourism ($26.4 million, 2008)2 and wine production ($11.9 million, 2003). This contribution is provided by approximately 400 farms totaling approximately 98,000 acres in agriculture (64,000 acres currently farmed), and 22 wineries which are located throughout the Seneca Lake Region. Other economic influences in the County include two large-scale salt processing plants (US Salt and Cargill) and 3lumber processing (Wagner Lumber). Through a Comprehensive Plan, Schuyler County has identified that community sustainability and economic development in the region must focus on the area's unique assets. With a solid tourism base, several well-established industries and a spectacular environment, economic development in Schuyler County can break away from the traditional "business retention and expansion" models and embrace flexible, creative and sustainable programs3. Development of eco-tourism and agri-tourism markets has been identified as a way of protecting agricultural lands and maintaining the unique character of these small communities. However, the existing infrastructure, such as wastewater, must be upgraded and expanded to support desired economic development. The limitations imposed by present wastewater infrastructure include: · · · · An under-sized wastewater treatment plant at Montour Falls which has reported compliance issues. Failing septic systems in the smaller towns of Odessa and Burdett, creating groundwater contamination issues and limits their opportunity for growth Recent expansions of the service provided by the Watkins Glen treatment plant hasl put the existing infrastructure under stress There are no longer any local facilities for septage or bio-solids disposal, or winery wastewater disposal. The costs of haulage and regulated disposal are prohibiting future development of the region

An improved solution must enable short-term development while ensuring long-term resource protection of the natural resources that are instrumental to Schuyler County's development plans. Resultantly, the Schuyler County Green Infrastructure Strategy seeks innovative, ecological solutions to existing infrastructure problems, which align with wider sustainability objectives. The scope of this report is to recommend a program to implement sustainable wastewater infrastructure. The developed program will consider: · Improvements to existing infrastructure at Burdett, Odessa, Montour Falls and Watkins Glen. · Strategies to add capacity to accommodate expansion plans for community size, tourism industry, associated industrial wastewater production from wineries · Wastewater solids management within the region to improve the affordability of disposal for septage, treatment plant sludges and winery bio-solids · Opportunities to integrate with or benefit the agricultural and salt processing industries The study will be completed in several sections. In Section 2 we analyze existing infrastructure and consider previous recommendations for improvement. In Section 3 we report on the findings of a community stakeholder public workshop, which is used to develop an alternative solution to best fit the needs of the community. In Section 4 we consider the appropriateness of various wastewater treatment technologies for the community, goals of the study, and potential locations for construction. This will be done by considering technologies with regard to: a. Land availability and value for other uses of suggested sites b. Capital Expenditure and Operational Expenditure (cost of life cycle) c. County/state discharge restriction for ground and surface waters d. Ability to meet compliance, and environmental protection goals beyond compliance e. Potential for water reuse f. Potential for nutrient and energy capture g. The carbon footprint associated with operation h. Suitability of soil geology, topography at suggested sites In Section 5 we propose several conceptual scenarios which would be most appropriate, and offer different benefits to each community, and discuss the costs of these strategies in more detail. In Section 6 we discuss funding mechanisms to implement the proposed solutions.

Section 2.0

Background

The first part of this Section will develop a water balance for the region based on current and projected activities throughout the County. This will include wine and tourist industry contributions. Secondly, scrutiny will be given to existing wastewater facilities for each town and for the management of wastewater solids and winery wastewater. Discussion will include current permit requirements and how these support environmental preservation goals, and barriers to growth. Thirdly, the pros and cons of previous suggestions for wastewater infrastructure will be considered, including cost and energy requirements. Previously suggested conventional solutions will inform a baseline case and will allow for benchmarking against alternative solutions.

2.1

Water Consumption and Wastewater Production in Schuyler County

The following passage is adapted from Hicks (2010) 4. Of the four incorporated villages in Schuyler County, only two have public sewer systems. Public sewer is available for the Village of Montour Falls and the Village of Watkins Glen. An extension of the Watkins Glen district encompasses a small section of the Town of Reading (directly along the Seneca Lake shoreline approximately one (1) mile heading northwest out of the village), and southwest into the Town of Dix another three (3) miles to service Watkins Glen International, the Empire Business Zone and the 69 single-family homes in Dix. The remaining portion of the county, about 75% of residents or 7,359 households, rely on wastewater treatment systems (WTS or septic systems) for disposal and treatment of their residential wastewater. Wineries are not serviced by public sewers and either have onsite wastewater treatment facilities or haul winery wastewater off-site for treatment. All four villages, as well as large areas in the Town of Hector, have public water available. However, public water is only available to less than half of county residents, leaving about 6,323 households with individual water supplies (IWS). Wineries generally obtain water via private wells, and the salt industry draws water directly from Seneca Lake. Regarding the water balance for Schuyler County; weather records indicate that an average of 2.9 inches of precipitation per month (0.1 inches per day) falls on the Watkins Glen region,

with a standard deviation of approximately 0.6 inches per month. Approximately 98% of the county is undeveloped, which means that approximately 79,661,250 gpd recharge groundwater and surface water supplies. Table 1 indicates residential water demands in the region using information adapted from the Hunt Engineers Infrastructure Development report published in 2003. From Table 1 it can be seen that the average total residential water demand for the region in 2003 was 2,073,000 gpd, which also includes information for the larger towns in Schuyler County who obtain water via private wells. By 2030 it is assumed that average daily demand in the region will increased to 308,000 gpd. It is assumed that groundwater supplies are plentiful enough that projected increase in demand in the larger towns by 2030 will be obtainable using wells. For the villages with municipal water supply it is projected that current water supply capacity will be sufficient for providing average daily demand by 2030; however, the Villages of Montour Falls and Watkins Glen may struggle to meet peak demand. This is particularly so for Watkins Glen which has to provide approximately 410,000 gpd of water to Watkins Glen International on race days, which is approximately 25% of current capacity. We feel it is important to emphasize these projections although exploring concepts for sustainable water supply are beyond the scope of this report.

Winery water demands are based on a water footprint for wine production of 3:1 and 36 wineries on the Seneca Lake Wine Trail producing 750,000 gpy5, adjusted for 22 wineries in Schuyler County. Total daily water demand from the winery industry is expected to be in the region of 7,640 gpd, occurring across a six-month season of pressing and retail. Based on a projected economic sector growth which accommodates one new average winery every 2 years, it is expected that winery demand will increase to 11,100 gpd by 2030. Eco-tourism and agri-tourism in the region may also create a water demand additional to residential requirements. To illustrate the potential demand created during tourist season: it is assumed that the number of tourists using Schuyler County as a base is proportional to the number of Seneca Lake wineries located in Schuyler County (approx. 40%). The number of visitors to the Seneca Lake Wine Trail in 2003 was 1,294,000. If 1/3rd of the visitors stay in the area for an average of 2 days and contribute to wastewater production equivalent to domestic flows, then an additional water demand of approximately 286,000 gpd could be created; which is equivalent to an additional large village. By the same assumptions, if the tourism numbers increase at historic rates then by 2030 the additional water demand created by tourists may be as high as 570,000 gpd during peak season. If tourists mainly impose water demand at wineries and boutique farms then it is possible that on-site wells could be expanded to cope with increased demand. If hotel, dining and leisure facilities expand in the Villages as a result of increasing tourism then increased demand on Village water supply will need considering. The exact water demands of the salt industry are unclear, although it is expected that they comprise a major demand on water resources withdrawn directly from Seneca Lake. Using some of the previous calculations, Table 2 details wastewater production calculations for the four incorporated villages in Schuyler County and estimated seasonal contributions from the winery, racing and tourism industries. Two sets of figures are given based on calculations of the current situation in 2009, and projections of the water balance for 2030 based on proposed economic development plans. As of 2009, it is estimated that on a peak day (race day plus eco-tourism and agri-tourism season) the wastewater treatment capacity required is on the order of 1 million gallons per day (mgd). It is estimated that the required capacity will increase by 50% due to a regional population increase of 5,000 people over the

Assumptions: Single person wastewater loadings and constituents are as per US EPA (2002). Winery wastewater concentrations are as per Masi (2002) Storm-water component of combined wastewater flow is not included in these calculations Population growth projection is based on 2% increase year on year Winery wastewater flows are based on waste:product volume of 3:1 and 36 wineries on the Seneca Lake Wine Trail producing 750,000 gpy, adjusted for 22 wineries in Schuyler County. It is assumed winery wastewater production is spread across six months. Increase in winery numbers is based on average 1 new winery every 2 years over the past 10 years. WGI is Watkins Glen International Speedway, which reportedly produces 410,000 gpd of wastewater on race days but limits this to maximum 300,000 gpd discharge. It is assumed that wastewater is one third the strength of residential wastewater Tourism is based on 1,294,000 visitors to Seneca Lake Wine Trail in 2003. As approximately 40% of wine trail wineries are in Schuyler County, the number of total tourists is apportioned. It is assumed 1/3rd stay in the area and contribute to wastewater production at hotels and restaurants, equivalent to domestic flows. Average visitor stay is taken as 2 days Increase in tourism is based on roughly linear increase of 70,000 tourists per year over the past 18 years. It is understood that salt processing plants may treat their own wastewater. More information would be required for design purposes

next 20 years, plus a doubling in the number of visitors to the area with an associated increase in the number of wineries. Regarding stormwater flows in the combined sewer systems of Montour Falls and Watkins Glen: it is known that about 3,000 acres of Schuyler County is developed. 6 Assuming that the four incorporated villages comprise 50% of the total developed area, and using a run-off coefficient of 0.75, an additional average stormwater flow-rate of 409,210 gpd can be estimated.

2.2

Current Wastewater Treatment Situation

This section will summarize the existing facilities in each sector and discuss their current ability to deal with current wastewater requirements and limitations with regard to accommodating projected growth. 2.2.1 Village of Watkins Glen Watkins Glen with approximately 2,000 residents is located on the southern shore of Seneca Lake and surrounded by the Town of Dix. The Village has experienced a decrease in population over the past 20 years, yet it remains a draw for visitors who travel to local attractions in the area, such as the races at the Watkins Glen International Speedway. Watkins Glen's wastewater treatment facility was constructed in 1962 and is on the Southern shore of Seneca Lake (occupying prime lake-front property). The existing wastewater treatment plant is located on two parcels (65.09-2-38.2 and 65.09-2-39.1) that together make up 1.25 acres. The plant services the Village of Watkins Glen and portions of the Town of Reading, including the Salt Point Road area. Recent construction activities extended service to the Empire Zone Business Park and the Watkins Glen International Speedway in the Town of Dix, with additional service to 69 single-family homes. The plant uses an activated sludge treatment process and is constructed to produce secondary level treated effluent.

Permitted effluent limits are as follows: Flow (30-day avge) 0.7 mgd TSS (7-day avge) 45 mg/l TSS (30-day avge) 30 mg/l TSS Removal 85% min BOD (7-day avge) 45 mg/l BOD (30-day avge) 30 mg/l BOD Removal 85% min UOD 85 mg/l The existing WWTP has a current capacity of 0.7 mgd, in line with permit. Daily flows from the Watkins Glen/Reading area have historically been less than 0.4mgd, however, race day activities at WGI Speedway are expected to create an additional 0.3 mgd which will strain the capacity of the plant and create potential compliance issues. Only a dozen or so properties in Watkins Glen are not serviced by the public sewer. Concerns have been raised over the facility's location on prime real estate on the lake shore, particularly with neighbors such as the Harbor Glen Hotel, marina and the municipal beach. The land on which the WWTP is presently situated has been assessed in 2010 at a value of $1,150,000. 7 Odor is sometimes an issue and with highquality, highly visible uses located nearby. As presently configured, the location of the treatment plant diminishes economic opportunities for improved land uses along the lakefront in the Village and it raises quality of life concerns for adjoining neighbors. 2.2.2 Village of Montour Falls The Village of Montour Falls is located within the Town of Montour and consists of approximately 1,750 residents. Like Watkins Glen, Montour Falls has numerous aesthetic qualities that make it a destination point for travelers and sight-seeing. However, lack of adequate wastewater collection and treatment impinges on its ability to enhance those features and grow. The Montour Falls wastewater treatment plant is located at the northerly end of the village and discharges to Catharine Creek. The treatment facility was built in 1962 and

is located on three small parcels (76.19-2-5, 76.19-2-83, and 76.19-2-6) totaling approximately 7.1 acres with land assessed at $41,400. The sewer system comprises four (4) village pump systems and a pipe network that was largely upgraded from vitrified clay to PVD and HDPE in 2001. The treatment train includes a Fixed Activated Sludge Treatment (FAST)system (Smith and Loveless, Inc.) and a tricking filter. The treatment plant is designed to produce secondary level effluent quality. Since 1969 it has been evident that the FAST system becomes hydraulically loaded in wet weather events due to excessive inflow and infiltration, and overtops onto the tricking filter. A 2003 study into Schuyler County wastewater infrastructure 8 calculated that this occurs at combined flowrates above 0.49 mgd. Permitted effluent limits are as follows: Flow (30-day avge) 0.31 mgd TSS (7-day avge) 45 mg/l TSS (30-day avge) 30 mg/l TSS Removal 85% min BOD (7-day avge) 40 mg/l BOD (30-day avge) 25 mg/l BOD Removal 85% min UOD 135 mg/l The plant capacity is 0.31 mgd in line with permit and typical flows are in the range of 0.25 mgd. Although the system has consistently met TSS removal requirements, on three separate occasions between the monitoring period of 2002-2003 BOD has exceeded the permitted concentration. Several areas of Montour Falls are not serviced by the treatment plant, including the Havana Glen Trailer Park, L'Hommedieu St, Genesee St, Raymond St and the slaughterhouse at Seneca St. Instead, properties in these locations have onsite wastewater treatment and discharge arrangements. Concerns have previously been expressed regarding failing onsite septic systems at Havana Glen Treatment Park and Moose Lodge (Raymond St.) 9, and the proximity of slaughterhouse discharges to the

town wells10; including involvement by the New York State Department of Environmental Conservation and the Department of Health. 2.2.3 Village of Burdett Burdett is a small community with a population of about 300 people. The village is located to the east of Seneca Lake about 8 miles north of Watkins Glen. Residents and local officials take pride in the small community and while there is the desire for the town to flourish, there is also a desire to maintain small town appeal. The town is partnering with the Village of Odessa to engage in a planning process that will provide strategies to enhance the downtown area; including consideration of wastewater infrastructure. Currently, all of the lots in Burdett are serviced by public potable water supply in combination with individual on-site septic systems for wastewater service. There have been reported water quality issues due to poorly maintained systems in the Village and in the surrounding community. The 1996 Schuyler County Water Quality Committee Strategy Plan raised concerns regarding pollution to the Burdett aquifer due to the number of failed individual septic systems. This has been attributed to a seasonal high groundwater table which results in septic system failure in portions of the village. The immediate risk to the water supply of Burdett is low due to mains water supply from the Town of Hector, which detracts from the necessity to remedy the problem of failing septic systems. 2.2.4 Village of Odessa The Village of Odessa is located southeast of Watkins Glen and Seneca Lake and has a population of about 600 people. Wastewater treatment is by individual onsite septic systems. Like Burdett, Odessa has reported the failure of many individual septic systems. In the Village, average lot sizes are relatively small therefore there is little room to make improvements to systems where they may be failing. In 2003 the lack of adequate wastewater infrastructure was directly blamed for stifling local business

growth, and an improved Wastewater Treatment System made one of the top priorities for regional development 11. 2.2.5 Wineries, agriculture and related tourism According to the 2008 Agricultural Report 12: including economic multiplier factors, it is estimated the combined contribution of wineries and agriculture to the economy of Schuyler County is on the order of $100 million per year. As of 2008 there were approximately 400 farms and 22 wineries in Schuyler County. Small agriculture businesses have always been an important part of the fabric of Schuyler County, and a burgeoning tourism industry has created the opportunity to generate additional value and expand these traditional sectors; thus ensuring their protection. Both sectors have seen impressive growth over the past 10 years, and it is hoped that this growth will continue. However, concern has been expressed that lack of wastewater services to wineries could hamper this development. The level of wastewater treatment at different wineries is inconsistent, as can be expressed through a few case studies: 1. Fulkerson Winery produce about 80,000 gpy of wines and juices. During operations (6 month period encompassing pressing and retail) they use approximately 800 gpd of water for pressing and retail related uses. Wastewater is treated using a Septic tank

(about 1,500 gal tank) and leachfield on site. Additionally, 500 gal of wastewater is spread over about 1/8 acre of land to cut down on fertilizer use. The only costs incurred are for septic tank emptying.

2. Damiani Winery produce about 10,000 gpy of wine and produce about 20,000 gpy of wastewater which is collected and hauled to Auburn, NY for disposal (approximately 60 miles away). Total disposal costs are approximately $4,000 per year. The winery expresses that they would like to find an alternative way of treating and disposing of waste as current haulage expenses are limiting development.

2.2.6 Diffuse population in the larger Towns All Schuyler County properties outside of the four incorporated villages are served by individual wastewater treatment systems, which generally incorporate septic tank and disposal field. This represents approximately 75% of the County population or 7,475 properties. A report published by the Schuyler County Watershed Protection Agency (WPA) summarized results from investigations conducted into the reliability of individual wastewater treatment systems in the region. A total of 163 evaluations were conducted between 2008 and 2009, and of these a total of 13 systems required a complete replacement. Based on a failure rate of 8%, WPA estimated that 598 individual systems in Schuyler County may be failing 13. This large number of failing systems may have implications for environmental pollution and human health risks.

2.2.7 Wastewater solids, septage and leachate management

At one time, the Watkins Glen Treatment Plant had been accepting septage from commercial establishments in the town. Due to odor concerns from commercial neighbors at the lakefront, Watkins Glen WWTP no longer accepts septage from the households and businesses that rely on onsite septic systems, increasing the cost of septic management for those entities. There are currently three registered septage pumping and hauling companies in Schuyler County. Septage is driven to one of four land application sites: two in Tyrone (Hallock Road, Dean Lake); two in Hector (New Town Rd, County Rd. 4). The permitted application rate is 25,000 gallons of septage per acre per year, beyond which excess septage is hauled upstate. Agricultural and winery organic solids wastes such as grape residues and slurries are high strength and need careful land application. Where this is not permitted, alternative methods of disposal are required. A further consideration is the landill leachate collected from the Irelandville (Reading Center) landfill site. Currently leachate is disposed of in either Ithaca, NY or Geneva, NY (both approximately 32 miles away) and the current cost for haulage per year is $80,000.

Previous recommendations

Many of the problems discussed in Section 2.2 are not recent. Several previous reports on Schuyler County wastewater infrastructure have been performed and it is useful to review the recommendations made when considering possible solutions. Table 3 summarizes the findings of these reports. Generally speaking the following common recommendations have been made: 1. Solution: Move the Watkins Glen WWTP to a location south of the confluence between Catharine Creek and the Canal and expand for service to Montour Falls/Odessa/Burdett. Problems Solved: Frees up valuable lake front real estate, simultaneously solves hydraulic overloading issues at Montour Falls (due to storm flow) and Watkins Glen (due to raceway), and removes the dependence of Burdett and Odessa on failing septic systems. 2. Solution: Construct conventional wastewater treatment systems for Odessa and Burdett Problem Solved: Removes the dependence of Burdett and Odessa on failing septic system. The Burdett system would require tertiary UV disinfection for discharge to Tug Hollow Creek, and similar for the Odessa system if discharging to Catalin Creek. 3. Solution: Extend the Montour Falls sewer system to cover Havana Glen Trailer Park, L'Hommedieu St, Genesee St, Raymond St and the Montour Falls slaughterhouse Problem Solved: Remove dependence on onsite septic systems that have historically performed poorly and have a potential impact on regional water resources

One of the abiding themes of previous suggestions is an element of centralization. A baseline case is defined in Table 4 based on the best overall strategy propose by HUNT Engineers 14 for total improvements to Schuyler County Wastewater Infrastructure. This strategy uses conventional treatment technologies, involves centralization, and is accompanied by cost estimates, as defined below. This baseline case can be used to benchmark against alternative wastewater treatment solutions that use ecologically innovative technologies.

The discussed solution would have a capacity of 1.4 mgd including service to Watkins Glen International raceway. Estimations of carbon footprint are based on information from Kadlec and Wallace (2009) 15. In choosing the baseline case the following assumptions and specification choices were made: · The system would include trunk sewer connections between mains networks in Odessa and Burdett and the Watkins Glen Treatment Plant. Trunk connections to a completely centralized solution would be cheaper to operate and entail a smaller carbon footprint than conventional plants for Odessa and Burdett. The centralized system will also combine the flows from Montour Falls and the Irelandville Leachate Plant Capital cost information is obtained from the HUNT report Operational cost information is obtained from Salveson et al.

Community Wastewater Treatment Alternatives

Because water is a local issue with many variables, identifying and fulfilling community priorities is a key aspect of developing successful solutions. The site team visited Schuyler County at the beginning of June to inform the approach of developing concepts that are appropriate to each community. A tour of the local businesses and wastewater treatment facilities was held on Thursday, June 3rd in order to observe existing activities in the County and begin a conversation about the potential for ecologically-friendly future development opportunities.

A public workshop followed on Friday, June 4th to introduce the potential benefits of natural systems to community stakeholder, identify the major requirements, concerns and desires of the community, and to identify locations that the community agreed would be suitable for siting a wastewater treatment plant. Firstly, a SWOT (Strength, Weaknesses, Opportunities, Threats) Analysis was performed, followed by identification of priorities using the Water Environment Research Foundation (WERF) Decision Support Tool (Decentralized Wastewater Stakeholder Decision Model, WERF).

3.1

SWOT Analysis

STRENGTHS The natural beauty of the region, the lake, wineries, and various recreational activities on and near Seneca Lake support a growing tourism industry in the County. The Finger Lakes Distillery sees about 500-600 visitors on any given Saturday during the summer. The wineries receive marketing and PR support from the regional Finger Lakes Wine Trail Association and the Seneca Lake Winery Association, and technical support from the Cornell Cooperative Extension Service. Tourism has supported the economy of the area to the extent that some improvements within the larger communities have been made in recent years. Watkins Glen, for example, now has a high quality hotel that promotes sustainability practices such as water conservation, waste reduction, and the use of green products. The hotel is located directly on the Seneca Lake waterfront, which is undergoing a planning process to beautify the area and add functionality for recreation purposes. WEAKNESSES Infrastructure for sewer service is lacking in the smaller villages of Burdett and Odessa. In these areas, residential and commercial lots utilize septic systems and there is evidence that systems in the commercial district are failing or have failed. In some cases these systems have been repaired, however, repairs may be difficult because lots are small and there is not enough area to make appropriate upgrades. The lack of sewer infrastructure combined with small lot sizes further complicates the situation and makes it almost impossible for these communities to attract new businesses. Installing sewer services is essential in building capacity so that the villages can attract more visitors and more residents. The villages must utilize their planning capabilities to adopt plans that will dictate how growth should occur in order to maintain the rural character of each community.

19

As with any business, growth is a goal. The lack of sewer infrastructure is a downfall for the smaller communities as they have seen a decline in their local economies and in their populations partially due to their inability to accommodate that additional growth. The smaller communities could benefit from added sewer service as a catalyst for growth, but in the appropriate locations and to the extent they desire. The wineries, while successful on their own, are small and remain fragmented with little support from the larger tourism industry. In the larger communities of Watkins Glen and Montour Falls where sewer service exists, the infrastructure has potential to become more efficient. Watkins Glen WWTP no longer accepts septage from the households and businesses that rely on onsite septic systems, which increases the cost of septic management for those entities. The Watkins Glen WWTP also creates an aesthetic impact due to its traditional design and proximity to the waterfront recreation areas, the municipal beach and the new hotel. In addition, the plant discharges directly to the Lake, which is a risk that the community would like to see remedied. The Montour Falls WWTP has more significant performance issues including limited capacity for additional growth, and infiltration and inflow during major storm events. The issues may be resolved in the short-term with quick fixes; however a more long-term approach is needed to ensure the WWTP functions properly over time. OPPORTUNITIES Many of the opportunities for the Villages of Schuyler County and the tourism industry of the Seneca Lake Wineries, Distillery and Cheeseries rely on the availability of infrastructure to dispose of liquid and solid waste properly, efficiently, and without harm to the natural environment. Opportunities for the installation and use of natural treatment systems such as engineered wetlands were discussed as viable options for the smaller communities, in particular. Figure 1 illustrates where the proposed locations and existing wastewater treatment facilities are, on a map of Schuyler County.

When a parcel is selected, all pertinent info about the site is displayed to the right of the map.

In Montour Falls there are a number of areas that may be appropriate for relocating the WWTP. They include: · A natural wetland area located within the "square" of W. South St (NW), Owego St (NE), Mary Layton Dr. (SE), and Canal St. (SW). (#4a on the map) · A natural wetland area located within the "triangle" of Rte 14 (SW), Walker St. (NW), and College Ave. (E). This property is privately owned and is for sale. (#4b on the map)

A parcel just south of Rte. 224 classified as undeveloped "park". A parcel along the Canal and just east of the Marina. There is presently a FEMA flood mitigation floodplain project along a dike on easterly border of the Village, near this potential relocation site. Potential opportunity for shared services with Watkins Glen (Catherine Valley Sewer District, etc)

In Odessa, participants at the workshop identified the following locations for natural systems: · Two sites located just west of the forested area next to the school (south of Rte. 224) and just north of Rte 224 in the same area (near the corner of Cotton Hanlon Rd and Rte 224). (#5 on the map) · Scrub area along Catharine Creek southeast of downtown Odessa is identified as "wetland area" and could be a potential location for a decentralized system. Options for utilizing natural treatment systems within Watkins Glen or retrofitting the existing WWTP include: · Watkins Glen High School presently has a demonstration rain garden on site, which is near the Canal and may be a good location for a wetland treatment system. The school may be open to natural systems as an education component, as well. · An emergent wetland area located between the downtown area and the Canal, just south of Wal-mart. (#2 on the map) · Relocating the existing wastewater treatment system near emergent wetlands with an effluent pump station for transmission to the south into Queen Catharine Marsh. This option would eliminate direct discharge to Seneca Lake, and the assimilative capacity of the Marsh would further polish treated effluent. (#3 on the map) · Improving the existing wastewater treatment plant by minimizing the footprint of the plant, producing higher quality effluent (partial use / discharge) and utilizing the extra facility area as leasable space. (#1 on the map) · Potential opportunity for shared services with Montour Falls (Catherine Valley Sewer District, etc) For efficiency, shared services may be an opportunity for the communities to work with the wineries and other tourism businesses. Working with technical support groups and the member associations, the best approaches to shared water resource services can be determined; this may include shared management, operation and maintenance of physically discrete infrastructure systems. The school properties in Odessa and Watkins Glen may also

22

provide opportunities in two ways: 1) as a shared service opportunity and 2) as a water resource educational component to the school's curriculum. All of Schuyler County's municipalities have opportunities for future growth with appropriate and sufficient sewer service. Montour Falls and Watkins Glen, as the more largely populated areas, are targeted economic growth areas, with the potential to accommodate more growth than the smaller communities as long as infrastructure is provided or upgraded. Burdett may see additional growth with the proposed equestrian center. This development, if constructed, would provide an opportunity for economic development in nearby areas, including the Village of Burdett. Working with the developer, the Village has the ability to articulate their vision and ensure the proposed development does not threaten the small town character of the community. Through a potential public/private partnership the proposed project may offer shared services with Burdett, offsetting costs and assisting with economic growth in the Village. (#6 on the map) THREATS The communities of Schuyler County have witnessed firsthand the consequences associated with the recent economic downturn. The small villages of Odessa and Burdett are seeing decreasing populations, declining customer and business bases, rising costs, and an increase in failing septic systems, limiting the potential for economic development. In addition, a slowly growing business base in the larger communities of Watkins Glen and Montour Falls is detracting from the smaller communities' commercial base. Local officials and residents of the communities felt that while attracting new businesses to the communities would increase local economies, there is also the potential for the loss of community character and increased environmental impacts. In particular, the village of Burdett has an opportunity with the proposed equestrian center to improve the local economy, yet there is concern for impacts the project may impose on the surrounding community and environment. A "do-nothing" approach to current conditions could potentially create greater threats to the livelihood of county residents, the tourism industry that would otherwise flourish, and the local economic base that would otherwise have the opportunity to grow and prosper. The threats of population decrease, customer and business-related decreases, and rising environmental costs could be countered with the opportunities described above. Innovative approaches to addressing infrastructure issues would enhance existing conditions and provide

23

long-term efficiency throughout the communities and the tourism industry, avoiding potential threats that impact these entities.

Decision Tool Exercise Summary

Using the WERF decision support tool, participants were asked to assign importance to the following Values: Maximize Economic Value; Optimize Environmental Benefit; and Fulfill Community Objectives. These values portray the categorization of considerations under the modern acumen of "triple-bottom-line" metrics wherein decisions take into consideration the environmental and social aspects of the desired outcome in addition to the traditional economic benefits. Participants expressed widely diverse views, although, the final votes portrayed an evenly balanced ranking of importance among the values. Out of a possible 156 votes from 13 participants, the following tally was recorded: · Maximize Economic Value received 43 votes ­ Discussions covered the distinction between providing services to allow needed economic growth vs. finding solutions that were affordable and fairly balanced amongst residents; Optimize Environmental Benefit received 51 votes ­ There was relatively uniform agreement that water quality objectives were of great value; Fulfill Community Objectives received 53 votes - Providing essential community facilities and allowing the communities to exist and grow was also uniformly important.

· ·

Following a discussion of the differences between conventional centralized approaches and alternative decentralized wastewater systems approaches, participants were asked to rank the likelihood for success under a variety of related attributes associated with each value. The results of the ranking are shown below:

3.3

Community Wastewater Treatment Alternatives

The public workshop highlighted several important considerations: 1. The SWOT Analysis revealed that Villages do not have the financial means to make changes individually, which could threaten their ability to grow. Solutions may therefore exist in a shared services approach which may mean shared operations, shared management or shared physical assets; to improve efficiency and affordability. 2. Stakeholders are still keen to relocate existing Watkins Glen wastewater treatment facilities from the shore of Seneca Lake, and have proposed numerous suitable locations for a wastewater treatment plant. Village officials have expressed particular willingness to investigate public land opportunities for integrated natural systems to be located near the Catharine Creek.

25

The WERF Decision Support Tool Exercise illustrated that the community has very balanced priorities regarding the social, economic and environmental sustainability of green infrastructure solutions. The over-arching principles of the Green Infrastructure Strategy are: · · · Protect natural resources; Support the existing (and growing) eco-tourism potential in the County; and Identify and support short- and long-term goals for ecologically innovative and sustainable opportunities that will guide future physical and economic development.

Furthermore, the following development considerations have been identified as particularly important to the community via studies conducted by SCOPED: · · · · Existing business and job retention Future business and job creation Fundability and cost reasonableness Protection of agricultural lands

Applying the above general criteria to a specification for wastewater treatment systems, we proposed the following design philosophy: a. b. c. d. e. f. g. h. i. j. k. Identify opportunities for shared services between Villages Keep water balance local by returning water to site if possible Make affordable Minimize carbon footprint Identify opportunities for nutrient/water/energy recycling Identify opportunities for incorporating wastes from key economic sectors Utilize existing infrastructure Provide capacity for economic growth goals Eliminate discharge of secondary treated wastewater surface waters Use community identified parcels of land where possible Design so that incremental expansions can be accommodated in response to growth, as opposed to investing in redundancy in the hope of growth

26

Section 4.0

Feasibility of Alternatives

This section explores the suitability of different treatment technologies with regard to the specification given at the end of the last section. Firstly, the feasibility of over-arching possibilities such as decentralized treatment and nutrient capture are discussed. Secondly, the design constraints of the proposed geographical locations are explored. Thirdly, particular wastewater treatment technologies are considered on the basis of capital and operating costs, energy consumption, the ability to be accommodated in the suggested geographic parcels, typical effluent discharge quality and hence the need for tertiary treatment technologies, proximity to sensitive water bodies such as biodiversity wetlands or potable aquifers.

4.1

Possibility of different innovative ecological solutions in Schuyler County

DECENTRALIZED VERSUS CENTRALIZED Centralization has the potential to realize economies of scale by combining wastewater streams and allowing villages to pool physical assets. However, centralization requires a plumbing network to be constructed for wastewater conveyance which can be very costly depending on conveyance distances and soil geology. More importantly, concentration of wastewater generally requires energy intensive solutions with higher carbon footprints and operating costs, and shifts the water balance away from the point of abstraction. By decentralizing, opportunities to use natural wastewater treatment systems often become possible. System sizes can be smaller and built modularly to respond to community growth. Decentralized networks require a mobile operator, but communities can share management and operations of the different assets. The size of the communities, available land, and the distance between communities makes it very desirable to try and use decentralized technologies where possible. NATURAL VERSUS CONVENTIONAL Natural treatment technologies minimize operational carbon footprint, and often have very low operation and maintenance costs. However, their operation requires specialist knowledge if they are to perform consistently. Conventional wastewater treatment solutions are more robust, but have higher operating costs and carbon footprints. Natural systems have additional benefits such as ability for landscape integration, biodiversity and habitat creation. Based on the need for long term affordability and incremental capacity building, we will try and use natural treatment systems wherever possible.

27

RESOURCE CAPTURE AND REUSE As part of Alliance Environmental's design philosophy, we try to minimize the impact of waste by identifying opportunities to reuse waste as a resource. Decentralized networks allow treated effluent to be discharged closer to the point of abstraction, than would be possible if wastewater was conveyed to a centralized system. Discharging near the source helps to protect equilibrium conditions in groundwater tables. Other opportunities for water reuse could exist at a residential or industrial scale (e.g. plant process operations at the salt factories), depending on the needs of the community and the technology used. There is also the potential to capture nutrient rich wastewater solids (such as biosolids, sludges and septage) so that they can be stabilized, processed and reused locally for fertilizers. This has the dual benefit of offsetting the use of chemical fertilizer. As such, opportunities for reuse could simultaneously support local agriculture and reduce hauling costs of municipal septage and winery wastewater, by offering a local solution. We will explore the possibility of providing these facilities as part of our green infrastructure concept. Possible solutions could include sludge dewatering wetlands to produced fertilizer cake, or compact anaerobic digesters to produce biogas from winey wastewater.

4.2

Suitability of proposed geographical locations

Based on the outcomes of the public workshop, several locations were identified throughout the County which could provide capacity for a decentralized wastewater treatment network (Table 6). Parcels are scrutinized on the basis of available space, proximity to aquifers and protected wetland areas, soil quality and infiltration capacity, and site access. 1. Point #1 is the site of the existing Watkins Glen wastewater treatment plant. One option is to move the existing plant to free up the lakefront property for higher value uses, so these parcels will not be developed. Depending on the structure of the Watkins Glen sewer network, decisions could be made about whether the head-works and a pumping station need to remain at this site. 2. Point #2 is a 36-acre site in Watkins Glen at Parcel 65.18-1-46 owned by Cargill Salt. The soil type is silt loam with negligible gradient. Based on soil textural class, estimates of soil infiltration rate are 0.6 inches per hour, which is suitable for soil disposal. However, it is recommended that an infiltration test and mounding test are performed to determine whether this soil would be useful as a drainage field.

28

3. Point #3, is locally known as the Catharine Creek Marsh area just south of the Village of Watkins Glen. These points encompass parcels 76.00-1-40, 76.14-1-3, 76.14-1-4, 76.19-11.2, 76.19-1-2, 76-14-1-2. This land has highly saturated soil codes (AQ ­ Aquepts and Saprists) and would only be suitable for discharge to wetland. Tertiary treatment and permit application would probably be required. The site is adjacent to the Catharine Creek Wildlife Management Area which creates possible ecological risks given that there will be no soil disposal at this site. 4. Points #4a and #4b are narrow parcels of land located within a residential block in the Village of Montour Falls. The available area is the undeveloped parts of parcels 86.08-136, 86.08-1-37.1, 86.07-3-41.2, 86.12-1-4 (zoning R2) and comprises just over 10 acres of land. Soil types are silt loams which are generally suitable for drainage. Exploratory tests must be performed to establish the available head between Montour Falls and the groundwater table, and the infiltration rate of the soil. 5. Point #5 comprises two narrow parcels of land in Odessa. Altogether about 16 acres of mixed soils are available, which include steep Valois and Howard Soils (unsuitable for drainage), gravel and silt loams (potentially suitable) and frequently flooded fluvaquent and udifluvent soil types which border the creek (not suitable). More site investigation is required to determine whether there is sufficient suitable soil available to create required conditions for a drain field. The proximity to the creek surface waters may be an issue. 6. At Point #6, approximately 4 acres of Howard gravelly loam with a 3-8% slope will be available for a treatment system. This soil is probably suitable for drainage although infiltration tests are required to make sure that infiltration rates are not above 2.4 inches per hour. One additional parcel (Point #7) has been identified through discussion with the community, which is not indicated on the map. 7. Point #7 is located at Parcel 65.18-1-45.2, which is located easterly of the high school sports field, adjacent to the Canal. Approximately four (4) acres of land are available behind the baseball diamond.

Proposed Alternative Wastewater Solutions

Some wastewater treatment technologies are better suited to our remit than others. This will be illustrated by considering available technologies in several groups according to Salveson at al. (2009)17, and comparing typical design and operational parameters with the ability to meet specification. CONVENTIONAL CUSTOMIZED Conventional customized systems include Activated Sludge Processes, Extended Aeration, Anaerobic/anoxic/aerobic, biological nutrient removal, trickling filters and rotating biological contactors. These are well established and understood technologies which allow a high degree of process control and hence achieve robust treatment performance. Generally speaking, customized conventional processes involve large capital investments and require widespread centralized network coverage to achieve economies of scale. Maintenance requirements and energy consumption is relatively high. CONVENTIONAL PACKAGE Package plants emulate conventional wastewater treatment processes at a small, modular scale. Systems include Activated Sludge Package Plants (FAST etc.), Sequencing Batch Reactors, Oxidation ditches, biological filtration (e.g. AdvanTex). Package plants generally require a greater capital expenditure than equivalent conventional systems, but module sizes are usually small so that investment can closely match demand. MEMBRANE CUSTOMIZED SOLUTIONS These systems combine aerobic biological treatment with fine mesh membrane to achieve very high treatment performance. Membrane Biological Reactors and Reverse Osmosis filters are two such examples of this technology. Systems rely heavily on pumping and aeration and therefore have relatively large energy consumption. Systems are compact in comparison to equivalent activated sludge processes (one-third to one-half the footprint) and produce effluent quality which is suitable for indoor and outdoor, non-potable reuse applications.

17

Low-cost Treatment Technoliges for Small-Scale Water Reclamation Plant, Salveson et al. (2009), Water Reuse Foundation, Alexandria VA

NATURAL SYSTEMS Natural systems tend to operate without the electro-mechanical intensification which is synonymous with conventional treatment processes; however, they usually require larger land areas. Some engineering solutions have been developed which combine a small degree of intensification with natural purification processes to achieve systems with a practical footprint. Constructed wetlands, lagoons and ponds are all examples of natural systems. These systems generally have low operations and maintenance costs in comparison to other technologies, but specialist understanding is required to operate the system for good yearround treatment performance and robust operation. A tertiary treatment stage or drainage field is generally required to ensure consistent compliance. Ancillary benefits include integration with the landscape, biodiversity, habitat restoration, recreation, education and horticulture. ALTERNATIVE TREATMENT SYSTEMS Salveson et al. (2009) define the Living Machine as an alternative treatment system. This technology is a more intensified version of a natural system, and generally uses two wetland cells that reciprocate flow between then, thus often being referred to as `fill-and-drain' wetlands. The pumping volumes involved lead to high energy consumption. The systems are also quite capital-intensive due to the patented processes. The systems can, however, be integrated into nature to inherit the ecological benefits of natural systems but with the treatment performance of conventional systems. COMPARISON OF APPROACHES More information about the capital and operational costs, carbon footprint and achievable treatment performance of each group of technologies is given in Table 7. Table 7 compares each technological approach using the carbon footprint and life-cycle cost after 50 years, for 1 mgd per plant. It should be emphasized that typical cost information for these groups of systems is derived from Salveson at al. (2009) and should be taken as a guide in lieu of further research. The life cycle costs do not reflect inflation over the 50 year period cannot account for advances on technology or operation, and should be used for comparative purposes only. Carbon Footprint information is taken from Kadlec and Wallace (2009) and only considers the carbon equivalence of electricity consumption. The carbon footprint of chemical consumption, operator travel and additional impacts are not considered. Electricity consumption is converted to Carbon Footprint using an equivalent factor of 0.544 kg CO2 per kWh, as based on standard electricity production for US utilities.

Cons

Tertiary treatment required, and big footprint

It can be seen that natural systems have the lowest life cycle cost ($23 million net present value amortized over 50 years) and the lowest carbon footprint (6000 T CO2 emitted over 50 years). The second least expensive systems over a 50-year life-cycle are membrane bioreactors (MBRs). However, these systems require a large initial investment and have a large carbon footprint associated with operation. These systems could be useful where large-scale opportunities for reuse exist, such as in the salt industry, whereby the ecological benefits of reuse outweigh the carbon footprint associated with membrane bioreactor treatment. This discussion has emphasized that natural systems should be used wherever possible. The scenario(s) developed will be based on this notion.

Section 5.0

Natural Wastewater Infrastructure Concepts

Firstly we will propose natural treatment system solutions to the following wastewater infrastructure problems. · · · · · · · · · Watkins Glen Village Montour Falls Village Odessa Burdett The Havana Glen Trailer Park area Regional wastewater solids management (septage, sludges and biosolids) For treatment of landfill leachate at Irelandville landfill site Stormwater retention Winery wastewater management

The amalgamated systems would form a decentralized network of wastewater treatment systems which could benefit from shared management and operation services. Secondly, the scenario(s) developed are compared to the baseline centralized case from Section 2.0 in terms of life cycle cost, initial affordability and carbon footprint. There is a large degree of flexibility over the final solution and the proposed concepts should be used as an illustration of what is possible as opposed to final recommendations. Each approach would offer a different package of benefits to the community and flexibility will allow the community to identify which components would be most preferable based on their needs.

5.1

Large Treatment Wetland Plant at Watkins Glen

Under this scenario, a large treatment wetland system would be developed at Parcel 65.18-146 (Point #2) that would provide the combined wastewater treatment for Watkins Glen and Montour Falls. This strategy would enable the site of the current wastewater treatment plant to be redeveloped. Further analysis would be required to decide whether the current site would still house the head-works and a new pumping station. It is suggested that Watkins Glen International does not convey its wastewater to this location, as a more local solution would be more appropriate.

35

The 6-acre treatment wetland plant could consist of several Cold-climate ready, compact vertical down-flow treatment wetlands with Forced Bed AerationTM cells. These systems are top-insulated to provide year-round wastewater treatment in cold climates; an important consideration for New York State. The wetlands could be cultured to foster indigenous plant species. Additional landscape architecture services could be provided to integrate the systems into the landscape, and provide recreational and educational opportunities. The 6-acre site would have to be cleared to allow construction of the wetland cells as it is heavily vegetated. Sewage collection from Montour Falls and Watkins Glen will be by the existing sewer infrastructure, with the existing wastewater treatment plants converted into pumping stations. Primary treatment would be via primary clarification tanks. If a wetland module size of 50,000 sq. ft. is used then 17 cells would be required. The total treatment capacity would be 0.75 mgd which would replace the combined capacity of the existing Watkins Glen and Montour Falls treatment plants. The module size would help to maintain good hydraulic performance. Additional cells can be added at a later date in response to capacity growth. Based on a 0.6 inch per hour disposal rate through the Walkill Silt Loam it is anticipated that an additional 3.5 acres would be required for drainage. This leaves adequate room for plant expansion on the site at a later date.

5.2

Separate Treatment Wetland Plants at Watkins Glen and Montour Falls

Maintaining separate services at Watkins Glen and Montour Falls would enable treated effluent to be returned to the same region from where it was abstracted, thus closing the water balance for these towns. Under this strategy, the wetland plant discussed in Section 5.1 would be 3.5 acres and solely serve the capacity of Watkins Glen. The required area for drainage would be 1.84 acres. The individual capacity of this plant would be 400,000 gpd, and again it is suggested that the Watkins Glen International wastewater would not be treated at this plant. The system at Montour Falls would require 2.5 acres of treatment wetlands with an additional 1.5 acres required for drainage. This could be accommodated by the site at Point #4b (Canal St.) which has 4.4 acres of land available. The existing Montour Falls treatment plant would be converted into a pumping station to utilize the existing infrastructure. Primary treatment would be via a primary clarifier. If it is found that not enough clearance exists between the drainage field and the underlying aquifer, it is recommended that re-circulating sand filters are used as a tertiary treatment stage and a permit is sought for discharge to the canal. The

36

site would provide 350,000 gpd of capacity. One limitation of this site is that little room exists for further expansion in response to growth.

5.3

The Village of Burdett

Burdett would be serviced by individual cold climate ready, vertical down-flow treatment wetland cells. The site at Burdett would be 15,000 sq. ft., with a capacity of 45,000 gpd, and located at Parcel 54.00-1-3.1 (Point #6) where 4 acres are available for development. A 0.2acre drainage field would be installed into the Howard Gravelly loam on-site and wastewater collection would be via a Septic Tank Effluent Pump (STEP) system which would convey septic tank effluent to the wetland. The STEP approach is commonly used in more rural communities as a means of reducing wastewater collection costs and improving the overall performance of the wastewater system by using septic tanks at the individual homes to provide primary treatment. These septic tanks would be maintained under the direction of the sewer service entity, not the homeowner. This would help to counteract issues with failing septic tanks in this community. Approximately 4.5 miles of pressure sewer line would need to be installed around the village to enable connection between STEP systems and the wetland.

5.4

The Village of Odessa

The Odessa system would be similar to that of Burdett in that it would utilize the existing septic tank infrastructure for primary treatment, and make connections via STEPs. The system would be 30,000 sq. ft. and with a 0.4-acre drainage field into the predominantly FluvaquentUdifluvent soil. The total capacity would be 87,000 gpd. Based on available parcel geometry it is recommended that the system be installed at Parcel 87.16-2-1 (Point #5). With the Odessa system there are some features worth noting: the proximity of an adjacent stream, which may interact with the frequently flooded Fluvaquent-Udifluvent soils to create potential for disposal field failure. This possibility requires further investigation.

5.5

Havana Glen Trailer Park and surrounding area

It is estimated that the region that comprises Havana Glen Trailer Park, L'Hommedieu St, Genesee St, and Raymond St. would account for approximately 19,000 gpd of flow. A similar

37

STEP and vertical flow treatment wetland could provide service to this region. A system size of approximately 6,500 sq.ft with a supporting 3,800 sq.ft drain field would be adequate.

5.6

Wastewater Solids Management

To handle the wastewater solids management for the community, we believe it would be possible to use a 4-cell, 2-acre biosolids wetland located at Parcel 65.18-1-46 (Point #2) on the same site as the proposed Watkins Glen wetland treatment plant (regen system). This system would process up to 440 tons of dry solid waste per year, which is equivalent to the estimated solids produced by the residential population of all four villages in the County and with the same capacity again for agro-industrial biosolids produced by the wineries. This would provide a local solution for septage disposal and winery biosolid disposal, and alleviate some of the economic constraints which have been hindering growth. The stabilized solids cake can be processed and used locally as a fertilizer, thus reducing dependence on chemical fertilizers.

5.7

Irelandville Landfill Leachate

At the moment leachate is collected in storage vaults and then hauled to sites elsewhere in the region. In conjunction with the Schuyler Joint Landfill Commission it may be possible to explore the use of treatment wetlands at the landfill site, to provide leachate treatment. Much work has been completed on the use of treatment wetlands for this purpose 18, although further investigation would be required before confirming that this would be a possibility at Irelandville. Any developed system could be operated in the same regional network of decentralized systems which serve municipalities.

5.8

Stormwater management

Solutions for stormwater management could also be investigated as part of the concept for sustainable wastewater strategy. Alleviating run-off to combined sewers will reduce strain on wastewater infrastructure and reduce the chance of plant failure due to inflow and infiltration. Sustainable Urban Drainage Systems such as bio-swales, rain-gardens and

Mulamootil, G., McBean, E.A., Rovers, F.A. (Eds.), Constructed wetlands for the treatment of landfill leachates, 1999, Lewis Publishers, Boca Raton; London

18

38

stormwater retention basins could be incorporated into green spaces in the municipal areas of Watkins Glen and Montour Falls. The costs and potential of this solution require further investigation.

5.9

Winery wastewater management

Create a network of decentralized natural wastewater treatment systems to allow on-site treatment and disposal of the winery wastewater. These systems would most probably be horizontal subsurface flow treatment wetlands preceded by a septic tank, or roughing filter for particularly high strength wastes. Compact vertical flow systems could be incorporated where space is an issue. For example, an initial calculation indicates that a horizontal wetlands treatment system which provides wastewater treatment capacity for a winery which produces 100,000 gpy of wine would require 1,200 sq. ft. at a cost of approximately $65,000. Based on a current haulage cost of $0.2/gallon the payback time for a system like this to winery owners would be approximately 3.3 years. The cost and size of the system will depend on the size of the winery. This strategy would allow the wineries to take advantage of land they have and reduce dependence on wastewater haulage.

5.10 Cost of decentralized natural systems network

A conceptual decentralized network is costed in Table 9 so that it can be directly compared against the conventional alterative. To aid this, the projected cost or the wastewater treatment system as Irelandville Landfill Leachate Plant was excluded, as further research would be required before a suitable wetland design could be costed. This cost comparison also does not consider stormwater and solids management, as these factors were not considered in the 2003 HUNT report. It should be emphasized that the figures quoted are subject to the following conditions: · · · · · Budgetary cost estimates have an expected accuracy of +/- 30% No land acquisition included in costs Land requirements include 50% addition to meet regulatory requirements for disposal Costs are developed without site specific information (topgraphy, soils, ground water, etc.) Septic Tank Effluent Pump (STEP) unit is purchased by homeowner

As evident from Table 9, it is estimated that to provide wetland treatment to Watkins Glen, Montour Falls, Odessa and Burdett would cost in the region of $24.2 million. Annual operating expense is expected to be $401,500 per year with an associated carbon footprint of 107 T CO2/yr. This compares very favorably to the conventional baseline case which required a capital expenditure of $34.1 million, and had annual operational impacts of $562,100 per year and 700 T CO2/yr. When the life cycle cost and carbon footprint of each option are

40

considered across a 50-year period it can be seen from Table 9 that the decentralized natural treatment network would save $13 million (22%) and 29,400 T CO2 emissions (85%) when compared to a regional centralized conventional wastewater treatment plant. Most importantly, a decentralized network can be built out incrementally to aid gradual affordability; unlike a centralized system which would require to be built to capacity in the first instance. The proposed scenario is conceptualized in Figure 2.

The Proposed Concept

Section 6.0

Funding, Implementation and Operations

In addition to which technology is selected and where the treatment systems are located, how the systems are funded, built and operated are equally important considerations that will be discussed, but not thoroughly developed at this stage. To some degree, these business decisions interrelate with the technical choices and our primary intention here is to illustrate some of the innovative approaches that are available. Detailed investigation of the specific laws which control each option along with understanding the nature of all existing entities is required to make an informed choice with regards to these options, some of which can help overcome current financial and political hurdles. The table below illustrates the options available for ownership and management beginning at the municipal/county level. The characteristics listed are typical and can sometimes be modified by contracting methodology which allows blending of characteristics to match goals and objectives. Ownership of wastewater systems in New York can take several forms that offer differing capabilities and complexities. The form of ownership of the future wastewater facility should be considered as soon as possible in the planning process so that the actions taken to control and implement new facilities and upgrade the existing facilities fulfill the operating protocol and financial goals of the future owner. Whereas, these objectives will be similar with regards to the environmental attributes, they could differ with regards to the details of the facility functions and methods of financing. It is important to match the characteristics of the owning and service entities with the required skills and operating capabilities of the solutions selected. It is not necessary to have water supply and wastewater infrastructure owned by the same entity, but there are operating and financial efficiencies that can be gained by combining these assets together. Combining the wastewater and water systems under one operating entity provides for more efficient labor and customer service and avoids potential duplication from overlapping aspects of these related asset functions. The same holds true for stormwater facilities, although these needs are less pressing at this time but likely to evolve in a similar manner in the future. The typical wastewater and water ownership options are illustrated in Table 8 and discussed subsequently.

6.1

Governmental - Municipal/County

A governmental entity or entities could own the wastewater and water assets as a part of the municipal infrastructure and operate the system as a separate utility under the municipal governing body or as a part of the public works department. This is the current form of ownership of the existing wastewater and water systems. Municipal ownership offers some advantage with regards to access to public financing, but is somewhat more complicated with regards to civil service employment regulations, procurement regulations and the influence of local politics on the system management. Having the backing of the municipality's taxing power is advantageous for financial security and ability to qualify for low interest funding, but having the infrastructure be financially self sufficient and fully supported by customer rate charges is normally desired. The taxing power of the municipality should only support the financing and not supplement the system operation. Under the municipal option, services can be provided to surrounding municipalities via interlocal service agreements, but such arrangements can raise concerns over time with regards to appropriate cost allocation and fairness to the outside communities.

6.2

Quasi-Governmental ­ Authority, Special District, Public Nonprofit

The formation of a wastewater or combined water and wastewater authority provides a quasi-governmental management alternative that generally qualifies for all of the financial benefits offered by municipal ownership and carries many of the same procurement and management characteristics. The governing body of an authority is generally appointed by the participating municipal governments or county government, as appropriate, and secures independent financing by loans and bonds that are backed by the general obligation of the municipality's or county's taxing power. Under this alternative, the assets must be fully financed by the revenue from rate payers and the debt is generally outside of the municipal spending caps. This approach has the advantage of being somewhat independent of the political climate of the municipality but this sometimes presents difficulties if the authority develops ambitions that differ from those of the governing bodies. The operating charter of the authority is defined in the initial formation but then is difficult to change once bonds and loans are secured. It is therefore not a flexible asset management mechanism unless defined as such initially. Quasi-governmental entities generally follow the same civil service labor and operating characteristics of governmental entities and thus bear similar cost characteristics. The ability to create service territories that cross municipal boundaries is an advantage, but

45

requires good cooperation of the participating entities to define and meet all competing goals and objectives.

6.3

Private Nonprofit Cooperative or Association

A private nonprofit entity such as a cooperative or association can be formed by the system users as one alternative. Homeowner's or landowner's associations are one example of such an operating nonprofit entity supported by association fees paid by property owners for operation and maintenance of the facilities. Cooperatives are common and very successful in the area of power supply utilities, but are not commonly used for water and wastewater although the legal provisions generally exist. The Homeowner Association is a more common form of asset management which sometimes encompasses water and wastewater systems in addition to other commonly shared assets such as parks, roads, community centers, etc. The association can also be a special purpose entity focused only on the management of the wastewater/water assets. A cooperative or association form of ownership separates the municipality for the financial responsibility of the facility's operation and management but this form of ownership is less viable with smaller customer bases which may lack the ability to provide adequate management and financial discipline. Associations often have difficulty managing complex assets effectively and can experience financial problems if funding and maintenance are not adequate. Ultimately, if an association falls into financial difficulty the municipality is the next logical entity in line to provide assistance, so even though there is no legal liability there is a practical responsibility that can implicate the municipality should problems arise.

6.4

Private For-Profit Utility ­ Transportation Corporation

A private utility can own and operate both wastewater and water assets in New York, but the control mechanism differ somewhat. The New York Public Service Commission regulates the financial and service aspects of water utilities but private wastewater entities require local control under the Transportation Corporation rules. A private utility is the most independent form of ownership wherein the municipality does not have any financial or physical obligations for the asset management. The municipality does have the ability to control the service area of the utility by defining the service area via approval of a franchise area that defines the geographical limit and type of the service provided. The municipality also has power to regulate user rates under the Transportation Corporation rules. The private utility is

46

financed by private equity and a combination of private and public debt financing. The systems for Watkins Glen and Montour Falls are large enough to readily become viable private utilities but stand-alone facilities to service Odessa and Burdett are very small for this model, although examples of this form of ownership exist in other states, some with passive type treatment systems being utilized. These smaller villages could be combined with the larger service areas of Odessa and Burdett and thereby form one larger and more viable utility. In some instances, municipalities monetize existing assets by selling them to private utilities in order to raise funds for other uses. 6.4.1 Public Private Partnerships The Public-Private Partnership (sometimes referred to as a P3) arrangement is a more recent means of monetizing asset value without transferring ownership. Under this alternative, the governmental entities retain ownership and transfer operation and financial obligations to a private entity under a long term contract, generally 20 years or longer. In this example the contract which creates the P3 must clearly detail the financial and management obligations and performance requirements. Such contracts are often renewable at the end of the initial term, or transfer responsibility back to the municipality at that point in time. This approach is becoming more common where upgrade and new facility requirements are more efficiently built and operated via a private entity but financing is more efficient with a combination of public and private debt. Underwriting such arrangements with adequate financial performance guarantees is generally accepted as a means of assuring performance. This model is very common in the renewable energy sector where new facilities are required and is now more commonly considered for water and wastewater assets. Funding opportunities encompass many traditional options associated with municipal bonds, State Revolving Fund and private sources of funding.

6.5

Funding Opportunities

There are an array of funding opportunities that are all moving targets based on status of federal and state funding mechanisms at any given point in time and readiness of the facility plan to be funded. Most funding agencies require well established and detailed plans prior to approving any funds. Recent green infrastructure initiatives have established zero interest

47

loans and grants for sustainable approaches which fit the natural system concepts set forth herein. Reviewing the various mechanisms with J.C. Smith recently highlights the following: a. USDA Rural Development ­ currently has a 3 ­ 5 yr backlog due to popularity and beginning an early screening and scoring effort is worthwhile. Get on the list. b. State Revolving Fund ­ Continued federal support sends signals that this still remains the primary funding mechanism for municipal wastewater facilities. Hardship financing and Green Innovations Grant program still exist and provide grant opportunities. c. HUD Community Block Grants are still available throughout NY which offers approximately $15M/yr spread around approximately 15 grants. d. Appelecian Regional Commission e. Economic Development Grants ­ extremely limited and focused currently on job production

Section 7.0

Conclusions

Schuyler County is a vibrant community of small towns and villages supported by a burgeoning agricultural, winery and tourist industry. Opportunities for further economic development rely on the expansion of wastewater infrastructure. As part of wider sustainability objectives this report has explored the potential to meet wastewater treatment needs with innovative ecological solutions such as natural systems. It was found that current wastewater capacity is substandard for supporting future growth. The Villages of Odessa and Burdett, and parts of the Village of Montour Falls, suffer problems with failing septic systems. The Watkins Glen wastewater treatment plant is forced to capacity during race days at the Watkins Glen International Speedway. The wastewater treatment plant at Montour Falls is susceptible to inflow and infiltration during wet weather events which cause overflow. To properly understand the needs of the community research has included a review of previous studies into Schuyler County sewer services, an appraisal of the current situation via site visits, and the outcomes of an interactive public workshop where community members expressed their priorities regarding the service that wastewater infrastructure would provide to the community. Previous work by HUNT Engineers had suggested creating a regional centralized activated sludge process wastewater treatment plant. This was used as a baseline against which to compare decentralized natural system wastewater treatment networks. A specification for concept proposal was developed from research, and it was believed that this is well answered by using a network of constructed wetlands to provide wastewater treatment solutions.

a. Identify opportunities for shared services between Villages

The decentralized network can be managed, operated and potentially owned by the same entity. This will help to pool human resources and expertise while allowing physical assets to be local to each village. b. Keep water balance local by returning water to site if possible

49

Using a decentralized network allows wastewater treatment within the proximity of the source, such that the regional water balance can be closed. c. Make affordable The proposed decentralized natural system solution has a life cycle cost which is 22% lower than an equivalent centralized alternative. The decentralized network can be built out incrementally which allows flexible fund investment; as opposed to a centralized conventional solution which would require capacity build out upfront. Opportunities for external funding have been explored, including private utility, to make these opportunities more instantly realizable. d. Minimize carbon footprint The proposed decentralized natural system solution has a 50-year carbon footprint which is 85% lower than that of the conventional alternative. e. Identify opportunities for nutrient/water/energy recycling A biosolids dewatering wetland incorporated into the larger wetland network would allow septage, biosolids and sludge to be treated locally. Additional to reducing local costs for hauling waste there is the potential to recycle stabilized cake as fertilizer to support the agricultural sector. f. Identify opportunities for incorporating wastes from key economic sectors It is suggested that a network of small wetland be developed to provide onsite wastewater processing for wineries. The needs of the salt industry are unclear and further research is required to recognize opportunities for benefit. g. Utilize existing infrastructure The proposed solution would use the existing wastewater networks of Montour Falls and Watkins Glen for conveyance, but replace existing plants with smaller pumping stations. This will allow prime lakefront real estate to be redeveloped. Solutions for Odessa and Burdett would provide support to the existing septic tank stock, so that these assets can still be used but without the problems that have historically existed.

50

h. Provide capacity for economic growth goals The proposed solution enables wastewater infrastructure to be affordable. The modular approach will allow additional capacity to be easily installed in response to growth; thus removing the risk of over-investment.

i.

Eliminate discharge of secondary treated wastewater surface waters

The replacement of the existing Montour Falls and Watkins Glen treatment plants will remove instances of direct discharge to surface water. The costed solution entirely involves subsurface discharge, however, the ability of these soils to achieve this requires further onsite investigation. j. Use identified parcels of land where possible All of the locations for proposed wastewater treatment plants are based on the outcomes of the Public Workshop The proposed decentralized network of natural systems for Watkins Glen, Montour Falls, Odessa, Burdett and the un-serviced regions of Montour Falls has an estimated capital requirement of $24.1 million, which can be invested in phases, and will provide 901,000 gpd of wastewater treatment capacity to the region. Considering capital and operational expense, the 50-year cost of life-cycle and carbon footprint for the network have been estimated as $44 million and 5400 T CO2. This represents a savings on expenditure of 25% and a savings on CO2 emissions of 85% in comparison to the alternative centralized activated sludge system. We believe that further opportunities for sustainable wastewater infrastructure in the community include wastewater solids management, winery wastewater management, landfill leachate treatment, and stormwater management. These opportunities require further investigation in conjunction with SCOPED, but they could be developed in tandem with the proposed municipal wastewater network.
