Chapter 12 Facilities Maintenance


Within the Process Control Division, the Facilities Maintenance Section=s main responsibility lies in the proper care and maintenance of mechanical equipment, piped utilities, structures, buildings and grounds within the department=s eight wastewater treatment plants and chemical feed systems at several sewage pump stations. The section=s maintenance personnel perform many building trades such as machine repair, welding, machine shop services, plumbing, heating/ventilating/air conditioning service, locksmith service, roofing and masonry work. Regulatory requirements have resulted in having our air conditioning system technicians E.P.A. certified for refrigerant transition and recovery, and also for chemical water treatment of equipment cooling towers. The staff maintains over 5,000 pieces of mechanical equipment, 180 tanks, 20 miscellaneous structures, and 54 buildings, mows 20 acres of lawn and snowplows the parking lots and several miles of service roads at seven facilities.

In addition to the plant maintenance programs, this section is also responsible for the department=s Inventory Control and Stockroom Operation, Archive Records Control, Materials Management/Surplus Equipment Disposal, Office Waste Paper and Scrap Metal Recycling. For several plants, the section also handles Custodial Services and Pest Control. It is also heavily 113

involved in construction design review for any plant upgrades and capital improvement projects. Besides using the traditional techniques of standard preventive and corrective maintenance, the Plant Maintenance Management System takes a Aproactive [email protected] by utilizing specialized programs that include Predictive Maintenance (PdM) through machine monitoring and vibration analysis, laser shaft and sheave alignment and lubricant wear-metal analysis. System re-design and small new construction/equipment installations are also performed on a limited basis. Five of the eight plants are staffed full time with maintenance personnel, with the remainder being serviced weekdays on a part time basis. Plant Assistance Crews (P.A.C.) are utilized to relieve the smaller plant crews from the burden of doing time-consuming major repairs and/or in-house new construction projects, thereby reducing the disruption in daily maintenance programs. The program has smoothed out the maintenance management effort and the special team approach is a tremendous success. During 2002, Plant Maintenance Supervisors set up in-house training sessions on many of the different trades utilized within Plant Maintenance. This insures the quality of work performed is kept at the highest level and that employees are not apprehensive about tackling the more difficult jobs. The training also serves to improve their self-esteem and degree of professionalism. The in-house training program has taken a positive move in that the concept of on-the-job-training continued all year, and the utilization of the knowledge gained in the classroom has been passed on to several new and long term employees alike. This process has encouraged a sense of total cooperation within the Maintenance section. Formal informational sessions were held for several affected plants for proper handling and safety of Liquid Oxygen and Aluminum Sulfate chemicals.


For 2002, all of the Maintenance crews were involved with mandatory training programs also, such as fork truck operation and safety, the ARight To [email protected] Law and chemical emergency response training. The Predictive Maintenance Program, although understaffed and not able to monitor equipment as frequently as we would have liked to through the year, has continued to be a substantial cost saving asset. Through machine monitoring by vibration analysis, the program has proven it=s worth by detecting machinery mechanical faults in their infancy and preventing unscheduled downtime. By finding a problem earlier and preventing collateral damage to other equipment parts, the program has been a huge cost saving effort. The expanded use of laser alignment between motor and equipment drive-shafts and laser drive belt pulley alignment continues to provide savings in equipment parts and labor expenses, to reduce equipment downtime and electrical power costs. C.M.M.S. Project Working with the consulting firm of Stearns & Wheler, L.L.C., the department continued building a new information management system by way of implementing a Computerized Maintenance Management System (CMMS) to manage the operation and maintenance of six (6) major wastewater treatment plants, over 100 pump stations, eight (8) Combined Sewer Overflow (CSO) treatment facilities and approximately 3,000 miles of sewer piping. Every division of the department was involved in the project with the Plant Maintenance sections Superintendent being Project Manager. The new information management system includes the following features: * A Computerized Maintenance Management System (CMMS) to manage maintenance work orders, provide equipment history, supply and parts inventory management and maintenance cost tracking. * A geographical Information System (GIS) interface with the CMMS to allow on-line viewing of the entire collection system, rapid assignment of work orders to any sewer line or manhole in the system, easy retrieval of maintenance history on any element of the sewer system, rollup capabilities to analyze and summarize maintenance data by work type and geographical area, and ability to generate billing reports for maintenance services. * A department-wide [email protected] providing rapid access to reports, documents and O&M information on all treatment facilities and pump stations and other data and information required for operation, maintenance and administration. * A drawing database for on-line retrieval of sewer, plant and pump station design drawings. The project impacts most every division in the department. Several department core teams were formed to work specifically on Maintenance, Operations and Information Technology areas of the system. The project began in March of 2001, has progressed from site assessment and business process analysis, core team training, through strategic planning and design document development, equipment nameplate data collection; storeroom parts and material identification, pricing, data collection; and end user training, Facilities began to go on-line in a staggered sequence from February through December of 2002. This transformation from a manual record 115

keeping system to electronic automation includes materials ordering, receiving, issuance and conducting inventory physical counts. Benefits for the department include: * Wireless Bar Code Scanning for receiving, issuing and physical count updating * Improved accuracy of records * Speed up parts receiving, locating, issuing * Improved/faster customer service * More timely ordering/ less stock outages * Standardize stockroom operations, labeling of materials * More efficient issuing of stock * Allow instant, automatic, complete and accurate reporting * Improved cost center accounting and budget forecasting * Electronic Purchase Requisitioning * Electronic Work Requests with helpful attachments such as work plans, diagrams, precautions and status viewability * Equipment parts reserved to Work Orders * Improved allocation of maintenance resources to decrease overall cost of maintenance and improved maintenance efficiency * Enhanced ability for supervisors to review and upgrade Preventative Maintenance Schedules * Ability for anyone to look up equipment parts, parts availability in Storerooms, diagrams, maintenance procedures * Improved interaction between Operations and Maintenance staff for coordinating equipment or system outages for maintenance * A resource database providing rapid access to on-line Operations & Maintenance Manuals, Standard Operating Procedures, thousands of treatment plant, pump station and sewer drawings as well as selected manufacturers drawings and photographs * Hyper-Links to other internet sites * Ready availability of system maps for maintenance planning, scheduling and work order implementation * Sophisticated reporting capabilities for billing, maintenance cost analysis, inventory management *Work Requests tied to G.I.S. Interface allow faster service, recording maintenance, reporting, and billing. The Department is in the process of developing an AOwnership [email protected] to take over the administration responsibilities of the CMMS from the consultant. The team will provide oversight and monitor and guide the usage, maintenance and growth of the O&M Information Management System by utilizing representatives from the departments various divisions and user types.


Long Range Planning and Facilities Upgrade

The challenge of operating and maintaining aging wastewater treatment facilities, while being faced with shrinking budgets, grows larger each and every day. It has been estimated that today=s replacement cost for our seven treatment plants would be over A BILLION dollars. Many of our plants are approaching, or have exceeded, their design life. Some of the equipment dates back to 1959, with some parts having to be manufactured in-house due to their obsolescence. The Department must stay on course with the long-term improvement plan. Besides capital improvement funding, annual operating budget money must be made available for new equipment, upgrade projects conducted in-house and out-sourced upgrades in order to protect our investment and meet regulatory mandates. In addition, adequate training and staffing levels need to be maintained to provide the manpower necessary to conduct the required maintenance of Department facilities. The Maintenance section was involved in the following projects during 2002: * HVAC Improvements at Metro and Oak Orchard (initiate and review design, monitor construction) * Metro Digester #2 Roof Repair (bid specification, monitor project) * New Screen and Grit Bldg. Dry Well Cover (design review, monitor construction) * Metro Ammonia/ Phosphorous Removal Project (design review, monitor construction) * CMMS Project (initiate and manage project) * Metro Primary Effluent Bypass Structure Weir Replacement (initiate and review design, monitor construction) * Metro Secondary Clarifier Improvements (design review, monitor construction) * Oak Orchard Odor Control System Project (design review, monitor construction) * Brewerton Sludge Thickening and Miscellaneous Improvements (design review, monitor construction) * Variable Speed Drive Upgrades (design review, monitor construction) * Baldwinsville Odor Control System (design review, monitor construction) * Jamesville Penitentiary Plant Conversion to Pump Station (facilities study, design review) * Harbor Heights Conversion to Pump Station (initiate project) * Roadway Repair (initiate and maintain ongoing project) * Roof Replacements (initiate and maintain ongoing project) These facility upgrade projects require the maintenance staffs support in the design process and during construction, interfacing with the contractors to accomplish major building construction/modification, equipment repair and replacement to keep the multiple projects on schedule, ensure quality equipment is purchased, properly installed and that process remains uninterrupted. Many staff hours are dedicated to de-watering and cleaning tanks, opening and closing valves and coordinating plant maintenance activities with construction efforts.


Operations Review

The plant maintenance section staff numbers have been reduced over the past several years due to budgetary constraints. At the same time, three new Odor Control Systems and a new Chemical Feed Facility have been placed on-line in the department, with a fourth Odor Control facility on the drawing boards. Maintenance has also taken on the chemical feed portion of two remote pump stations. All of these came with no additional staff. The Section is working under conditions similar to other departments, whereby facilities are aging at the same time they are expanding, requiring the staffs to perform with an increased level of efficiency. In some cases, major repair work must be contracted to outside firms, where there is insufficient staff and it is cost effective to do so. With the addition of a Mechanical Engineer to the staff in 2000, this division continues to get caught up on a backlog of projects that has existed for many years, many of which involved investigating problems and finding solutions that take many hours of research. This position is also utilized to review preliminary construction design to ensure that we get the best possible equipment, building, structure and process systems design and assist other sections in the department.

Plant Maintenance

Preventive Maintenance tasks represent approximately 50 % of the total workload with Corrective Maintenance and new construction tasks compiling the remaining 50 %. The numbers are expected to shift to a higher percentage of preventive maintenance through the use of the new Computerized Maintenance Management System. In addition to the routine daily care of existing equipment, buildings and grounds, a large and growing number of major repairs, rebuilds, equipment replacements and building repairs have taken place. An abundance of pumps, doors, large valves, compressors, pipelines, lawn hydrants and roof fan/exhausters have being replaced. Extensive roadway and roof repairs/replacements and the number of construction projects mentioned previously are indicative of the amount of repair/maintenance work done to the existing facilities that were built between 1959 and 1980. The 2002 accomplishments listed below include several process and money-saving improvements. They also show an increasing amount of modification work being completed in-house to keep up with the needs of other sections within the department. The ever-increasing workload will require careful review of staffing and funding considerations to keep pace with it.

This includes the following related aspects of the project. * Assisted the Stearns & Wheler consulting staff with the data collection phase of the project. * Began the actual usage of the Maximo inventory control automation software, for the materials issuance, materials receiving, materials ordering, and the conducting of physical inventories phases of the inventory control functions. * Performing of the related AQA B [email protected] (Quality assurance and quality control) review and correction of the data collected, phase of this important project. * Attend the necessary training to ensure the proper usage of the Maximo software. * Began to recommend the development of Maximo generated inventory control custom reports. * Continued to adapt and modify certain inventory control storeroom operational procedures, to ensure a [email protected] and proper transition to the new Maximo inventory control automation software. * The continuous evaluation of the overall performance of the Maximo software, and any related inventory control or general business functions.


(B) Inventory Valuation Project The inventory control section took the lead in determining the value of all inventories throughout the department for the dual purpose of preparing to create the Asatellite [email protected] in the Maximo software where parts, supplies and materials are stored at facilities outside of the normal stockrooms and to comply with a requirement to report the overall year-end department inventory value for the County=s financial statement. Completing the work for the stockrooms already using Maximo software, the following work was performed: Metropolitan, Oak Orchard and Ley Creek Stockrooms* Running reports to list inventory line items in Maximo that need pricing information entered into the system. * Work in cooperation with field supervisory staffs to obtain pricing information for specialized materials, for entry into Maximo where needed. * Obtain and enter pricing information into Maximo for standard stock materials. Satellite Stockrooms: * Work in cooperation with field supervisory staffs to assist with the coordination and review of inventory and materials pricing information that was collected. * Forward inventory information collected and reviewed to designated clerical staff member for data entry into Microsoft Excel database. Provide informational or instructional assistance as needed. Fleet Maintenance (Metropolitan, Liverpool, and Burnet Ave) facilities. * Conducted physical inventories of parts and materials, resulting in 3,536 inventory line items being inventoried at the three facilities. * Work in cooperation with fleet maintenance field and supervisory staffs to identify the parts or materials, or to obtain pricing information as needed. * Entered the information collected into a Microsoft Excel database for inventory value calculation, and potential future use for the creation of an automated inventory control database. (C) Storeroom reorganization project This project has involved the entire inventory control group. The primary goal of this continuous reorganization project is to utilize the available storeroom and materials storage areas in the most efficient manner. Individual storeroom accomplishments are detailed later in this report. (D) Collection of Hazardous Materials for disposal During 2002 the inventory control staff continued to collect used lighting lamps containing mercury and dry cell batteries for proper disposal. These items were collected at the four primary storerooms, Metropolitan, Fleet, Oak Orchard & Ley Creek. (E) Space Utilization study & design Members of the inventory control team have been working in cooperation with other Departmental groups to participate in a space utilization study & design for specific areas within


the Department that will be vacated when the new Henry Clay Facility opens in 2003. This project also includes participating in the design of the new Henry Clay storeroom facility. The overall goal of this project is to utilize all available space in the most efficient manner. (F) Asset, property identification and bar code labeling project. The Inventory Control Supervisor worked in cooperation with the Onondaga County Materials Management Coordinator on this project to identify and bar-code label a total of 110 assets.

2. Individual Storeroom accomplishments

Although each of the four individual storerooms within the inventory control section is part of the inventory control team, each storeroom made the following individual accomplishments, that were in addition to the above listed group accomplishments. (A) Metropolitan (Main) Storeroom Storeroom reorganization project Progress continued with the reorganization of the Metro storeroom facility, and related materials storage areas, resulting in the following accomplishments:

Number of New Shelf Bins Created 460

Number of Line Items Reorganized 830

Number of Shelves Reorganized 170

Number of New Shelves Added Or Changed 20

Number of Bar Code Labels Created 85

This project also included the reorganization of two first floor primary materials storage areas B (bays) of the Metro pole barn. This allowed for the fabrication of a new pipe storage rack and a new steel storage rack that were placed in one of the bays of these reorganized areas. This resulted in 70 line items being reorganized within these areas. In addition a portion of the second floor storage area of the pole barn was cleaned and reorganized, allowing for obsolete materials to be identified, and were being prepared for auction. Shipment and materials staging and receiving area Progress continued with the creation of a shipment and materials staging and receiving area. This area is being created to accommodate the need for an area within the Metro storeroom facility that would be dedicated specifically to receiving shipments and materials. This area will allow for an efficient flow of shipments or materials throughout the Metro storeroom facility. This area will include; * A materials receiving and sorting counter for conducting Quality Assurance and Quality Control (QA-QC). * QA-QC inspections of materials that have been received.


* * *

A materials staging area for materials to be staged the will either be placed into stock, have vendor discrepancies, or are awaiting other status. A shipment staging area, for the shipments that are either for the storeroom or other departmental sections and are awaiting pick up by the designated ordering party. A clerical work station or desk area that has a computer that is designated for materials receiving information data entry into Maximo.

Installation of new HVAC B (Heating, Ventilation, and Air conditioning system) During 2002 a new HVAC system was installed in the Metro storeroom. This will accomplish the following: * Provide an climate controlled environment that will allow for materials to achieve their maximum shelf life potential. * Provide a climate controlled work environment that is conducive to employee productivity, and is relatively free of harsh environmental employee stress factors such as heat, humidity or cold. * Frequent moving of materials to accommodate ductwork installation and the cleanup of incidental dust and debris from shelving units and materials was completed by the inventory control staff. Employee apparel B (coveralls & shop coats) A group [email protected] pilot [email protected] During 2002 the Metro storeroom staff was involved with a test B pilot program that would issue employee apparel to a specific work group in quantity, instead of issuing individual apparel to employees at the service counter. This pilot program has resulted in the following initial findings: * Decreasing service counter traffic, shortening the waiting line for parts pick-ups. * Allowed the employees within the monitored work group to focus more on their specific work activities, by having the apparel more readily available in their designated work area. * Allowed for the Metro storeroom staff to concentrate more on their specific inventory control activities, initially resulting in an improvement of operational efficiency. Obsolete materials identification program The Metro storeroom staff continued with the process of identifying obsolete materials. This has resulted in 165 inventory line items being identified as obsolete. This material will be prepared for auction, and the auctioning process will be coordinated through the Onondaga County Materials Management Coordinator. (B) Metropolitan (Fleet) Storeroom & Satellite Storeroom Areas During 2002 the inventory control staff continued to evaluate and improve the various services and functions provided by the Fleet storeroom facilities. The Fleet Storeroom consists of three primary storeroom areas located at the Metro, Liverpool Garage, and Burnet Ave facilities and is staffed by a Storekeeper. These storeroom facilities supply the fleet section with the necessary automotive related parts for vehicles and ground


equipment at several Onondaga County Departments including: * Department Of Water Environment Protection. * Sheriff=s Department. * Parks Department, including facilities located at: (Beaver Lake Nature Center, Carpenter=s Brook Fish Hatchery, Veteran=s Cemetery, Highland Forest, Hopkins Road Park, Jamesville Beach, Onondaga lake Park, Oneida Shores, P&C Stadium, and the Rosamond Gifford Zoo.

M.O.S. - (Mutual Ordering System)

During 2002 the Inventory Control Section continued utilizing the Mutual Ordering System (M.O.S.), that was originally implemented in the year 2000. The M.O.S. is a mutually cooperative system of combining orders for general commodities between the facility Storekeepers of the individual storerooms at Metro, Oak Orchard, and Ley Creek. Prior to the implementation of the M.O.S. the three facility Storekeepers at different time of the year would each write an individual order for the same type of general commodities, resulting in excessive paperwork and labor costs. Now anytime that an individual Storekeeper needs to order more general commodities the other two Storekeepers are consulted and one Amutual (M.O.S.) order is submitted. During 2002 a total of 79 M.O.S. orders were written, resulting in an estimated order processing cost savings of $7,900. The table below represents the accomplishments of the M.O.S. for the first three years of the programs existence.

Year 2000 2001 2002 Grand Totals

Total M.O.S. Orders Written 56 73 79 208

As a result of the three-year existence of the M.O.S. there has been an estimated total order processing cost savings of $20,800. This estimate is based on an estimated order processing cost of $100 per order written.


Shipments & Parcels Received During 2002 the Inventory Control staffs at the Metro, Oak Orchard & Ley Creek Storerooms received shipments and parcels designated for virtually every section of the Department. For each shipment that is received the receiving process includes, all documentation involved, the notification of the employee that ordered the material, temporary storage until the shipment is picked up by the employee that ordered the material and in some cases the arrangement for and the actual delivery of shipments to the designated ordering section or employee. The following table indicates the number of shipments and parcels that were received by each storeroom during 2002.
