S -- PRIVATIZATION OF THE ELECTRIC, WATER AND WASTEWATER UTILITY SYSTEMS AT FORT STEWART AND HUNTER ARMY AIRFIELD, GEORGIA SOL SP0600-99-R-0011 DUE 030499 POC Elizabeth Pesenti, Contracting Officer (703)767-8130 E-MAIL: For additional information or clarification., epesenti@desc.dla.mil. Privatization of the electric and water utility distribution systems and wastewater collection systems at Fort Stewart and Hunter Army Airfield, Georgia. Privatization will transfer to the private sector the responsibility for the ownership, operation, maintenance, and repair of the Government-owned utility systems for electric, water and wastewater services. All applicable State and Federal laws and regulations must be complied with. Fort Stewart's electrical distribution system consists of a cantonment area main substation that is a two-unit substation (30 MVA each) served at 115 kilovolts (kV), located in the housing area on Hero Road. The two transformers in the main substation and associated equipment the primary side, are owned and maintained by Georgia Power Company and maintained in a separate fenced lot. The adjacent distribution feeder portion of the substation contains the Fort Stewart 25 kV distribution equipment. The substation 25 kV buswork is overhead serving 8 padmounted oil circuit breakers (7 active, 1 spare). There is a 12.47-25 kV step-up transformer bank near Evans heliport. The step-up transformers and 25 kV distribution are owned and operated by Fort Stewart. There is one 25 to 4.16 kV step-down substation (at the energy plant). There are approximately 37 circuit miles of overhead primary distribution, and approximately 37 circuit miles of underground primary distribution. There are approximately 9000 street lights (mercury vapor, high-pressure sodium; low-pressure sodium, and metal halide). Fort Stewart also has primary metering equipment (on each side of the National Guard Training Area). The distribution system serves approximately 2061 buildings located throughout the installation. The Hunter Army Airfield electrical distribution system consists of, but is not limited to: a cantonment area main substation. The substation is a two-unit substation (7.5/10.5 MVA each) served at 46 kilovolts (kV) located on Hunter Army Airfield. The two transformers in the main substation and associated equipment the primary side are owned and maintained by Savannah Electric Power Company and maintained in a separate fenced lot. The adjacent distribution feeder portion of the substation contains the Hunter Army Airfield distribution 13.8 kV distribution equipment. The substation 13.8 kV buswork is overhead serving 10 padmounted oil circuit breakers (9 active, 1 spare). The airfield substation is a 13.8-4.16 kV substation with one incoming 13.8 kV line, four 667 kVA transformers (one spare), and two 4.16 kV circuit breakers. There are approximately 28 circuit miles of overhead primary distribution, and approximately 8 circuit miles of underground primary distribution. There are also approximately 2900 streetlights. The electrical distribution serves approximately 662 buildings located throughout the installation. Fort Stewart's main water system consists of approximately 101 miles of water main line (less than 2 inches to 16 inches), approximately 620 main valves, approximately 170 building service valves, approximately 6 main meters, three ground storage tanks, four elevated storage tanks, and approximately 830 fire hydrants. Fort Stewart's raw water supply sources include ground water pumped from onsite wells and potable water supplies provided by the City of Hinesville. Approximately 16 water wells are being utilized. Ground water is pumped from these wells and chlorinated at the well head prior to being sent to the storage tanks. There is no potable water treatment plant at Fort Stewart. The distribution system handles an average daily flow of approximately 1 million gallons per day. The wastewater collection system consists of approximately 56 miles of sewer mains ranging from less than 4 inches to 30 inches in diameter. The wastewater treatment facilities consists of 27 pump stations, Evans Airfield package treatment plant (35,000 GPD), TAC-X package treatment plant (35,000 GPD), Camp Oliver land application site (60,000 GPD, two lagoons with irrigation spray system), Wright Army Airfield land application site (8,000 GPD and 1.25 acres Oxidation Pond), and approximately 1,154 manholes. Hunter Army Airfield's potable water distribution system consists of approximately 33.3 miles of water main line (less than 2 inches to 12 inches), approximately 352 main valves, five elevated storage tanks, and approximately 288 fire hydrants. The raw water supply sources include ground water pumped from on-site wells. Approximately nine active water wells are being utilized. Ground water is pumped from these wells and chlorinated at the well head prior to being sent to the storage tanks. There is no potable water treatment plant at Hunter Army Airfield. The distribution system handles an average daily flow of approximately 330,000 gallons per day. The wastewater system consists of a collection system, lift stations, emergency generators, and central treatment works. Most of the wastewater generated is treated at the central treatment plant. There are approximately 24 miles of mains (less than 4 inches to 24 inches), and 400manholes within the collection system. Approximately two-thirds of the sewer lines are 8 inches. There are 14 lift stations within Hunter Army Airfield. There are two emergency generators associated with two lift stations located at the family housing area and north side of the post. The central wastewater treatment plant is an activated sludge plant with a rated capacity to treat 1.25 million gallons per day. The average loading for FY 96 of the sewage treatment plant was approximately 650,000 GPD. This requirement is unrestricted.
