No offeror will be denied the opportunity to submit a proposal in response to the RFP. Utility Systems being privatized are described as follows: Dobbins ARB -- Electric Distribution System: Dobbins ARB receives electricity from Georgia Power Company (GPC) via the Lockheed Substation (Owned and operated by Lockheed Martin). The power from the substation enters the base via one of two feeders and is distributed over the government-owned equipment. The nominal distribution voltage to Dobbins from the substation is 12.47 kV Delta. The voltage is regulated to 11.97 kV at the point where Dobbins ARB takes over ownership. The majority of the government owned distribution feeder is overhead, although there are several areas of underground power. The typical phase conductors used for the underground lines is #4/0 AL in conduit. A government-owned, electronically controlled 3-shot circuit recloser and regulator bank is located on base. The recloser provides the main feeder fault protection for the system. Further protection on the system is provided by either fused cut-out or gang-operated switching devices at various locations on the base. The FY 98 total annual consumption was 19,608,557 KWH, while the average daily consumption was 53,722 KWH. There is over 23 wire miles of overhead primary conductor, installed around 1952. There is over 17,000 LF of underground primary conductor. Two-thirds of the underground system was installed in 1970, and one-third in 1998. Power is measured at 23 locations other than the master meter for reimbursable tenant organizations. Natural Gas Distribution System: Natural gas is currently supplied to Dobbins Air Reserve Base by Atlanta Gas Light Company (AGLC). AGLC mains are extended to five metering and regulator stations on the base where the pressure is regulated down to approximately 5 psi for distribution. A 6-inch interruptible service main provides gas to several buildings on the main base, including the central heating plant. A 4-inch non-interruptible service main runs to the west, following the north fence line. From this main, a valved 4-inch branch line is extended north. This 4-inch branch line was recently extended in a northwest direction. The branch again splits into a 1 -inch line and a 3-inch line. The 3-inch line is split to form a 2-inch loop serving several buildings. The 4-inch main also proceeds west until it further splits into two, 2-inch lines. A 2-inch non-interruptible main serves several buildings on the main base, including the dining hall. A single metering/regulator station is located to the south of the main gate. Another 2-inch non-interruptible main from this station serves several buildings. There is also a new 6-inch main that serves the southeast side of the base. The piping for the entire system is a mixture of both PE and steel. The annual consumption for 1998 was 39,166 MCF. There is over 16,000 LF of piping. Much of the system has been upgraded in the past 10 years, and thus is PE. However, there are still steel pipes 50 or more years old in the system. Water Distribution System: Dobbins ARB purchases potable water from the Cobb-Marietta Water Authority (CMWA). A 16-inch steel water main is metered north of AFP No. 6. Lockheed Martin acts as a secondary purveyor. The 20-inch steel water main from Lockheed Martin enters the base from the north near the Base Civil Engineer complex at which point Lockheed Martin meters the water supply. Total average daily usage is 89,500 gallons per day (gpd). The main from CMWA supplies approximately 51,400 gpd, and the main from Lockheed Martin supplies approximately 38,100 gpd. Delivered water pressure from the CMWA is at an average of 110 to 120 psi, but pressures can be as high as 150 psi. Water is distributed throughout the ARB through a 56,000 LF looped supply system. The water distribution system consists of mostly of cast iron pipes ranging in size from 2 to 16 inches in diameter. Most of the system was originally constructed between 1954 and 1956. Recent upgrades have replaced portions of the old cast iron pipes with polyvinyl chloride (PVC) piping. Backflow preventers are present in the system. There are no pump stations, wells, storage tanks or treatment facilities located on the base. The fire protection water system is excluded from the potable water distribution system for the purposes of this privatization study. The Air Force will retain ownership and responsibility of the fire water system due to the critical relationship of this system to the mission of Dobbins ARB. Any dedicated systems related to fire flow, including distribution pipes, storage tanks, and pump stations are not considered part of the water distribution system for utility privatization. Wastewater Collection System: The Dobbins Air Reserve Base has a sewage collection system that serves the majority of the site. Two remote areas are served by septic tank systems with drainfields. Gravity sewer lines, pump stations, and force mains transport the majority of sewage to the Lockheed Martin wastewater treatment plant located at AF Plant No. 6. Lockheed Martin leases and operates AF Plant No. 6. Sewage flow from the main base is not metered. Billings are based on water usage. Assuming a water usage of 89,500 gpd in 1998 and a theoretical ratio of 70% of the potable water reaches the sewer, sewage flow can be estimated at 62,200 gpd. Domestic sewage is collected throughout the Dobbins ARB through underground pipelines, ranging in size from 4 inches, for house or building connections, to 10 inches for the main sewer connections. Much of the system is 45 years old. Original pipe materials of construction mainly included vitrified clay. Later expansions used concrete and PVC. The current predominant pipe material is vitrified clay. Overall, there is an estimated 47,035 linear feet of sewer pipe and force mains and 146 manholes. There are 6 pump stations on the base. Dobbins ARB treats its oily wastewater using oil/water separators. According to base personnel there are 16 oil/water separators on site. Discharges from the oil/water separators go either to the sanitary sewer or to the storm water drainage system. At this time the Air Force maintains the systems. NAS Atlanta -- Electric Distribution System: Naval Air Station Atlanta receives electrical power from Georgia Power Company (GPC) via the GPC Substation (owned and operated by GPC). The GPC substation is located on the NAS Atlanta property immediately adjacent to NAS Atlanta's Main Switching Station and is supplied from a radial tap off of a 46 kV distribution line. Approximately 1,300 LF of overhead electrical distribution was upgraded in 1999 with new poles, conductors, transformers, etc to include the installation of a new neutral wire. The base also installed a new S&C pad-mounted switch containing two (2) 600 Amp load interrupting switches and three (3) 600 Amp vacuum interrupters rated at 13.8 kv Nominal, 95 kV BIL, 12.5 kA symmetrical interrupters. The load interrupting switches are Kirk-key interlocked to allow transfer from the utility source to the 200 kW generator system. Georgia Power Company also installed one (1) new 5.25 MVA three phase transformer to replace the old 833 kVA transformers. Power on the base is typically distributed across NAS Atlanta via three radial 12.47 kV feeders. With the exception of the new equipment discussed above, typical construction methods for the Pole Line Circuit is overhead routed #4 AWG solid copper conductors on either conventional wood pole/wood cross-arm structures or concrete poles with insulated stand-off devices with no static wire or neutral. The transformers are double bushing type connected line-to-line, and lightning arresters are rated at 15 kV. Typical construction methods for the Hangar and Pump House Circuits consist of underground (1/0 AWG copper) conductors in conduit. The FY 98 total annual consumption was 9,202,283 KWH, while the average daily consumption was 25,212 KWH. Except for the 1999 upgrade, there is 7 wire miles of overhead primary conductor installed around 1959. There is approximately 2,500 LF of underground primary conductor which was also installed in 1959. Natural Gas Distribution System: Natural gas is currently supplied to Naval Air Station Atlanta by the Atlanta Gas Light Company (AGLC). AGLC mains are extended to two metering and regulator stations on the base where the pressure is regulated down to approximately 5 psi for distribution. The primary gas metering station is located on Navy property. From this station, gas is piped via a 6-inch pipe extending north to the central plant. From the central plant, the line has been extended further east, to where a number of buildings along this run have been added to this main. Other mains have been extended from the 6-inch main to the west, serving many of the station's industrial and residential sites. A separate line extends from the primary metering station to the northwest. A second metering station is located on the southern portion of the base. The main from this station extends to the north, serving a number of facilities. The piping for the entire system is original steel installed in 1959. The annual consumption for FY 1998 was 17,633 MCF. There is over 13,000 LF of piping. Water Distribution System: NAS Atlanta does not own or operate a potable water treatment plant. All potable water is purchased from public water systems. There are several separate service connections to various suppliers depending on the geographic location being served. NAS Atlanta Main Base purchases its potable water from the Cobb Marietta Water Authority (CMWA). Both NAS and the CMWA read water meters monthly. For a 12-month period from November 1997 to October 1998 the total average monthly usage was 1.34 million gallons per month, or 44,000 gpd. The peak monthly usage during this period was 1.74 million gallons per month (57,200 gpd). Delivered water pressure from the CMWA is at an average of 60 to 63 psi. Service is provided through one 16-inch diameter line connecting at a master meter. NAS has no onsite elevated water storage and derives its water pressure from the CMWA system. NAS has a combination of a looped distribution system (serving some administrative buildings, temporary living quarters, and family housing) and an unlooped distribution system (serving other service buildings and the hangar areas). The largest potable water line is 16 inches in diameter, with most of the other piping consisting of 6- and 8-inch diameter lines. There are reportedly 61 existing backflow preventers at NAS Atlanta. These backflow preventers are tested annually. There is an existing 750,000-gallon water storage tank that is part of the system. It is utilized for storage for fire protection. Except for approximately 1,000 LF of PVC, the entire 21,000 LF water system is cast iron piping installed in 1959. Wastewater Collection System: Naval Air Station Atlanta has both domestic sanitary sewage and industrial wastewater collection systems. Sanitary Sewage: NAS Atlanta has a domestic sewage collection system that serves the entire base. The sewage is taken by gravity sewer lines, pump stations and force mains and is discharged into the off-site Air Force Plant No. 6 central treatment plant operated by Lockheed Martin Aeronautical Systems Company. NAS Atlanta has no sewage treatment equipment. Billings from Lockheed for sewage service are based on water usage. Average daily sewage flow at the main base is estimated at about 30,800 gallons per day (gpd) based on 70% capture of the potable water usage of 44,000 gpd (for the period from November 1997 through October 1998). Actual sewage flows may be higher depending on the contributions from inflow and infiltration. Domestic sewage is collected throughout NAS Atlanta through underground pipelines, ranging in size from 4 inches for house or building connections, to 8 inches for the main sewer connections. Most of the system is about 40 years old. Original pipe materials of construction included vitrified clay. Newer improvements include concrete and PVC. The 13,500 LF system was installed in 1959. Industrial Wastewater: NAS Atlanta has an industrial wastewater collection system separate from the domestic sewage system. Collection pipes sizes go up to 21 inches in diameter. There are two industrial wastewater pump stations. The collection system mainly collects oily wastewater and pumps it to the industrial wastewater treatment facility operated by Lockheed Martin off the NAS Atlanta property. Industrial flow is metered and averages about 56,000 gpd. The industrial wastewater flow rate includes rainwater infiltration at two existing aircraft washracks. The 7,144 LF system was installed in 1959. Windy Hill USMC Site -- Electric Distribution System: NAS Atlanta maintains the Windy Hill Marine Corps Site, a 27-acres US Marine Corps Training Site located south of NAS Atlanta in the town of Smyrna, Georgia. NAS Atlanta owns, operates, and maintains some electrical distribution equipment at this location. The electrical power to the Windy Hill Site is supplied by GPC via a metered drop from a radial feeder. The electrical equipment at Windy Hill consists of two pad-mounted transformers and associated underground primary/secondary conductors to feed the eight buildings and communications towers at the site. Total annual consumption for FY 1998 was 262,800 KWH. Average daily consumption is 720 KWH. Water Distribution System: NAS Atlanta maintains the Windy Hill Marine Corps Site, a 27-acres US Marine Corps Training Site located south of NAS Atlanta in the town of Smyrna, Georgia. The Windy Hill Marine Corps Site is under contract with the City of Smyrna for potable water service. Water meters consist of the main and bypass meters. For a 12-month period from November 1997 to October 1998 the total average monthly usage was 12,400 gallons per month (407 gpd). The peak monthly usage during this period was 36,000 gallons per month (1,180 gpd). There is approximately 1,500 LF of piping. Wastewater Collection System: NAS Atlanta maintains the Windy Hill Marine Corps Site, a 27-acres US Marine Corps Training Site located south of NAS Atlanta in the town of Smyrna, Georgia. Sewage at the Windy Hill Marine Corps Site is collected and discharged to the City of Smyrna for domestic wastewater treatment. Sewage flow is not measured at Windy Hill. Billing is based on water usage. Sewage flow is estimated at 280 gpd based on 70% of the average water usage. There is approximately 1,850 LF of piping. This requirement is unrestricted.
