Doyon Utilities - JBER

JBER Richardson is located in the Municipality of Anchorage, Alaska. The cantonment area covers approximately 7,000 acres. JBER Richardson’s population consists of approximately 6,500 authorized military personnel, 2,941 family members, 1,765 Army retirees, and 1,282 civilians. Family housing on the post totals 1,261 units.

Electrical Distribution System (EDS). The JBER Richardson Electrical Distribution System consists of the decommissioned Central Heat and Power Plant (CHPP), switchgear, transformers, overhead and underground distribution circuits, poles and duct banks, vaults, switches, and street lighting. Doyon Utilities and the local base DPW staff are looking to re-power this decommissioned CHPP plant with adjacent landfill gas and/or biomass and/or MSW over the next 5 years.

The distribution system is a combination of overhead and underground power circuits. Overhead circuits comprise approximately 100 circuit miles and serve the majority of the Post, while underground circuits comprise approximately 9 circuit miles and serve the headquarters area and some of the housing areas. Doyon Utilities is required under the utility privatization contract to fully reconstruct the electrical distribution system over the first 5 years.

Natural Gas Distribution System. The JBER Richardson Natural Gas Distribution System consists of: distribution mains, regulators, valves, and meters. The overall JBER-owned gas system is fragmented into eight independent sub-systems that are not interconnected. The JBER natural gas system was installed between 1977 and 1985 and consists mostly of 2-inch DRISCO pipe. The JBER natural gas system consists of approximately 65,070 lineal feet of pipe and provides natural gas to approximately 50 facilities located oN JBER.

Potable Water Distribution System. The JBER Richardson Potable Water Distribution System consists of: wells, treatment equipment, storage tanks, pumps, ancillary structures, fire hydrants, valves, meters, and piping. In addition to supplying potable water to JBER Richardson, the JBER Water Treatment Plant also supplies potable water to JBER Elmendorf and raw water to the State of Alaska fish hatchery on JBER. At the present time, there is no interconnection between JBER and the Anchorage Water and Wastewater Utility. JBER has two raw water sources: one source is diversion of water from Ship Creek reservoir and the other are three wells located on JBER. The water treatment plant receives raw water from Ship Creek Dam via a 20-inch water line. The JBER water treatment plant is a conventional water treatment plant that employs the treatment processes of coagulation, flocculation, sedimentation, filtration and disinfection. The treatment processes are housed in one building except for the disinfection system housed in two separate structures near the treatment plant. The rated capacity of the water treatment plant is 7.0 mgd. The maximum plant treatment production was 5.9 mgd in August 1997. There is one 2,500,000 gallon concrete underground storage tank. The potable water distribution system consists of 44.7 linear miles of pipe within the system, typically installed to a depth of 10 feet.

Wastewater Collection System. The JBER Richardson Wastewater Collection System consists of: lift stations, manholes, force mains, and gravity piping. All wastewater generated on JBER is collected and transferred to the City of Anchorage Water and Wastewater Utility (AWWU) for treatment. The wastewater collection system consists of pipe with an approximate total installed lineal extent of 29.2 miles.
