M -- MAINTAIN AND OPERATE THE HANFORD WATER SYSTEMS IN THE 200 AREA AND 100 AREA; AND IN THE CONSTRUCTION, MAINTENANCE, AND OPERATIONS OF A 200 AREA SANITARY SEWER SYSTEM DUE 062495. Contact Bernard L. Ayers, Contracting Officer, 509/376-8601. The U.S. Department of Energy, Richland Operations Office (RL), will be requesting expressions of interest from the water industry in providing potable and raw (untreated) water to the 200 Area, raw water to the Hanford 100N Area, and potable water to various small facilities. The potable water is used for drinking, process, and fire protection needs. The raw water is used for process and fire protection needs. The potential bidders could propose taking on all or a combination of the following: Operations of the water systems. Maintenance of the water systems. Reconfiguration of the existing system to suit Hanford needs which may require a capital investment. RL is also interested in requesting an expression of interest from the sanitary wastewater industry in providing sanitary wastewater services for the Hanford 200 Area. RL will consider proposals for construction, operation, and maintenance of a sanitary wastewater system in the 200 Area. Following are the technical aspects of the system: Water, Operations and Maintenance. The water systems will be required to be operated and maintained in accordance with the Federal Safe Drinking Water Act and the State of Washington Department of Health Drinking Water Regulations. Fire protection requirements of the National Fire Protection Agency (NFPA) and DOE Orders will have to be met. The physical systems consist of the following: Export Water System: 181-B Area River Pumphouse. 182-B Raw Water Pumphouse. 182-B 25,000,000 gallon above ground open reservoir. 181-D River Pumphouse. 182-D Raw Water Pumphouse. 182-D 25,000,000 gallon above ground open reservoir. Approximately 25 miles of reinforced concrete pipe ranging in size from 42 inches down to 24 inches in diameter. 200 East Water System: 283 East Water Treatment Plant. 282 East 3,000,000 gallon reservoir. Two (2) 200,000 gallon underground covered potable water reservoirs. Maximum rated flow of 2600 gallons/minute. Current population of 3385. 200 West Water Treatment System: 283 West Water Treatment Plant. 282 West 3,000,000 gallon above ground open reservoir. Two (2) 200,000 gallon underground covered potable water reservoirs. Maximum rated flow of 2600 gallons/minute. Current population of 2026. Small Water Systems: (serving populations between one to twenty-five people). 182-B Water System: Small packaged water treatment system. Rated capacity of 20 gallons/minute. 609 Fire Station Water System: Small packaged water treatment system. Rated capacity of 125 gallons/minute. 251-W Water System: Small packaged water treatment system. Rated capacity of 30 gallons/minute. Yakima Barricade Water System: Ground well with no treatment. Patrol Training Academy Water System: Ground well with no treatment. Operations: The Export Water System provides raw water to the 100N Area, 200 East Area, 200 West Area, and to several of the small water systems (182-B Water System, 609 Fire Station, 251-W). The large water systems treat the water and distribute it as potable water for drinking and process needs. The large water systems also distribute the raw water which is used for fire protection and process needs. The small water systems treat the water and provide only potable water to a single facility. Current population for the 200 East Area is 3,385, and 2,026 for the 200 West Area. The small water systems serve populations ranging from one to twenty-five. Population may decrease as a result of downsizing the Hanford workforce. Sanitary Wastewater: The Hanford 200 Area currently has approximately 80 subsurface absorption systems. Approximately five of the systems have failed and nine systems are close to failure. The sanitary wastewater system would have to be constructed, operated, and maintained in accordance with the State of Washington Department of Health Regulations. (131)
