The community of Frazer is located within the southwest corner of the Fort Peck Indian Reservation along U.S. Highway No. 2. Approximately twenty (20) miles West of Wolf Point and a twenty-nine (29) miles East of Glasgow within Valeyt County. Frazer has 115 service connections, 3- churches, community centers, Head Start, playground, Tribal ceremonial/pow-wow grounds, uses approximately 65,000 gallons of water per day. The water is pumped from four well sources within the community. Frazer is sustained by farming, ranching and basic services. In addition, to the farmland and rangeland, there are some wetlands along the Little Porcupine creek on the west edge of Frazer. The original water system was designed and constructed in 1968, and consisted of a well, pump house, controls, water distribution system(4 " watermains), and a storage facility. The storage facility consists of an 75,000 gallon elevated tower. The pump house has a chlorinator system that was installed 1992, upon b acteriological contamination. The chlorinator systemconsists of a 50 gallon solution tank, a positive-displacement pump with back pressurerelief/anti-syphon valve. The chlorine unit, is a metering pump that can be regulated between internal and external pulsing by means of a switch with frequency control knob. The pump drive is totally encapsulated in a chemical resistant housing to provide for maximum protection against chemical spillage. Chemical metering pump valves are ball check valves seated on combination valve seat and seal ring, that are routinely checked and replaced as they get worn. The four fucntion valve provides protection against chemical overloading and spillage, with negative pressure at discharge closing the diaphragm and preventing syphoning. The pressure relief function de-pressurizes the discharge line preventing chemical overpumping and possible line ruptures. |
