History of ASRWSS

In 1992, the Fort Peck Tribes decided that the water problems on the reservation had to be addressed and began work on a water supply system for the southern half of the reservation. It was soon realized that if all the people on the reservation couldn't benefit from the system, federal funding would be difficult to secure.

In 1994, the system was redesigned to include the whole reservation with a one-phase construction plan to cut costs. It was then presented to Senator Conrad Burns who after study suggested it become a regional water system because areas outside of the reservation were experiencing similar water quality problems.

The Fort Peck Reservation Rural Water System Act of 2000 (Public Law 106-382; 114 Stat. 1454) was enacted in October, 2000.

Beginning in fiscal year 2001, funding for these projects was authorized to be appropriated over a period of 10 fiscal years. Method of awarding/releasing assistance: lump sum.

The Fort Peck (Assiniboine and Sioux) Reservation/ Dry Prairie Rural Water System is providing drinking water to 27,434 people in eastern Montana. American Recovery and Reinvestment Act of 2009 funding is being used to complete construction of the water treatment plant, and accelerate: rights-of-way acquisition, engineering design, and construction of project pipeline segments.

Funding of $39.8 million was provided to the Fort Peck Tribe on August 26, 2009. This funding is being used to install the following:

• Approximately 2 miles of the raw water pipeline from the intake structure to the Water Treatment Plant (WTP), is scheduled to be completed in the fall of 2010.

• Phase II of the WTP, is scheduled to be completed by May 2011.

• The WTP to Poplar pipeline; bids on this project were opened on June 15, 2010 and award of the project is scheduled for July 2010. The project is scheduled to be completed by September 2011.
