The City of Fort Pierre currently purchases water from the West River/Lyman Jones Rural Water System and resells water to its customers. The City of Fort Pierre has recently been notified by its drinking water source provider that in 2032, this provider will no longer be able to provide Fort Pierre with drinking water. Consequently, the City of Fort Pierre is proposing to construct a new drinking water intake and treatment facility to address this drinking water source issue.

The City’s 2022 Drinking Water Intake and Treatment System Study included two (2) engineering alternatives to the City’s drinking water facility:

1. Alternative 1 includes utilization of a caisson intake of surface water from the Missouri River.
2. Alternative 2 includes utilization of a slanted tube style intake of surface water from the Missouri River.

Both alternatives will account for future zebra mussel control via chemical feed system and brass intake screen. Both alternatives also include a water treatment building and process. The project includes a treated water main line to connect the new intake/treatment facility to the City’s existing water distribution system and storage tanks.

Both project alternatives place the new treatment facility in an area in the center of Fort Pierre near the Missouri River on City owned property just south of the Railroad Bridge.  Both alternatives sited the new intake in the proposed location because it allows for dependable inflow into the Fort Pierre system from the Missouri River at a deep point in the channel.

Potential funding for the project costs includes a loan through the State Revolving Loan Fund (SRF) and grant funds.  The City of Fort Pierre also anticipates utilizing ARPA (SLRF) funds towards this project to reduce the amount of the loan. The Loan for this project will be paid by a monthly surcharge passed on to our estimated 1250 system users.
