Water Treatment facility



Drinking Water Quality

Information about the quality of Pierre’s current drinking water is available in the City’s annual drinking water report.

The Background

The City of Pierre began looking into treated water options following a community survey. The results show the majority of respondents thought the City should consider constructing a water treatment facility to combat the high mineral content found in Pierre’s current water supply.

AE2S, an engineering consulting firm, was hired to study Pierre’s water system and its options for treating water. AE2S recommended the City build a more than $37 million water treatment plant just south of the Missouri River highway bridge.   

The Decision

The Pierre City Commission put the project to a public vote in June of 2018. The project passed with 73% of the vote.

In July 2020, the City Commission approved the facility design and project cost .

Current Water 

Currently, Pierre’s water is obtained from a series of wells located throughout the City. Water is treated at the wellhead and pumped to reservoir storage units for distribution throughout the community.

The City of Pierre Water Department pumps and treats up to 5.5 million gallons of water each day.
