Sioux Falls Expands Water Supply With New Well Now Operational

The City of Sioux Falls has officially placed the newly reconstructed Well into service in the city’s ongoing efforts to secure a reliable water supply.

Located on the north side of Sioux Falls near the Big Sioux River, Well 25 is a critical part of the city’s groundwater system.

The newly upgraded well can provide more than 5 million gallons of water per day, with peak production reaching up to 7 million gallons daily.

The water is delivered to the city’s purification plant before being distributed to homes and businesses throughout the community.

City officials say the new well will help meet increasing demand as Sioux Falls continues to grow.

The additional capacity will support residential, commercial, and industrial development while helping maintain dependable service during periods of high summer water use.

The project replaces a well originally built in 1952 that served the city for more than seven decades.

Engineers transformed the site into a modern horizontal collector well featuring six horizontal laterals extending a combined 700 feet into the aquifer.

This design increases the collection area and improves long-term groundwater production while helping protect the aquifer’s sustainability.

The $9.3 million project was completed in two phases and received significant support through a federal grant administered by the South Dakota Department of Agriculture and Natural Resources.

Construction began in 2023, with planning, testing, and development spanning several years.

Well 25 is one of several infrastructure improvements planned by Sioux Falls to ensure safe, reliable drinking water service and provide the capacity needed to support the city’s continued growth for years to come.
