SIOUX FALLS, S.D. (WNAX)- The hot dry summer has focused the need for a more reliable water source for many of the towns and cities in southeast South Dakota including Sioux Falls.

The Lewis & Clark Regional Water System already provides water to many of those towns. Executive Director Troy Larson says they are expanding their water sources.

Larson says this summer put a lot of stress on their system.

Larson says they have the capacity to pump and treat more water.

Larson says they are hoping that infrastructure funding at the state and federal level can help fill the final one hundred thirty million dollars needed to finish the project.

Wells near the Missouri River south of Vermillion supply the system that delivers water to towns and cities in South Dakota, Iowa and Minnesota.
