Lewis & Clark Regional Water System (L&C), a non-profit corporation composed of numerous municipalities and rural water systems, is constructing a water supply pipeline and associated well field, pump stations, treatment plant, and storage reservoirs throughout southeastern South Dakota, southwestern Minnesota, and northwestern Iowa. The overall pipeline runs from a newly developed well field beside the Missouri River in southeastern South Dakota to various existing water systems connection points located throughout the region. The completed pipeline system would be approximately 400 miles long, and pipeline diameters range from 6 to 54 inches. The project will provide a high-quality reliable domestic water supply to residents of 14 counties in southeastern South Dakota, southwestern Minnesota, and northwestern Iowa. To date, construction is estimated at 78% complete, with the water treatment plant, the raw water pipeline, the well field, several miles of treated water pipeline, several water reservoir towers, pump stations, and meter buildings having been completed. Banner Associates is currently completing the wetland delineation for the Madison Service Lines- Segments 2, 3, and 4, and will be incorporating that information into a biological survey report for the project.
