The Mni Wiconi Water Treatment Plant Coreline, operational since May 2002, is dedicated to enhancing the quality of drinking water, public health, and providing employment opportunities in the region. Serving a vast area of ten counties in central and southwest South Dakota, it is recognized as the largest Native American Tribal Water System in the United States.

This wholesale operation sources its water directly from the Missouri River and chemically treats it before distribution. The system supplies water to three Tribal Reservations and one non-Tribal entity, with individual systems managed by the Oglala Sioux, Lower Brule Sioux, Rosebud Sioux, and West River Lyman-Jones Rural Water Systems.
