Mission: Quality water for southwest North Dakota
Vision: People and business succeeding with quality water

The Southwest Water Authority (SWA), a political subdivision, was established by the North Dakota State Legislature in 1991. SWA is governed by a 15-member board of directors representing the following counties: Adams, Billings, Bowman, Dunn, Golden Valley, Grant, Hettinger, Mercer, Morton, Oliver, Slope and Stark, the cities of Dickinson and Mandan.

The Southwest Pipeline Project (SWPP) is state owned and administered by the North Dakota State Water Commission (SWC). The SWPP transports raw water from Lake Sakakawea to the Dickinson WTP, the Southwest WTP and the OMND WTP where it is treated and delivered to the project’s customers in southwest North Dakota and Perkins County, South Dakota. SWA is responsible for the management, operations and maintenance of the Project.
