Southwest Pipeline Project

NDCC, Section 61-24.3 declares necessary that the Southwest Pipeline Project established and constructed, to provide for the supplementation of the water resources of a portion of the area of North Dakota south and west of the Missouri River with water supplies from the Missouri River for multiple purposes, including domestic, rural, and municipal uses. The Water Commission has been working to develop the Southwest Pipeline ever since – with construction beginning in 1986. (NDCC 61-24.5 authorizes the Commission and Southwest Water Authority to construct, operate, and maintain the project.)

Southwest Pipeline serves a population of more than 58,000 people in southwest North Dakota in 33 communities, with over 5,575 rural service locations, 23 raw water customers, 28 contract customers including three crew camps and two raw water depots for the oil and gas industry. SWA also provides potable water to two rural water systems: Missouri West Water System in Morton County and Perkins County Rural Water System in South Dakota.

The Southwest Pipeline Project is operated and maintained by the Southwest Water Authority.
