West River/Lyman Jones is a private, non-profit corporation formed for the purpose of providing rural water to its membership.

WR/LJ is one of four sponsor systems included in the Mni Wiconi Water Supply Project. The Mni Wiconi Rural Water Supply Project was authorized by Public Law 100-516 on October 24, 1988 to provide a safe and adequate municipal, rural and industrial water supply to West River/Lyman-Jones, the Oglala Sioux Rural Water Supply System, the Rosebud Sioux Tribe Rural Water System and the Lower Brule Sioux Tribe Rural Water System. It took countless individual contributions and a great cooperative effort among tribal and non-tribal members to turn this “pipe dream” into a reality.
