Thune, Rounds Legislation to Advance Key South Dakota Water Projects Approved by Committee

FOR IMMEDIATE RELEASE June 10, 2026
WASHINGTON — U.S. Sens. John Thune (R-S.D.) and Mike Rounds (R-S.D.) today applauded the Senate Committee on Energy and Natural Resources for passing their bills that would authorize feasibility studies for the Western Dakota Regional Water System (WDRWS) and the Dakota Mainstem Regional Water System, respectively. Thune’s Western South Dakota Water Supply Project Feasibility Study Act (S. 3723) and Rounds’ Dakota Mainstem Water Supply Project Feasibility Study Act (S. 3736) now head to the full Senate.
“These bills are aimed at addressing the rapidly growing water needs in rural communities across South Dakota,” said Thune. “I’m pleased that the committee has passed our bills and look forward to their consideration by the full Senate. I’m proud to work with Senator Rounds on this critical effort.”
“Rural water projects are crucial for the success of South Dakota, both in the near future and for the next generation,” said Rounds. “I’m pleased that the Senate Committee on Energy and Natural Resources has passed our bills to authorize feasibility studies for the Dakota Mainstem Regional Water System and the Western Dakota Regional Water System. I thank Senator Thune for his leadership on this issue and look forward to working together to get these bills through the full Senate.”
“The advancement of S. 3723 to Senate markup is an encouraging step forward for the future of water security in western South Dakota,” said Kristin Conzet, executive director of WDRWS. “WDRWS is grateful for the leadership and diligent work of Senators Thune and Rounds, whose commitment has been instrumental in advancing our legislation. Reaching this stage reflects growing recognition of the need for a reliable, long-term water supply to support our communities, economy, agriculture, and national defense interests.”
“On behalf of the Dakota Mainstem Regional Water System and our 57 member water systems, I want to thank Senators Rounds and Thune for their leadership and continued support of this important authorization,” said Ryan Johnson, president of the Dakota Mainstem Regional Water System. “Advancing S. 3736 through the markup process is a significant milestone that moves Dakota Mainstem one step closer to the feasibility study phase with Bureau of Reclamation participation. We are grateful for the senators’ commitment to strengthening water infrastructure and helping ensure a reliable water future for the communities, businesses, and residents we serve.”
