Why It Matters
South Dakota communities that depend on aging aquifer systems for drinking water could eventually gain access to a more reliable Missouri River supply if federal feasibility studies move forward. The Senate committee action this week marks a significant step toward determining whether two large-scale regional water pipeline systems are viable.
What Happened
The Senate Committee on Energy and Natural Resources voted Wednesday to advance a pair of bills sponsored by South Dakota’s two Republican senators, John Thune and Mike Rounds. The measures would direct $20 million to the Bureau of Reclamation to conduct feasibility studies on two separate regional water pipeline projects drawing from the Missouri River.
Both bills cleared the committee on a voice vote, with no opposition recorded among the 13 bills the panel considered that morning. The funding is designated strictly for study purposes and does not authorize pipeline construction.
One bill would fund a $10 million study of the Western Dakota Regional Water System, a proposed pipeline that would carry Missouri River water to communities in western South Dakota currently relying on aquifer sources. The second bill would direct another $10 million toward studying the Dakota Mainstem Regional Water System, which would extend service to eastern South Dakota, western Minnesota, and parts of northern Iowa.
By the Numbers
- $20 million in total federal funding approved for feasibility studies
- $10 million allocated per individual pipeline study
- 2 regional water systems under consideration
- 13 total bills considered by the energy committee Wednesday
- 0 votes in opposition — both measures passed on voice vote
Zoom Out
Water supply reliability is an escalating concern across the Great Plains and Mountain West, where communities increasingly face pressure on groundwater reserves. Federal feasibility studies through the Bureau of Reclamation are typically a prerequisite before Congress authorizes and funds infrastructure construction, making this funding an early but essential stage in a longer process.
The House side of the effort is being carried by South Dakota’s lone House member, Rep. Dusty Johnson, who introduced companion legislation. Those bills received hearings in April before the House Natural Resources Subcommittee on Water, Wildlife and Fisheries and are awaiting a vote by the full committee. Similar infrastructure investment interest has surfaced elsewhere in South Dakota, reflecting broader momentum around long-range energy and water resource planning in the state.
What’s Next
With Senate committee approval secured, the two bills will need to advance to the full Senate floor for a vote before they can be sent to the president for signature. On the House side, Johnson’s companion bills must clear the full Natural Resources Committee before proceeding further. If both chambers pass their respective versions, a conference process would reconcile any differences before final passage.
Assuming the legislation is enacted, the Bureau of Reclamation would then conduct the authorized feasibility studies — a process that typically takes several years — before any construction decisions could be made. South Dakota lawmakers have pursued several infrastructure and fiscal policy priorities in the current congressional session, with water supply security emerging as a key long-term concern for rural communities across the state.
