Decoded
What does this do?
This bill would require a study to find out whether building a new water supply project in parts of South Dakota, Iowa, Nebraska, and Minnesota is practical and affordable. The study would look at serving cities, towns, rural areas, and businesses in that region. The authority to conduct the study would expire ten years after the bill becomes law.
Who does it affect?
The U.S. Secretary of the Interior would lead the study, working together with the Dakota Mainstem Regional Water System, a nonprofit organization.
Why does it matter?
Without a feasibility study, it is not known whether a regional water supply project in this area is practical or affordable. This study would produce information that could inform future decisions about water infrastructure in the region.
What does it cost, and who pays?
- Up to $10M in federal funding
- Federal covers max 50% of study cost
- Remaining cost on Dakota Mainstem
