Key Points

Congress is considering a bill to study the possibility of building a large water system to serve parts of South Dakota, Iowa, Nebraska, and Minnesota. This project would provide water to homes, farms, and businesses in these four states.
The Department of the Interior would work with a local non-profit group to see if the project is realistic and meets federal standards. This is a first step to determine if a permanent water pipeline system can be built in the region.
The bill authorizes $10 million for the study. The federal government would pay for no more than half of the study's total cost, meaning local or state partners would need to cover the other 50%.
This study is intended to address the long-term need for reliable water in rural and industrial areas. The authority to conduct this study would last for 10 years after the bill becomes law.
