Western South Dakota Water Supply Project Feasibility Study Act

This bill directs the Secretary of the Interior to conduct a feasibility study for a proposed water project supplying municipal, rural, and industrial water from the Missouri River to Western Dakota Regional Water System, Inc. (a nonprofit entity serving communities in western South Dakota). The study will assess whether the project should be built and determine the required non-Federal cost share (minimum 25% of construction costs), with the federal government covering up to 50% of the study’s $10 million cost. The study must include consultation with tribal, state, and local authorities, and the resulting report will be submitted to relevant congressional committees and made public. The bill does not authorize construction but sets the process for evaluating the project’s feasibility over a 10-year period.
