Water supply: systems and utilities; reporting requirements for certain utilities; provide for. Creates new act.

HB 5172 requires water, sewerage, and stormwater management providers in Michigan to file annual reports with the Department of Health and Human Services. These reports must include detailed information on rates, charges (like late fees or connection fees), billing practices, asset management, customer categories, and financial data such as arrears, foreclosure actions, and capital improvement funding sources. The bill directly affects all providers offering these services to retail or wholesale customers, including both governmental and nongovernmental entities. The goal is to increase transparency about utility pricing and operations, with providers reporting specific metrics like metering practices, billing frequency, and revenue breakdowns.
