Water supply: systems; mobile home park water delivery systems; regulate. Amends secs. 2, 5 & 10 of 1976 PA 399 (MCL 325.1002 et seq.).

This bill amends the Safe Drinking Water Act in Michigan to update and clarify the definitions of various terms used throughout the law. It directly affects water suppliers, public water systems, and mobile home parks by refining how they are categorized and regulated. Key changes include redefining concepts such as "community supply," "nontransient noncommunity water supply," and "public water supply" to better align with current service levels and operational realities. Additionally, the legislation clarifies specific technical definitions like "customer site piping" and "source water assessment" to ensure consistent application of state drinking water standards.
