The bill, enacted as R.S. 33:4081.1, establishes regulations for municipalities regarding the replacement of lead service lines in municipal water systems. It allows municipalities to adopt ordinances that grant them or their agents the right to enter private properties to perform lead service line replacements, provided they give at least seven days' notice to property owners and residents, except in emergencies. The bill outlines specific notice requirements, including attempts to inform residents in person, sending certified mail, or posting written notices on the property. Additionally, municipalities must inform property owners post-replacement about the work completed.

Furthermore, the bill defines key terms such as "municipal water system" and "service line," clarifying the scope of the legislation. It also stipulates that the provisions will only take effect if the Louisiana Constitution is amended to permit the use of public funds for identifying, inventorying, and replacing drinking water service lines that are hazardous, including those made of lead. This legislation aims to enhance public health and safety by addressing lead contamination in drinking water systems.
