The bill enacts R.S. 33:4081.2, which establishes regulations for lead service line replacement by municipalities and their water systems in Louisiana. 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, the bill mandates that municipalities must inform property owners by certified mail after the completion of the replacement, detailing the time of the work and a summary of the actions taken. It defines key terms such as "municipal water system" and "service line" to clarify the scope of the legislation. Overall, the bill aims to enhance public health and safety by ensuring proper communication and procedures surrounding lead service line replacements.
