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 or their agents to enter properties to perform lead service line replacements, provided they give at least seven days' notice to property owners and residents, except in emergencies. The notice must include details such as the scheduled date and time of the replacement, potential water service disruptions, locations for supplementary drinking water, and remedies if access to the property is not granted. Additionally, after the replacement is completed, municipalities are required to send a certified letter to the property owner summarizing the work performed.

The bill also defines key terms, including "municipal water system" and "service line," to clarify the scope of the legislation. Importantly, the provisions of this Act will only take effect if the Louisiana Constitution is amended to permit the use of public funds for identifying, inventorying, removing, or replacing drinking water service lines that are hazardous, including those made of lead, copper, or galvanized materials.
