Requires water purveyors to inspect and repair underground water distribution infrastructure; establishes certain liability of water purveyors.

This New Jersey bill mandates that water providers regularly inspect and repair underground pipes, valves, and fire hydrants to prevent leaks and infrastructure failures. It requires specific maintenance schedules, such as testing valves every four to eight years and inspecting underground lines every five years, with more frequent checks for older iron pipes or those in sinkhole-prone areas. The legislation also obligates companies to mark hydrants, map infrastructure locations using GPS, and keep detailed records of all maintenance for at least 12 years. Finally, the bill establishes penalties for water providers that fail to comply with these new inspection and repair requirements.
