Requires water purveyors to conduct, and report to DEP, water loss audits.

This bill requires public water systems (those serving 15+ connections or 25+ people daily) to conduct annual water loss audits and submit validated reports to the New Jersey Department of Environmental Protection (DEP). Water purveyors must use the American Water Works Association's standards to measure water loss - defined as unaccounted water from leaks, breaks, meter errors, or unauthorized use - and assign a data validity score. The audits must undergo "level one validation," where an independent expert reviews the data. This directly affects water utilities statewide, mandating transparency in water loss tracking to improve system efficiency and conservation.
