Report on the Evaluation of Water Audit Data for New Jersey Water Utilities

A report released on Jan. 17, 2017 by the estimates that statewide, New Jersey water utilities lose approximately 130 million gallons of clean drinking water per day through leaky pipes. Of that total, the report estimates that 50 million gallons per day could be recovered cost-effectively through investments in new or upgraded infrastructure.
According to the report, 50 million gallons is equivalent to the daily water use of a city more than twice the size of Newark, and represents approximately $10 million per year in potential recovered revenue.
To reach its findings, the NRDC analyzed what are known as water-loss audits from utilities under the jurisdiction of the Delaware River Basin Commission, which requires its water utilities to perform these audits and report the results. Water utilities in New Jersey that are outside the commissions’ jurisdiction are not subject to this requirement, so the NRDC extrapolated from the reported data to reach its statewide estimates.
