After 10 years of legislative and regulatory wrangling, New Jersey’s Board of Public Utilities (BPU) has reversed a long-standing ban on sub-metering in rental housing by permitting newly constructed, multifamily rental developments to implement potable water sub-metering, where end users pay for their own consumption rather than a fixed amount or percentage of the whole building’s usage.

The measure is expected to save billions of gallons of water per year. Sub-metering encourages people to conserve because they are fiscally responsible for paying the bill and held accountable for personal usage.
