Delaware River Basin Commission Invites Comments, Holds Nov. 4 Virtual Hearing On Proposed Regulation Requiring Water Supply Systems To Report Water Use By Their Larger Customers

The Delaware River Basin Commission invites comments on and scheduled a November 4 hearing on a proposed regulation change requiring water supply systems in the Delaware River Basin to report water use by their largest customers.

The virtual hearing will be held on November 4 starting at 1:30.  Click Here to register to provide comments.

The regulation change proposes to require water supply systems to report users of 50,000 gallons per day or more of water.

Approximately 300 water supply systems will be subject to this rule, but. Only a subset of these have customers that will meet the 50,000 bpd threshold.

From 1990 to 2020, water supply system water use declined in part due to a decline in large industrial customers, however, starting in 2021 water use in these systems has been increasing but the reasons for the increases is not known.

To ensure that uses of the Basin’s water resources remain sustainable, it is important that the Commission monitor and understand trends in water use, including by gaining a better understanding of how water delivered by public water supply systems is used.
