Rules Development for Water/Wastewater

The Public Utilities Commission (PUC) regulates privately-owned water and sewage treatment utilities in Hawaii. (The Commission does not regulate municipal water and wastewater utility services provided by local city and county governments.) As of mid-2016, the water and wastewater utilities regulated by the PUC included the companies listed in the following table. For a current list of all regulated utility providers, see the “Active Utility Companies Report” in the Document Management System.

Initial working drafts have been developed for each of the following:

Comments may be submitted via email to puc.rules@hawaii.gov, and will become part of the public record. Comments on draft #1 should be submitted by February 23, 2017.

Once we have reviewed the comments, we will revise the draft rules as appropriate. The final draft of the rules will be scheduled for formal hearing.
