Potable Supply and Sold/Exported for URWS

This table contains fields from potable supply and water sold/exported data reported by public water systems owned and operated by urban retail water suppliers. The list of public water systems in this resource is based on the PWSID-DWRID crosswalk resource that is also a part of the Urban Water Use Objectives dataset.

Consistent with Health and Safety Code section 116530, public water systems submit a technical report to the Board in a form and format and at intervals specified by the state; these data are submitted through the SAFER Clearinghouse. For each system, the table includes potable water use data, as well as volumes sold or exported to other entities, if provided by the supplier. All values have been converted to gallons by State Water Board staff.

If the values identified in this dataset need to be revised, a supplier may reopen an already submitted report in the SAFER Clearinghouse to revise and re-submit. For more instructions on how to revise a report, consult the Clearinghouse Reporting User Guide found here.
