Real Water Loss Budget: System-Specific Standards

Consistent with California Code of Regulations title 23 §980 through §986, urban retail water suppliers are required to comply with real water loss standards. This table contains the real water loss standards for 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 and the April 9, 2024 water loss standards](https://www.waterboards.ca.gov/conservation/water_loss_control.html). Consistent with §984 of the California Code of Regulations, default parameters in the economic model used to generate system-specific standards may be updated, upon supplier request.
