Regulation Rulemaking on Urban Water Supplier Monthly Water Conservation Report

The State Water Board adopted a drought emergency water conservation regulation in July 2014. The regulation required the state’s larger urban water suppliers (those with more than 3,000 connections or supplying more than 3,000 acre-feet of water annually) to provide the Board monthly water conservation and production reports. The Board required the monthly reports until the emergency regulation expired in November 2017; since then, most urban suppliers reported voluntarily. In May 2018, Governor Brown signed into law water efficiency legislation (Senate Bill 606 and Assembly Bill 1668). This legislation created water use efficiency standards and authorized the State Water Board to require monthly water production, water use, or water conservation reports on a non-emergency basis.

The reports include information on residential water use, total potable water production, measures implemented to conserve water and improve efficiency, and local enforcement actions.  The proposed regulation would require monthly reporting of key elements and additional information during water shortages. The regulation on Monthly Urban Water Conservation Reporting was adopted by the State Water Board at its regularly scheduled April 21, 2020 Board Meeting. It was subsequently approved by the Office of Administrative Law (OAL). The regulation will become effective on October 1, 2020.
