Water Conservation Emergency Regulations

As climate change-induced extreme weather disrupts California's water system, the State Water Resources Control Board at times adopts emergency regulations that encourage Californians to use water wisely and make conservation a way of life. Other than these statewide emergency regulations, some local water suppliers have adopted stricter water conservation measures than the State Water Board's, so water customers should check with local agencies about their current restrictions.

  Update

As of June 5, 2024, the State Water Board’s statewide water conservation emergency regulations have expired. All emergency regulations expire after one year from their effective dates, unless the State Water Board modifies, readopts, or ends them before then. Local authorities may adopt different and/or stricter water conservation measures; check with your supplier about current local restrictions. Please see below for more details, which are accurate as of June 5, 2024.

  • For urban water suppliers, statewide Level 2 demand reduction actions not required: The requirement for urban water suppliers to implement demand-reduction actions that correspond to at least Level 2 of their water shortage contingency plans has not been in effect since June 5, 2023.
  • For commercial, institutional, and HOA common areas, the decorative grass watering emergency ban has expired: The Emergency Regulation to Ban Decorative Grass Watering (non-functional turf irrigation) in commercial, industrial, and institutional areas, including HOA common areas expired by operation of law on June 5, 2024. In October 2023, however, the California State Legislature passed Assembly Bill 1572, which phases in a ban on decorative grass watering in commercial, industrial, and institutional areas permanently.
  • Emergency prohibition on wasteful water uses has expired: The Emergency Regulation to Prohibit Wasteful Water Uses (such as refilling fountains without recirculating pumps, overwatering landscapes, watering grass within 48 hours of rainfall, etc.) expired on December 21, 2023.

What are HOA requirements during drought emergencies?

According to the Davis-Stirling Act, a homeowners’ association (HOA) may not impose a fine for reducing watering of lawns or vegetation during a drought emergency that was either declared by the Governor or local government. Additionally, homeowners may remove their lawns and replace them with water-wise plants. If a homeowner installs water-efficient landscaping during the drought, an HOA cannot prevent them from maintaining it or require them to remove it when there is no longer a drought state of emergency. An HOA also cannot prohibit, or include conditions that have the effect of prohibiting, the use of low water-using plants as a group or as a replacement of existing grass. Please refer to the documents and links below for more information on HOAs and drought emergency resources:

On March 24, 2023, Governor Newsom's Executive Order retained a state of emergency for all 58 counties and maintained the ban on wasteful water uses, such as watering decorative grass on commercial properties.

January 2022 Emergency Regulation Documents

Following unprecedented water conservation and plentiful winter rain and snow, on April 7, Governor Edmund G. Brown Jr. ended the drought State of Emergency in most of California, while maintaining water reporting requirements and prohibitions on wasteful practices such as watering during or right after rainfall. Executive Order B‑40‑17 lifts the drought emergency in all California counties except Fresno, Kings, Tulare, and Tuolumne, where emergency drinking water projects will continue to help address diminished groundwater supplies. The Order also rescinds two emergency proclamations from January and April 2014 and four drought-related Executive Orders issued in 2014 and 2015. Executive Order B-40-17 builds on actions taken in Executive Order B‑37‑16, which remains in effect, to continue making water conservation a way of life in California. The State Water Resources Control Board maintains urban water use reporting requirements and prohibitions on wasteful practices such as watering during or after rainfall, hosing off sidewalks and irrigating ornamental turf on public street medians. As directed by Governor Edmund G. Brown Jr. in Executive Order B-37-16, the Board will separately take action to make reporting and wasteful water practices permanent.

State Water Board Partially Repeals Emergency Regulation on April 26, 2017

The Executive Director for the State Water Resources Control Board rescinds the water supply stress test requirements and remaining mandatory conservation standards for urban water suppliers. The action was in response to Governor Brown's announcement earlier this month ending the drought state of emergency and transitioning to a permanent framework for making water conservation a California way of life. Current prohibitions against wasteful water use practices and requirements for monthly water use reporting remain in place.

Supporting Documents Process

Making Water Conservation a California Way of Life, Implementing Executive Order B-37-16 On Wednesday, November 30, 2016, State Agencies released to the public a draft report for Making Water Conservation A California Way of Life. The Draft Report addresses elements of Executive Order B-37-16, which asked five state agencies to develop a framework for using water more wisely, eliminating water waste, strengthening local drought resilience, and improving agricultural water use efficiency and drought planning. The public agencies, including the Department of Water Resources, State Water Board, California Energy Commission, Public Utilities Commission, and Department of Food and Agriculture, will accept comments on the report through December 19, 2016 (please send all comments to: wue@water.ca.gov).
