California has experienced many periods of drought and weather extremes, which due to climate change, are occurring more frequently. Governor Newsom expanded his Drought Proclamation statewide on Oct. 19, 2021 and encouraged the State Water Board to prohibit certain wasteful water uses. In addition, Newsom’s July 2021 Executive Order asks Californians to voluntarily reduce their water use by 15% from their 2020 levels.

Water and wastewater agencies continue to utilize lessons learned from the 2012-’16 drought. ACWA member agencies continue to support local investments in water supply resilience and continue to make water efficiency a California way of life so the state is always prepared for these climactic extremes.

Member Agency Drought Response Stories

Water Use Efficiency

In 2018, the California Legislature enacted two key policy bills—Senate Bill 606 and Assembly Bill 1668—to implement a new framework for long-term water conservation and drought planning for water suppliers. The two bills provide new and expanded authorities and requirements that affect water conservation and drought planning for water supplies, agricultural water suppliers, and small water suppliers and rural communities.

The Department of Water Resources (DWR), the State Water Resources Control Board (SWRCB), and other state agencies are currently implementing the legislation and developing data, information, guidelines and other technical assistance to help realize the bill’s intended outcomes. ACWA continues to engage on this issue through the Water Use Efficiency Work Group. Members interested in participating can contact ACWA Regulatory Relations Manager Chelsea Haines.

More information is available on ACWA’s Water Use Efficiency Page.


ACWA’s Drought Toolkit is available to assist ACWA member agencies with drought messaging as they engage with customers, stakeholders and the media. The toolkit includes urban and agriculture-related talking points and a climate resiliency handout.

The statewide Save Our Water campaign, in partnership with ACWA, has created customizable communications tools for ACWA member agencies to help their customers reduce water usage inside and outside the home throughout the winter and during the holidays. These materials are available to ACWA members online.

The Save Our Water Partner Toolkit is also available for the public and includes videos, radio ads, signage and social media graphics that can be used by agencies and municipalities.


Below are a number of resources available to help ACWA member agencies stay informed about the current drought situation.
