SACRAMENTO, Calif. – Today, the Department of Water Resources (DWR) announced new steps that, if approved, could save enough water to supply 4.7 million Californians annually while making conservation more affordable through financial assistance and tax exemptions. The actions improve long-term water conservation and reduce wasteful outdoor water use as California adapts to a hotter, drier future driven by climate change.

“We have the tools to make it easier than ever for Californians to conserve water and we’re taking action to get it done. It will take forward-thinking practices to ensure that we’re managing our water resources resiliently now and for the future,” said DWR Director Karla Nemeth. “From regulatory recommendations to funding for lawn replacement and water conservation, DWR is putting California on the path to achieve historic water savings.”


The new actions will build on California’s ongoing long-term efforts to make water conservation a way of life while advancing water efficiency efforts outlined in California’s Water Supply Strategy: Adapting to a Hotter, Drier Future. The plan, released by Governor Newsom this summer, sets a target of securing 500,000 acre-feet of additional water per year through increased efficiency and conservation.

DWR will be implementing and supporting actions that include:


Outdoor Water Use Recommendations

To help prepare for a hotter and drier future, DWR has submitted outdoor water use efficiency recommendations to the State Water Resources Control Board. With outdoor water use accounting for 50 percent of urban resident water use on average, the recommendations outline standards that would provide urban retail water suppliers with a framework to support more efficient outdoor residential water use. The framework will also include standards for the irrigation of large commercial, industrial, and institutional (CII) landscapes in their service areas.

DWR’s outdoor water use recommendations combined with indoor residential water use recommendations submitted in November 2021 would result in expected long-term water savings of 450,000 acre-feet per year starting in 2030 – enough water to supply about 1.6 million homes or about 4.7 million residents for both indoor and outdoor annual needs. The recommendations would also result in near-term savings of 100,000 acre-feet a year starting in 2023. DWR’s recommendations will be evaluated by the State Water Resources Control Board through a formal rulemaking process, which will include additional analysis, engagement, and opportunity for public comment.

Indoor Water Use Legislation Signed

California also recently took additional steps to increase indoor water use savings with Governor Newsom’s signing of Senate Bill 1157 (Hertzberg), which adopts recommendations made by DWR and the State Water Board last year to reduce indoor water use targets to 47 gallons per day by 2025 and 42 gallons by 2030. By adjusting indoor water use standards to reflect the joint recommendation of DWR and the State Water Board, the legislation will help increase water conservation and water use efficiency, ensuring a more water-resilient future for California.

Financial Assistance for Turf Transition and Conservation

DWR has developed a set of funding programs that will help build resiliency in all communities including underrepresented communities and Tribes. The funding programs include financial assistance for projects that strengthen resilience in urban communities, turf transition for residential and commercial landscapes and water conservation programs for urban water suppliers. DWR’s programs will help to clear some of the hurdles that underserved communities face with direct install programs and support for local water agencies, while also helping build resiliency with equity in mind. DWR plans to release these grant programs in October. These new programs will build on the momentum created by the millions of dollars in grant funding that has been distributed by DWR in 2022.


Turf Tax Exemption

For those making smart water decisions to replace their lawns now and in the future, Governor Newsom signed Assembly Bill 2142 (Gabriel), which will exempt from state income tax calculations any grant, rebate or additional financial assistance awarded from a state or local agency for turf transition. The law will provide the exemption through tax year 2027.


These announced actions come on the heels of state and local leaders gathering today at the Bay View Google Campus to discuss the urgent need for all Californians, including businesses, to conserve water amid extreme drought. With California experiencing a climate transformation bringing hotter and drier conditions, each individual act of conservation makes a difference.
