Water Conservation Regulations in Effect

In 2022 California recorded its driest January through March on record, entering a third consecutive year of drought. On March 18, 2022, the Department of Water Resources, operator of the State Water Project (SWP), announced that water agencies throughout California should prepare for an allocation of only 5 percent of a full supply for 2022. Without a local water source, the City of Thousand Oaks depends almost entirely on imported water from the SWP purchased through Calleguas. With the significantly reduced SWP allocation, there are insufficient supplies to meet current demands for water in SWP-dependent service areas.

As a result of the drought emergency, which is affecting not only SWP-dependent communities but all Californians, on March 28, 2022, Governor Newsom issued Executive Order N-7-22 requiring each urban water supplier to undertake Stage 2 measures to reduce water usage by at least 20% and encouraging them to activate Stage 3 measures to reduce use by 30 percent. The order also directs the Department of Water Resources to develop emergency regulations defining and banning non-functional turf (ornamental grass) irrigation in commercial, institutional, and industrial sectors.  

Metropolitan Water District (MWD), which contracts for water from the SWP for Southern California, is currently evaluating the best way to quickly achieve substantial cuts in water usage so there is sufficient water available through the end of this year. On April 26, the MWD Board declared an Emergency Water Shortage and directed all State Water Project users to cut back to one-day-per-week irrigation. MWD, the largest contractor on the SWP, warned that the failure of customers to meet required conservation levels would result in a shortfall of water in the SWP distribution system and that as early as September all outdoor irrigation could be prohibited.

On May 24, 2022 City Council declared a Level 4 shortage, which reduces watering to one day a week consistent with the announcements by Metropolitan and Calleguas Water Districts, our suppliers. You can read the staff report here and watch the meeting here.
