SB 606 and AB 1668, signed in 2018 and referred to as the Long-Term Framework legislation, are intended to make conservation a California way of life. The legislation tasked the California Department of Water Resources (DWR) with providing regulation recommendations to the State Water Resources Control Board (State Water Board) that include water use efficiency standards and performance measures for urban retail water suppliers. Both are intended to improve water efficiency at an urban retail water supplier level. Standards establish quantitative requirements, such as annual water use relative to water budgets, that must be tracked and reported. Performance measures are more qualitative in nature and will require implementation of various conservation measures and programs, for example.
This cut sheet provides a general overview of the regulation as well as a “cheat sheet” of calculations for each standard included in the urban water use objective. This cut sheet is available to the general public.
