California Adopts Landmark Water Conservation Regulation

California has introduced a significant new water regulation framework, “Making Conservation a California Way of Life,” aimed at enhancing water use and conservation. Approved unanimously by the State Water Resources Control Board, this framework impacts around 400 urban water suppliers, requiring them to adopt water-use budgets and meet local conservation goals. The regulation is a response to climate change-induced drier and hotter conditions and replaces the previous one-size-fits-all approach with more localized measures considering climate, population, and prior conservation investments.
The new rules, stemming from 2018 legislative bills, have faced extensive revisions due to feedback from local water groups and environmental organizations. These modifications include extended compliance timelines to 2040 and adjustments to conservation targets, addressing concerns about cost implications for smaller and disadvantaged suppliers.
While some stakeholders believe the rules do not go far enough in addressing future water shortages, others emphasize the need for immediate implementation. The framework also includes provisions for updating residential landscapes to reduce water loss and ensuring affordability and equity in compliance. The regulation will be enforced starting January 1, 2025, with a focus on progress and compliance rather than punitive measures.
