California officials have approved the first-ever regulations that impose long-term limits on the amount of water the state’s municipal utilities can use annually.
The State Water Resources Control Board unanimously approved a major water-saving measure on Wednesday that is expected to save about 500,000 acre-feet of water annually by 2040.
According to the water authority, the savings will be enough to quench the thirst of more than 1.4 million homes for a year.
The regulations require the state’s largest suppliers to calculate separate water budgets based on residential indoor and outdoor water usage, as monitored by dedicated irrigation meters, and landscape consumption for commercial, industrial and public facilities.

“We have now formalized water conservation as a way of life,” said Joaquin Esquivel, chairman of the water commission.statement“The result is a balance between saving water and allowing our suppliers the flexibility they need to tailor their water-saving strategies to local needs and climate.”
The resulting budget, called the “urban water use target,” would be mandatory from 2027 and would become increasingly strict until 2040, according to the commission.
Water suppliers will be able to tailor their water conservation efforts to local needs through awareness campaigns, education, leak detection, discounts, and the installation of efficient equipment.
The regulation would apply to 405 municipal water suppliers, which serve approximately 95 percent of California’s population.analysisIt was created by the Water Bureau.
The analysis found that the resulting water-saving measures are expected to save the utility $6.2 billion from 2025 to 2050, at a cost of $4.7 billion. Over that same period, the water agency projects cumulative water savings of about 3.9 million acre-feet.
Some of the low-water consumers among 405 suppliers, such as the San Francisco Public Utilities Commission, do not have to change their current consumption practices to meet their individual budget goals.

The water savings from the newly approved regulations were significantly lower than those provided by the previous rules, sparking widespread backlash among suppliers.
Nonetheless, California officials touted the move as a much-needed strategic step to shore up the state’s water security.
“Achieving this milestone means more than adopting the first-ever conservation regulation to use a water budget,” said California Environmental Protection Secretary Yana Garcia.statement.
“This is a crucial step to ensure California’s long-term resilience to the hotter, drier weather we’re all experiencing,” Garcia added.
