Sustaining Groundwater Resources

Protecting the health of California’s groundwater basins into the future.

Sustainable Groundwater

Groundwater is one of California’s most precious water resources. In many cases the demand for groundwater is directly related to the reliability and availability of surface water supplies so in dry years groundwater use can increase drastically resulting in severe overdraft.


ACWA's Efforts

Bringing the state’s critically over-drafted groundwater basins back into balance is vital to California’s water future. In 2019 ACWA prepared “A Technical Framework for Increasing Groundwater Replenishment” in response to a growing need to promote groundwater replenishment activities as a strategy to maintain or improve groundwater levels statewide.



The passage of the Sustainable Groundwater Management Act (SGMA) in 2014 was the first time in California water history that a statewide regulatory framework for groundwater management was enacted with outcome-based metrics and local control at its foundation.

ACWA Member Efforts

ACWA members throughout the state are forming Groundwater Sustainability Agencies, developing governance plans, conducting stakeholder outreach, researching current conditions, and drafting plans to bring overdrafted groundwater basins back into balance.
