Grant Funds Will Help Create Drought Resilience, Increase Investment In Recharge Projects, and Drive Regional Groundwater Sustainability
Today the California Department of Water Resources (DWR) awarded Westlands Water District, which serves as the Groundwater Sustainability Agency (GSA) for the Westside Subbasin, a $7.6 million grant as part of the Department’s Sustainable Groundwater Management (SGM) Proposition 68 Implementation Grant Program. This grant provides critical investment in the District’s efforts to ensure a sustainable groundwater basin.
“As we enter the third year of historic drought, Westlands remains committed to utilizing the most proactive, innovative, and scientifically-sound strategies in groundwater management,” said Tom Birmingham, general manager of Westlands. “This grant funding from DWR will be instrumental to the District’s implementation of the Sustainable Groundwater Management Act and to achieving groundwater sustainability. We are grateful for the support and investment in these vital projects.”
The grant funding will further three key efforts within the Subbasin: the Storage Treatment Aquifer Recharge (STAR) Program, Phase 1; the Westside Subbasin Groundwater Sustainability Plan (GSP) 5-year Update; and the Westside Subbasin Geophysical Investigation for Recharge Potential.
The STAR Program will establish a network of treatment and aquifer storage and recovery (ASR) facilities in the Westside Subbasin. These facilities will treat water from the unconfined upper aquifer and provide temporary storage of surplus supplies. Based on current design, each treatment facility could treat up to 10,000 acre-feet a year and each ASR well could inject up to 1,200 gallons per minute to be stored for later use. Phase 1 of the STAR Program includes planning and identification of locations for the treatment facilities.
The funding will also support the District’s 5-year review and update of the Westside Subbasin GSP. This update enables the District to assess the implementation of the GSP and incorporate the latest information on groundwater conditions, technology, and science. The 2025 update will reflect progress towards achieving the Westside Subbasin 2040 sustainability goals, key groundwater project, and SGMA regulations compliance.
Lastly, the grant provided by DWR will also provide funding for the Westside Subbasin Geophysical Investigation for Recharge Potential. This Investigation consists of conducting geotechnical examinations on lands within the Westside Subbasin to identify groundwater recharge potential. The data collected will help interested parties, such as growers and/or the District, determine if a proposed site is feasible for groundwater
