Title: City of Davis ASR Pilot Testing Project
Description: The City of Davis is preparing to conduct short-term aquifer storage and recovery (ASR) testing at two of the City of Davis’s inactive water supply wells. ASR is a water management technique that involves injecting and storing drinking water in an aquifer for later recovery and beneficial use. The City of Davis plans to test two inactive supply wells, Well 11 and Well 27, to gain information on site-specific injection rates and recovery rates, and groundwater level and groundwater quality responses to ASR. The ASR pilot testing will be conducted by injecting drinking water from the City of Davis’s water distribution system into the aquifer using Well 11 and Well 27 in three cycles of injection, storage, and recovery. The total duration of the testing is estimated to be for six months beginning in October 2025. The duration of the three cycles will be approximately 15, 30, and 75 days, respectively. Data collection activities will consist of monitoring injection and recovery flow rates, groundwater levels and groundwater quality in the two supply wells during ASR pilot testing. This information will be used to support development of a potential future ASR project for the City of Davis under a separate environmental review.
