City advances aquifer storage planning; test borings and funding outreach next steps
Summary
Staff reported progress on aquifer storage and recovery planning, including desktop studies, grant outreach and plans to drill two test borings; staff cited preliminary design and drilling estimates (approximately $4.8M design and $5.8M drill per well) and said the next step is test drilling and geophysical characterizations.
City staff provided a quarterly update on aquifer storage and recovery (ASR) planning and early procurement steps.
Staff explained the ASR program seeks to diversify the city's water supply and storage beyond pre-1914 water rights and listed parallel projects (raw-water storage, Wickland cut, Tracy tie-in) being evaluated. Staff said the ASR program will complete desktop studies and then proceed to a test-boring program at two candidate sites (one near the water-quality basin north of Byron Highway and one near the southern tip of a developer parcel) with temporary access agreements under negotiation.
On costs, staff stated planning-level estimates of roughly $4.8 million for design and about $5.8 million to drill (per well) and said the city is considering two to three wells in total. The next immediate steps are issuing an RFP for test-boring contractors, completing the desktop study and performing the field test borings and geophysical logging to characterize aquifer cross-sections.
Staff also reported coordination with grant teams, lobbyists, and federal/state partners and described an early-stage funding pipeline and outreach; the city has spent a small percentage of the awarded project budget to date and expects test drilling to be the near-term capital activity.
