Pilot testing was conducted at Beltz 12 in 2019 and at Beltz 8 in 2020-2021; further study of the operational characteristics of the wells as ASR facilities began in January 2022 and is anticipated to continue through Summer 2023. Ancillary studies are underway or planned to evaluate the suitability of other City-owned production wells for conversion to ASR wells. The City is seeking proposals from qualified engineering firms interested in providing design engineering and bidding assistance services required for this project.

Engineering analysis will include determination of recharge flow-control mechanism, ASR well hydraulics, and best practices for converting an existing production well to and ASR well. The design of Beltz 8 and 12 facilities should take into consideration future growth of the City’s ASR program and additional ASR wells being brought online.
