Request for Proposals for Design Engineering for Beltz 9 Upgrades for Aquifer Storage and Recovery Project.

The City of Santa Cruz Water Department (City) intends to convert its existing production well, Beltz 9, to an aquifer storage and recovery (ASR) well. Pilot testing was conducted at Beltz 9 from November 2023 through June 2024 and after obtaining favorable results, the City decided to proceed with converting Beltz 9 to an ASR well.

The City is seeking proposals from qualified engineering firms interested in providing design engineering services required for this project. Services include developing construction plans, specifications, and bid documents for demolishing and/or retrofitting the existing discharge and facility piping, mechanical and electrical components and equipment, controls and SCADA integration, and associated appurtenances of the permanent ASR well facilities per City of Santa Cruz guidelines. The project will also utilize templates and guidelines that have been developed for the larger Santa Cruz Water Program. Engineering analysis will include best practices for converting an existing production well to an ASR well. The design of the Beltz 9 facility should take into consideration future growth of the City’s ASR program, joint operation with existing ASR wells (Beltz 8 and Beltz 12), and additional ASR wells that may be brought online in the future.
