Beltz 8 Upgrades for Aquifer Storage and Recovery Project

Bids will be received for a single prime contract for converting an existing drinking water production well at Beltz 8 into an aquifer storage and recovery (ASR) facility. The Engineer’s estimate anticipates that the total base bid price will be $3.6 million and the Contract Time for the completion of all the Work of the Project included in the base bid is 370 days. The Engineer’s estimate anticipates that the total base bid price plus additive bid items will be $3.8 million; the Contract Time for the completion of all the Work of the Project, including additive bid items, is 390 days. The proposed Work is generally described as follows:

1. Demolition and modification of the existing production well facility
2. Modification of existing mechanical, piping, electrical, instrumentation, and control systems
3. Installation of new yard piping (raw water, potable water, storm drain), electrical conduits, and
instrumentation
4. Installation of downhole control valves and new column piping
5. Ancillary improvements in support of the foregoing

The Water Department has been implementing the supply augmentation recommendations of the Water Supply Advisory Committee (WSAC) since early 2016 and more recently the ongoing evaluation, selection, and construction of supplemental water supplies as directed by the Securing Our Water Future Policy. The recommended strategy is developed around the goal of delivering long-term water supply security to the City of Santa Cruz water customers. While Water Department staff are studying and testing the feasibility of the planned recommendations that include in-lieu water transfers and exchanges, aquifer storage and recovery (ASR), recycled water, and desalination, ASR has been advanced to the point at which permanent facilities are ready to be designed and constructed at several locations. This project will convert the Beltz 8 production well into an aquifer storage and recovery facility.
