Wells 18, 19 & 20
Project Overview
The City of Vacaville Utilities Department is undertaking the Wells 18, 19, and 20 Project to bolster local groundwater resources. This initiative involves drilling three new production wells in strategic locations within the City. The wells are needed to ensure continued compliance with state regulations and a long-term, reliable water supply.
The new wells are expected to:
- Increase capacity, ensure redundancy, and support sustainable water management.
- Help maintain stable water levels supporting the overall health of our community.
- Have excellent water quality, meeting all state requirements (including hexavalent chromium six limits).
The project is divided into three sites: Well 18, Well 19, and Well 20. Each site will feature similar construction activities, with tailored considerations for local impacts.
24-Hour Operations
To minimize overall project duration, maintain safety and efficiency, and avoid repeated mobilization, certain critical activities will operate 24 hours a day, 7 days a week. Further, the drill will bore through subterranean clay formations that require 24-hour operations to prevent equipment from getting stuck if the clays swell. These include drilling, borehole reaming, and continuous test pumping to ensure the well meets performance standards before permanent installation. Nighttime operations will only occur when absolutely necessary.
Post Construction
Following completion of drilling operations, an aesthetically designed Concrete Masonry Unit building will house the well equipment. The structure will feature modern architectural elements and landscaping integration to blend seamlessly with the surrounding neighborhood and enhance visual appeal. No discernible noise is expected to be generated from the ongoing operation of the well pump.
