Equestrian Tank Rehabilitation Project Design

The contract pertains to the rehabilitation design project for the Equestrian Tank, a 4.2 million gallon potable water storage reservoir located in Westlake Village, California. Constructed in 1971 as a below-grade concrete tank within the 1227-foot pressure zone, the facility serves the local community by providing potable water. Since 2004, the tank has exhibited alkali-silica cracking (ASC) in its structural elements, with ongoing inspections noting these cracks primarily in columns and pilasters, though no major structural distress has been identified. As part of the District’s ongoing maintenance program, which includes yearly inspections and cleaning of selected potable and recycled water tanks, this rehabilitation project aims to extend the tank’s service life by addressing these structural issues and any additional concerns uncovered through detailed consultant investigations. The project scope will include necessary repairs to key structural components such as footings, columns, pilasters, and the roof, potentially utilizing methods like crack injection or CFRP wrapping. Additionally, the rehabilitation will incorporate updates to site security measures, which may involve conduit installations for future security cameras, electronic lock upgrades (to be installed by others), improved fencing, and enhanced lighting. Seismic retrofitting may also be required if deemed necessary by the consultant’s assessment. The solicitation for this project was issued by the California Engineering & Facilities agency under solicitation number 2026-RFP-041, with a response deadline of March 19, 2026. The project adheres to applicable procurement guidelines, including those supporting Disadvantaged Business Enterprise (DBE) participation as outlined by California State Revolving Fund program requirements, ensuring compliance with fair share objectives and contracting regulations. The primary contact for this solicitation is John Soderberg, Assistant Engineer.
