PASADENA, CALIF. — Parsons and a joint venture (JV) partner were selected by the San Antonio Water System (SAWS) to serve as the construction manager at-risk (CMAR) for its critical brackish groundwater desalination program. This $86 million CMAR contract includes preconstruction phase collaboration with the SAWS program management and design teams, construction of all program components, and six months of treatment plant operations.

The scope of work includes 13 raw water production wells, raw and finished water conveyance, residual conveyance, three deep injection wells, a 10 million-gallon-per-day (mgd) reverse osmosis membrane water treatment plant, a 7.5-mgd finished water storage reservoir, chemical treatment systems, supervisory and data acquisition controls, and a new administration building that incorporates a public tour route, pilot plant, and training facility.

“Parsons is pleased to be collaborating on this important project that advances SAWS’ sustainable water supply strategy by preserving potable groundwater aquifers and employing reverse osmosis membrane technology to desalinate previously untapped brackish groundwater,” said Virginia Grebbien, Parsons Group president
