Parsons awarded SAWS brackish-water desalination program
Parsons (Pasadena, Calif.; www.parsons.com) and a joint-venture (JV) partner, has been 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 6 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 gal/d reverse-osmosis (RO) membrane water-treatment plant, a 7.5-million gal/d 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,” says Virginia Grebbien, Parsons Group president.
