WDBC member Parsons recently held a groundbreaking ceremony to kick off construction of a brackish groundwater desalination project for the San Antonio (Texas) Water System (SAWS). Event participants included SAWS trustees and San Antonio Mayor Julián Castro as well as other state and local dignitaries.
In 2013, Parsons—along with a joint venture partner—was selected by SAWS to serve as the construction manager at-risk for this critical program. The scope of work includes 13 raw water production wells, raw and finished water conveyance, residual conveyance, three deep injection wells, a 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 the first phase of the desalination plant and public access facilities.
“As a member of the joint venture team providing construction management at-risk services for San Antonio Water System’s brackish groundwater desalination program, Parsons is honored to have participated in last week’s ceremony, which marked an important step forward for the project,” said Garry Higdem, Parsons Group President.
“We look forward to assisting our customer in their efforts to both advance their sustainable water supply strategy and meet the community’s future water needs,” added Virginia Grebbien, Parsons Group President.
“It is becoming more and more common for cities to look at brackish water. El Paso is already doing it, (and there are) several cities that are looking at it,” said SAWS Director of Engineering Ashok Kaji. “This is the technology that is relatively simple to do and certainly it is going to grow exponentially in the future because of the scarcity of water.”
Construction has begun and completion of the first phase is slated for 2016—with two additional phases to follow. When completed, SAWS’ plant will be the largest inland desalination plant in the United States.
