San Diego, Calif., is one step closer to realizing its goal of using recycled water to provide a safe, reliable and cost-effective drinking water supply for the city. Officials recently selected MWH/Brown and Caldwell, an environmental engineering consulting and construction firm, to manage and assist in the delivery of the water supply.

The program, called Pure Water San Diego, is a 20 year plan to use to purify recycled water to make the city more environmentally friendly and resistant against drought, climate change and natural disaster, according to program materials.

“Pure Water San Diego is needed to secure a long-term, reliable water supply for the city,” San Diego Public Utilities Department director Halla Razak said in a statement. “We look forward to working closely with the team on the implementation of this very critical program.”

An initial 15-million gallon per day water purification facility is planned to be in operation by 2023, according to program materials. The long-term goal of the plant is to produce 83 million gallons, or a third of the city’s drinking water supply, per day. The city plans to achieve this goal by 2035.

Also included in the program are the construction of various water purification facilities, the continued operation of the city’s Advanced Water Purification facility, research on additional treatment barriers for a potential direct potable reuse program, regulation and legislative development and an education outreach program, according to the city. The program is budgeted at $2.7 million.
