The Global Water Awards shortlist write-up highlights that, “The H2Oaks Center is the only facility in the US that produces potable water from three different feedwater sources …the facility is fully automated with supervisory controls and data acquisition systems, and the entire process – from wellfield through to concentrate disposal wells – runs without a single break tank…one of the first major municipal water projects in Texas to utilise state legislation authorising alternative delivery methods” (Source: globalwaterawards.com).

The plant was successfully commissioned in 2017. It is located at the San Antonio Water System Twin Oaks Aquifer Storage and Recovery Site in a dedicated building called the ‘H2Oaks Center’. The building includes allocated space to house desalination equipment for subsequent phases.

Technical overview: The Phase I facility produces 45 MLD (12 MGD US) of finished water from 7.5 MLD (2 MGD US) of filtered well water blended with 37.8 MLD (10 MGD US) of RO permeate water. The plant achieves 90% recovery by the inclusion of four 8.4 MLD (2.22 MGD US) primary RO trains and two 2.1 MLD (0.56 MG US) secondary concentrator RO trains.

Raw water comes from a combination of wells between 1200 and 1800 feet deep and the quality is expected between 1300 and 1500 ppm total dissolved solids. Brine disposal is via ‘Class 1’ injection wells. Finished water quality meets all federal and local drinking water standards.
