Agua Vista Station is a water treatment plant in North San Antonio that will condition the potable water received via 142-mile pipeline from Burleson County and make it compatible with the five other water supplies that will potentially mix with Vista Ridge water in the SAWS water distribution system. The project was carried out by Ferrovial subsidiary PLW Waterworks, a joint venture between Ferrovial’s subsidiaries Webber and Cadagua.
Agua Vista Station is sized to condition the peak Vista Ridge flows of nearly 50 million gallons per day, which is almost 20 percent of the average daily water demand in San Antonio.
Project is 98 percent complete. Phase 2 of the construction was completed on April 19, 2020. Project team is currently working on landscaping and punch list items in order to finish out the project. There has been over 18,000 tons of structural backfill placed and over 60,000 tons of material hauled off. Over 6,300 cubic yards of concrete were placed as water bearing structures, slabs, and concrete roadways.
