>“We need to have a culture of efficiency in our state,” Walker said. There are plenty of ideas for conservation and reuse of water in the State Water Plan that need funding, she said, especially in smaller rural communities that don’t have as much technical expertise as larger cities and their utilities. “There’s a lot of good things we can be spending money on.”
>
>While both the proposed legislation and the current state water plan acknowledge that Texas also needs to conserve water and fix existing water systems, so far leaders seem more focused on grander plans to build new infrastructure.
Until Texas bans lawn watering state-wide, we ain't fuckin' serious about the water crisis.
>These days, SAWS [San Antonio Water System]—which serves 2 million people in Bexar, Medina, and Atascosa counties—has nine different sources of water. The utility can now draw from four additional underground aquifers, its own recycled wastewater, and three reservoirs, including Medina Lake. But because of drought, San Antonio hasn’t used Medina Lake for years.
>
>SAWS has invested instead in its “advanced storage and recovery” system as a better insurance policy. The utility doesn’t always use its full annual water rights from the Edwards Aquifer, especially during rainy times. So SAWS has turned to injecting extra Edwards water into a different rock formation directly below the H2Oaks Center, the Carrizo Aquifer, to use later during dry summers and droughts. Utility staff refer fondly to this reserve as “the bubble.”
>
>All this water used in homes, businesses, and public buildings throughout San Antonio eventually flows from drains and toilets downhill to the city’s lowest elevation point, where SAWS has built its wastewater recycling plant. Here, trash—mostly “flushable” wipes that in reality are not at all flushable—gets screened out of the water, and the plant’s workers diligently cultivate microbes that eat the city’s biological waste.
>
>At the end of this lengthy process, the treated water flows into the Medina River, just above where the Medina itself flows into the larger San Antonio River. The water entering the river looks clean, like a small waterfall more than anything. Trees surround the wastewater plant’s outfall, the air smells fresh, and birds fly by.
>
>“You should take us for granted,” said SAWS CEO Robert Puente, who previously served in the Texas Legislature and chaired the House Natural Resources Committee, in an interview with the Observer. The utility has plenty of water for at least the next decade, and longer if San Antonio’s recent population growth levels out, he said.
Excellent! So we already have a model for what every other city needs to be doing.
