Dos Rios Celebrates 30 Years of Innovation

A place you have a close relationship with, but may not know well is celebrating its 30th anniversary. The SAWS Dos Rios Water Recycling Center has been receiving and treating wastewater from most of San Antonio for three decades.

imageLocated on the city’s South Side, Dos Rios replaced the Rilling Road sewage treatment plant in 1987. At the time, it was the largest municipal construction project ever completed in San Antonio and created a significant boost in flows for the Medina, San Antonio and Guadalupe rivers.

Today, Dos Rios remains a cornerstone of the city’s sewage system and showcases SAWS’ leadership in water management innovation:

  • Largest direct recycled water system in the nation.
  • First in the world to produce treated biogas for the natural gas market.
  • First to accomplish the environmental “trifecta,” reusing all three sewage treatment by-products: water, biosolids and methane gas.
  • First in the world to produce renewable sources for water, methane and solar power from one plant.
  • Environmental Protection Agency's best treatment plant in the U.S. in 2004.

Even the water along San Antonio’s River Walk comes from Dos Rios, providing much of the famed river’s flow all the way down to the Texas coast.
