Extensive Infrastructure

Odds are you'll never get a detailed look of San Antonio's water and wastewater infrastructure— a massive system of pipes, water wells, pumps, storage tanks, treatment facilities, and pump stations that is mostly below ground. But it's working hard for you every day to deliver water to your home or business while discreetly disposing of your used water.

  • SAWS maintains, inspects and cleans more than 12,000 miles of water and sewer pipes throughout the city — enough to stretch from South Texas to Australia!
  • A new 45-mile pipeline – dubbed the "integration pipeline" — adds water management flexibility to our massive underground storage site in southern Bexar County to simultaneously produce and to store/recover water. This allows us to direct our diverse water supplies where they’re needed most!
  • SAWS stands ready to provide water and new infrastructure to our military bases, further shielding them from potential base closures.
  • The Southwest Bexar Sewer Pipeline provides a backbone for wastewater service in the south and west areas of San Antonio, ultimately capable of providing service to more than 250,000 people in these fast-growing areas.
  • In a responsible settlement agreement with the EPA to reduce sewer overflows, SAWS will invest an additional $492 million in its sewer system over a 10-year period, ensuring a more reliable wastewater system for the future.
