The Nation’s Largest Direct Recycled Water System

In 1996, SAWS committed to building one of the nation’s largest direct recycled water systems. With over 20 years of operations, the recycled water produced from the SAWS Water Recycling Centers has proven important to SAWS’ diversification and conservation efforts.

AT&T Center Recycled Water Retrofit
Partnering with business is key to planning for the future, reducing water use and ensuring water quality. Companies that use recycled water – like Spurs Sports & Entertainment, which teamed up with SAWS in 2008 to add water-saving features at the AT&T Center – save 1.1 billion gallons of Edwards water each year.

Today, more than 130 miles of pipeline delivers highly treated recycled water to over 80 customers. This includes: industrial and commercial users, golf courses, municipal parks, universities, military, healthcare etc. The recycled water system can provide up to 25,000 acre-feet per year, thereby conserving large amounts of potable water. Currently, 12,000 acre-feet per year has been contracted, with more customers pending connection to the system every year to take advantage of recycled water benefits:

  • Cost effective for customers – lower cost alternative for irrigation and cooling purposes.
  • Environmentally responsible – using recycled water reduces demand on our potable water supply.

The recycled water system was also designed to supplement base flows in the San Antonio River and Salado Creek. Annually, about 5,800 acre-feet per year is used to ensure flow during low flow periods or in the event of a drought. The result has been significant and lasting environmental improvements for the aquatic ecosystems in these streams.

In addition to supplying base flow to the San Antonio River and serving our recycled water customers, SAWS also supplied CPS Energy over 33,300 acre-feet of recycled water for use in their electrical generation in 2020. Combined, this accounted for over 48,500 acre-feet of recycled water distributed, about 16 percent of SAWS’ total water demand (potable and non-potable) in 2020.

Water Recycling

In San Antonio we have learned to turn wastewater into valuable resources. We call it our environmental “trifecta” of recycled water, organic biosolids and methane gas.
