Deluge triggering sewer spills

 SAN ANTONIO –Tropical rains are causing flooding conditions in San Antonio which has resulted in sewer spills.

The spills occurred on Boerne Stage Road by Interstate 10 West, Swiss Oaks near Pinn Road and Leon Creek, and 1800 block of Austin Highway near Ira Lee Road. SAWS crews will initiate cleanup of the sewer spill areas once floodwaters recede.

The spilled amounts exceeded the requirement for public notice. See TCEQ notice for more details. No adverse impacts are expected since the spill has been heavily diluted by stormwater.

Areas prone to sewer overflows are the focus of projects replacing and upgrading capacity of sewer lines. Overall, SAWS has more than $170 million in capital improvements budgeted in 2018 to replace and upgrade sewer lines throughout San Antonio.

San Antonio Water System provides water and sewer services to more than 1.8 million customers, via more than 12,000 miles of pipe. A consent decree with the EPA requires San Antonio to reduce sewer spills. Please help us improve the sewer system performance by disposing of wipes in the trash, and by immediately reporting sewer spills or missing manhole covers at 210-704-SAWS (7297). 

See TCEQ Notice (pdf) for more details.
