Relentless Storms Lead to Sewer Spills

The impacts from recent rains are causing flooding conditions in San Antonio, resulting in two sewer spills. The spills occurred on the 6600 block of Swiss Oaks Drive and on W. Military Drive near W. Commerce.

SAWS crews will initiate cleanup of the sewer spill areas once floodwaters recede.

Each of 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.

The two sites have EPA Consent Decree projects that aim to prevent future spills. These and other areas prone to sewer overflows are the focus of projects to replace and upgrade the 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.
