Rains Result in Sewer Overflows

Recent rains have generated two sanitary sewer overflows. The spill amounts are estimated to have exceeded the need for public notice.

Spills occurred at 12000 block of West Avenue, and Chappie James Way Road at Lackland AFB. San Antonio Water System crews are monitoring the areas and will clean the area as floodwaters recede.

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.
