Sewer Spill Challenges Continue

The residual impacts from tropical rains are causing flooding conditions in San Antonio resulting in more sewer spills.

Spills occurred at:

• 200 blk of Mayberry Avenue near NW 34th Street,
• 100 blk of Yolanda Drive near Bernice Drive,
• Chappie James Way Road at Lackland AFB,
• 12200 blk of Farview Lane in the Salado Creek area near Wurzbach Parkway

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.

All of the above sites have EPA Consent Decree projects associated with them. These and other 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.
