Flooding Triggers Sewer Spill on Swiss Oaks Drive

San Antonio Water System crews are responding to a sewer spill that occurred on the 6600 block of Swiss Oaks Drive. The spill is a result of recent rains inundating sewer lines in the area. (See attached TCEQ notice for more details.) No adverse impacts are expected since the spill has been heavily diluted by stormwater.

The SAWS W-6 Upper Segment and W-1 Lower Segment sewer projects, which include this area, are under construction for $167.7, and $19.0 million, respectively. W-6 will replace existing 54-inch sewer mains with approximately five miles of 104-inch sewer pipe. The W-1 project will replace 42- and 54-inch sewer main with approximately two and a half miles of 72- and 78-inch main. This will replace aging infrastructure that conveys more than 90 percent of the sewer shed’s total flow to the treatment plant.

This project is part of the work required by San Antonio’s agreement with the U.S. EPA to address capacity constrained sewer infrastructure across the city.
