Rain triggers sewer spill

San Antonio Water System is responding to a sewer spill that occurred as a result of recent rains. The spill occurred on the 6600 block of Swiss Oaks Road near Pinn Road and Leon Creek, exceeding the requirement for public notice.

SAWS crews will initiate cleanup as stormwaters recede. No adverse impacts are expected since the spill has been heavily diluted by stormwater.

See TCEQ notice for more details.

SAWS Board of Trustees approved $2.6 million earlier this month for an emergency project to minimize spills near Swiss Oaks. This work should be completed in January. SAWS is pursuing a long-term solution to the problem which will require over $200 million in capital improvements.

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.
