Wettest September on Record Triggers Sewer Spill

As San Antonio continues to experience the wettest September on record, the impacts from those rains continue to inundate the local sewer system.

San Antonio Water System crews are responding to a sewer overflow that occurred at the Falcon Center Lift Station on Boerne Stage Road by Interstate 10 West.

The spilled amount 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 Falcon Center Lift Station elimination project, which began in 2017, will be completed by the end of this year.

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.
