Thunderstorms Trigger Sewer Overflow on Holbrook Road

San Antonio Water System crews are responding to a sewer spill that occurred as a result of heavy thunderstorms yesterday.

The spill, which occurred at several locations along Holbrook Road between Austin Highway and Rittiman Road, has exceeded the requirement for public notice at this location. Crews have begun cleanup of the area. See TCEQ notice for more details.

No adverse effects are expected since the spill was heavily diluted by storm water. SAWS will continue to monitor the area. .

Areas prone to sewer overflows are the focus of projects replacing and upgrading capacity of sewer lines. SAWS presently has two active projects along Holbrook to address these sewer spills with a total construction cost of $65 million. The initial phase of the project is over 80 percent complete and the second phase is 30 percent complete.
