In response to the requirements of the Federal Water Quality Act of 1987, San Antonio City Ordinance No. 98635 established monthly stormwater fees and rate schedules to protect the health, safety, and welfare of the community.
The stormwater fee is billed by SAWS on behalf of the City of San Antonio's stormwater utility to support and manage the operation and maintenance of the stormwater infrastructure, as well as for engineering, design, and capital improvements.
San Antonio's stormwater utility works to solve drainage problems and improve surface water quality, to prevent future problems, and to repair, maintain, and enhance the storm water infrastructure.
On Sept. 10, 2015, the San Antonio City Council approved revisions to the Stormwater Fee structure using an impervious cover approach. The 2016 fees shown below reflecting the new approach were effective Jan. 1, 2016, and the 2017 fees shown below became effective on Oct. 1, 2016.
