San Angelo sets reporting rules for data center coolant discharged into the city sewer
San Angelo adopted Ordinance 2026-076, which adds a data center subsection to the city's prohibited discharges rule. Any intentional release of treated cooling fluid into the sanitary sewer is defined as a discharge event, and sampling with laboratory verification has to be completed before each one. Records of volumes, results and dates must be kept for at least three years and handed to the Director of Water Utilities on request. Planned discharges need 72 hours written notice. Emergency discharges have to be reported within 4 hours with a written incident report inside 7 days. The council introduced the ordinance on May 19th, 2026 and adopted it on June 2nd, 2026.
How to take part
The ordinance is in force. Discharge records are held by the Director of Water Utilities and are producible on request. That makes them reachable through a Texas Public Information Act request to the City of San Angelo. The city publishes the adopted text on its data center page.
