San Antonio Food Service Water Testing Compliance Checklist

Local Water Quality Testing Requirements

San Antonio food service establishments must ensure water used for food preparation, cooking, and cleaning meets potability standards outlined in the Texas Food Rules and City of San Antonio Health Code Chapter 25. All facilities must use water from approved public water supplies or, if using private wells, provide annual bacteriological testing (total coliform and E. coli) conducted by a certified laboratory. Hot water systems must maintain temperatures of at least 120°F at all points of use, and cold water must remain below 70°F. Inspectors verify compliance by checking water temperature readings, reviewing test certificates, and inspecting treatment systems such as filters or UV disinfection units.

Common Inspection Violations to Prevent

Frequently cited violations include missing or expired water test certificates, inadequate hot water temperature maintenance, improper ice machine water supply connections, and failure to test private well water annually. The City of San Antonio Metropolitan Health District citations often target backflow prevention device failures, which allow contaminated water to flow backward into potable water supplies. Cross-connections—such as a hose running from a floor drain into a food prep sink—represent serious contamination risks. Ensure all equipment connections are reviewed during inspections, thermometers are calibrated and functional, and test results are retained for at least two years per regulatory standards.

Documentation and Inspection Readiness

Maintain a water compliance log that includes monthly hot and cold water temperature checks with dates and corrective actions. Store all water test certificates, backflow prevention device inspection reports, and equipment maintenance records in an accessible location during health inspections. San Antonio inspectors will request documentation of the water source, any treatment systems in use, and proof of regular monitoring. Develop a preventive maintenance schedule for water heaters, filters, and ice machines, and ensure staff training documents show that employees understand proper water handling procedures and temperature requirements.
