San Diego Food Service Water Testing Compliance Checklist

San Diego-Specific Water Testing Requirements

All food service facilities in San Diego County must maintain adequate water supply and quality under DEHQ jurisdiction. Your establishment requires testing for bacteriological contamination (total coliform and E. coli), chemical contaminants per California's Primary Drinking Water Standards, and turbidity measurements. San Diego's Public Utilities Department provides municipal water testing, but food service operators are responsible for verifying compliance, including private wells or alternative water sources. Testing must be conducted by a certified laboratory approved by the California Department of Water Resources. Documentation of all water test results must be retained on-site for a minimum of 12 months and made available during inspections.

Critical Inspection Points & Testing Items

DEHQ inspectors evaluate your water system for cross-contamination risks, backflow prevention devices, and proper plumbing installation. Your facility must have NSF-certified or WaterMark-certified backflow prevention assemblies tested annually by a certified technician—this is a frequent violation point. Inspect water storage tanks for signs of corrosion, sediment, or contamination; they must be covered and accessible for cleaning. Check that hot water reaches at least 120°F at the tap and cold water stays below 70°F. Verify that hose bibs have vacuum breakers installed, that ice machines draw from potable water only, and that handwashing stations have continuous hot and cold water. pH levels should remain between 6.5 and 8.5 per California standards.

Common San Diego Water Testing Violations to Avoid

Missing or expired backflow prevention device certifications top the violation list in San Diego—ensure your annual testing is completed by June 30 each year. High total coliform counts trigger immediate corrective action requirements and potential closure; this often stems from cross-connections or contaminated storage tanks. Operators frequently fail to document water testing results or maintain records beyond the required timeframe. Improper water temperature maintenance, especially in dishwashing and handwashing stations, is cited regularly. Absent or defective vacuum breakers on hose connections create cross-contamination pathways. Failing to disclose private well or alternative water sources during initial permits or inspections can result in substantial fines and operational suspension.
