San Antonio Restaurant Grease Trap Requirements & Compliance Guide

San Antonio Local Grease Trap Regulations

The City of San Antonio requires all food service establishments to install and maintain grease traps or grease interceptors to prevent fats, oils, and grease (FOG) from entering the municipal sewer system. The San Antonio Department of Environmental Services enforces these requirements under the City's Grease Control Ordinance. Restaurants must obtain a Grease Control Permit and have their grease traps inspected during the initial health permit application. Trap size must be calculated based on the establishment's menu, peak meal hours, and wastewater volume. The city mandates that grease interceptors be pumped and cleaned regularly—typically every 30 to 90 days depending on usage—and all maintenance must be documented by a licensed waste hauler.

Texas State & Federal Standards vs. San Antonio Requirements

Texas state regulations under TCEQ align with federal plumbing and environmental standards but allow municipalities like San Antonio to enforce more stringent local codes. The International Plumbing Code (IPC) and Texas Plumbing Code set baseline interceptor sizing and installation standards; San Antonio often exceeds these minimums. Federal EPA guidelines address wastewater treatment and FOG management in municipal systems, but enforcement typically falls to local authorities. San Antonio's local requirements are often stricter than state minimums—for example, the city may require more frequent pumping intervals and more detailed maintenance records than surrounding Texas jurisdictions. Restaurants operating in San Antonio must meet the highest applicable standard: if local code exceeds state or federal requirements, the local standard applies.

Maintenance Documentation & Compliance Best Practices

San Antonio requires restaurants to maintain detailed maintenance logs showing pumping dates, waste hauler information, and trap capacity. These records must be available for inspection by the San Antonio Health Department and kept on-site for a minimum of three years. Restaurants should schedule preventive pumping before capacity limits are reached and use only City-approved waste disposal contractors. Regular staff training on proper FOG disposal—such as not pouring grease down drains—reduces trap overflow risk and extends maintenance intervals. Failure to maintain compliance records or exceeding pumping intervals can result in health department violations, fines ranging from $100 to several thousand dollars, and potential permit suspension or revocation.
