Columbus Grease Trap Compliance Checklist for Food Service

Columbus Local Grease Trap Requirements

The City of Columbus requires all food service establishments to install and maintain grease traps or grease interceptors sized appropriately for their operation. Under Columbus Code Chapter 3713, grease traps must be located between the kitchen sink and the sanitary sewer system. Facilities must obtain approval from the Division of Health before installation. The trap's capacity must meet flow requirements based on your establishment's peak usage—typically 25% of the peak hourly flow for restaurants. Regular pumping schedules are mandatory; most Columbus establishments require pumping every 30 days or when the grease level reaches 25% of trap capacity.

Monthly Inspection and Maintenance Checklist

Establish a documented maintenance log tracking grease trap inspections, cleanings, and pumping dates. During monthly inspections, check that trap lids are secure and accessible, measure grease/solids buildup using a sight gauge or dip stick, and verify no grease or debris is accumulating in drain lines. Ensure the drain line from the kitchen to the trap is clear of clogs and blockages. Test that water flows freely through the system without backing up into sink drains. Document temperature—grease hardens in cold conditions and may require more frequent cleaning. Any visible cracks, corrosion, or damage to the trap structure must be reported to a licensed contractor for repair.

Common Columbus Health Code Violations to Avoid

The Columbus Division of Health frequently cites violations including failure to maintain grease traps, pumping records not available during inspections, grease overflow into municipal sewers, and use of additives or enzyme treatments instead of mechanical pumping. Improper installation of traps—such as undersized units or traps installed above ground level without proper venting—are critical deficiencies. Staff pouring grease directly down drains bypasses the trap entirely and triggers violations. Missing or damaged trap covers, which allow pest entry and create safety hazards, are documented violations. The Ohio EPA can impose environmental penalties for grease entering public waterways. Keep all pumping receipts and contractor communications for three years to demonstrate compliance during inspections.
