Cincinnati Grease Trap Compliance Checklist for Food Service

Cincinnati Grease Trap Size & Installation Requirements

The City of Cincinnati requires grease traps with a minimum 500-gallon capacity for most food service establishments, though larger operations may need 1,000+ gallons based on peak wastewater flow. All grease interceptors must be installed in accordance with the Ohio Building Code and Cincinnati Municipal Code Chapter 704, with accessible cleanout ports and baffles intact. The grease trap must be located between the kitchen sink drain and the municipal sewer connection, and plumbing must direct all FOG-producing equipment (fryers, griddles, dishwashers) through the interceptor. Installation requires City permits and inspection sign-off before operation.

Maintenance Schedule & Inspection Checklist

Cincinnati Health Department inspectors check grease trap liquid levels, baffles, and cleanliness during routine food service inspections (typically biannual for full-service restaurants). Operators must pump and clean grease traps when the depth of accumulated grease and solids reaches 25% of the trap's total depth—most facilities require pumping every 2–4 weeks depending on volume. Required maintenance items include: baffle condition (no cracks or deterioration), inlet and outlet pipes clear of blockages, trap lid properly sealed, and no visible FOG discharge into the sewer. Keep dated service records on file showing the licensed waste hauler's name, pumping date, and disposal method, as these are mandatory for compliance verification.

Common Violations & Prevention Strategies

The Cincinnati Health Department frequently cites violations for overflowing or improperly maintained grease traps, improper disposal of fryer oil directly into sinks, and missing or expired maintenance documentation. Failing to pump on schedule results in FOG buildup that blocks municipal sewers, triggering environmental violations and surcharge fees from the city. To avoid violations, establish a documented preventive maintenance contract with a licensed Cincinnati-area waste hauler, train staff on proper FOG disposal (never pour oil down drains), and conduct monthly visual inspections. Post your grease trap pumping schedule in the kitchen and retain all hauler receipts for at least three years to demonstrate regulatory compliance during Health Department inspections.
