Grease Trap Maintenance for Hospital Kitchens

Hospital Kitchen Grease Trap Requirements & Regulations

Hospital kitchen grease traps must comply with local plumbing codes (typically based on the International Plumbing Code) and state environmental regulations. Most jurisdictions require grease interceptors with a minimum capacity based on peak flow rates—hospitals usually need 1,500+ gallon units due to high-volume cooking operations. The FDA Food Code and state health departments mandate that grease traps be pumped when they reach 25% capacity (some jurisdictions require 10% for hospitals) and inspected regularly by certified haulers. Documentation of all pumping, inspections, and repairs must be maintained for compliance audits by local health departments and state regulators.

Common Maintenance Mistakes & Compliance Pitfalls

Many hospital kitchens fail to establish documented maintenance schedules, leading to surprise violations during health inspections. Pouring hot grease directly into drains—even with strainers—bypasses the trap and causes FOG buildup in municipal sewer lines, triggering fines from wastewater authorities. Another critical mistake is ignoring pre-rinse sink stations and dishwashing areas, which contribute significant FOG loads that overflow traps. Hospitals often neglect to train dietary and housekeeping staff on proper grease disposal, resulting in incompatible waste entering the system. Failing to contract with licensed, certified grease haulers invalidates compliance documentation and exposes facilities to liability.

Best Practices to Maintain Compliance & Avoid Violations

Establish a written grease management plan aligned with your state health department's requirements and FDA Food Code guidance, with scheduled pumping before capacity thresholds are reached. Train all kitchen staff on proper FOG disposal: collecting grease in containers for rendering or disposal, not the drain. Implement strainers at all sink stations and ensure pre-rinse equipment discharges to the grease trap, not to floor drains. Contract with a licensed, certified grease recycling or disposal company and maintain dated receipts and capacity logs. Schedule quarterly inspections (more frequently during high-volume periods) and document all findings—this demonstrates due diligence if violations arise and helps your facility defend against citations from local health departments.
