Philadelphia Grease Trap Requirements & Maintenance Guide

Philadelphia Grease Trap Regulations & Code Requirements

Philadelphia's health code requires all food service establishments to install and maintain grease interceptors (commonly called grease traps) sized appropriately for their operation. The Philadelphia Department of Public Health enforces these requirements under Chapter 13 of the Philadelphia Health Code, which aligns with the International Plumbing Code. Facilities must obtain permits for grease trap installation and submit sizing calculations based on kitchen fixture units, peak flow rates, and food preparation volume. Regular inspections verify that traps are operational, properly installed, and connected to municipal sewer lines rather than storm drains. Non-compliance can result in fines, operating restrictions, or closure orders.

Maintenance Schedules & Pumping Requirements

Philadelphia does not specify a one-size-fits-all pumping frequency in the health code; instead, maintenance must be based on grease trap capacity and volume of use. Most commercial kitchens require pumping every 2–4 weeks, though high-volume operations may need weekly service. Licensed waste haulers must pump traps and dispose of grease at approved facilities; restaurants must maintain documentation of all service dates, hauler certifications, and volumes removed. The Philadelphia Streets Department and Department of Public Health coordinate to ensure grease doesn't enter the city's aging sewer infrastructure, which is vulnerable to Fats, Oils, and Grease (FOG) blockages. Restaurants should establish a relationship with a certified hauler and track maintenance on facility records available for inspection.

Inspection & Enforcement by Philadelphia Health Department

Philadelphia's Department of Public Health conducts routine and complaint-driven inspections of food service facilities, including grease trap assessments. Inspectors verify trap accessibility, cleanliness, proper labeling, and lack of overflow or backup signs. Violations are cited under the Philadelphia Health Code and may require immediate corrective action or schedule a follow-up inspection. The city also coordinates with the Philadelphia Water Department on FOG-related sewage backups; restaurants contributing to blockages face enforcement from multiple city agencies. Staying current with maintenance records, engaging certified service providers, and promptly addressing violations is critical to maintaining your license and avoiding penalties.
