Detroit Grease Trap Requirements for Restaurants
Detroit restaurants must comply with strict grease trap and grease interceptor regulations enforced by the Michigan Department of Health and Human Services (MDHHS) and Detroit Health Department. Improper grease trap maintenance can result in violations, fines, and sewage backups that threaten food safety. This guide covers Detroit's specific requirements, inspection protocols, and best practices for staying compliant.
Detroit's Grease Trap Regulations & Local Requirements
The Detroit Health Department requires all food service establishments to install and maintain grease traps or interceptors sized according to the Michigan Plumbing Code and Detroit's adopted building codes. Facilities must have traps inspected and cleaned on a schedule determined by the health department—typically every 30 to 90 days depending on usage volume and trap size. Documentation of maintenance must be kept on-site and available during inspections. Failure to maintain proper grease trap records can result in violations and citations from the Detroit Health Department.
How Detroit Health Department Inspections Work
Detroit Health Department inspectors evaluate grease trap functionality, sizing, and maintenance documentation during routine food facility inspections. Inspectors check for visible grease accumulation, proper venting, and compliance with the Michigan Plumbing Code. Facilities must maintain grease levels below the trap's design capacity; overfilled traps are cited as imminent health hazards. The department also verifies that facilities have contracts with licensed grease disposal services and maintain pumping records with dates and amounts removed.
Best Practices for Detroit Grease Trap Compliance
Establish a regular cleaning schedule with a licensed Michigan-certified grease hauler and keep all receipts and documentation on file. Train kitchen staff to pre-scrape dishes and minimize grease disposal down drains—this reduces trap cleaning frequency and extends equipment life. Install grease interceptor alerts or monitoring systems to track grease levels in real time and prevent overfilling. Schedule professional inspections quarterly and address any blockages or drainage issues immediately to avoid violations and costly sewer backups that disrupt operations.
