Commercial Grease Trap & Interceptor Service in Minnesota

Minnesota restaurants and food service operations typically need grease trap cleaning every 30–90 days depending on cooking volume, trap size, and menu (high-fat cooking loads traps faster). Most municipalities follow the "25% rule" — clean the trap before the combined grease and solids layer reaches 25% of the trap's liquid capacity. High-volume kitchens (over 200 covers per day) often require monthly service to stay compliant.

Overflow grease enters the sanitary sewer system, where it cools, hardens, and bonds with other debris to form fatbergs — massive blockages that can cost thousands to clear from municipal lines. This triggers regulatory violations, potential fines, and in serious cases, temporary closure orders. It also creates sewage backup risk into your kitchen, which is both a health hazard and an insurance event. Regular cleaning is always cheaper than emergency response.

Under-sink grease trap cleaning in Minnesota typically runs $100–$300 per service. Large exterior grease interceptors (500+ gallon buried units) run $300–$800 per pump-out depending on volume and disposal requirements. We offer monthly and quarterly service contracts at reduced per-visit rates — which makes sense for any operation that needs regular service.

A grease trap is a small unit (typically 10–100 gallons) installed under a sink or in a floor drain assembly. It captures grease from a single fixture. A grease interceptor is a large underground tank (500–2,000+ gallons) that handles the total wastewater flow from an entire commercial kitchen. Both need regular cleaning — interceptors just hold more between services and are typically required for medium-to-large commercial operations.

Yes. We provide a written waste manifest for every service call documenting the date, grease and solids volume removed, and disposal destination. This documentation is required by most Minnesota municipalities and the MPCA for regulatory compliance, and is essential during health department inspections. Keep service records for at least 3 years.

Yes — we service commercial grease traps and interceptors for restaurants, cafeterias, school cafeterias, hotel kitchens, bakeries, food manufacturing facilities, and any commercial operation with a commercial kitchen in our Minnesota service area. We can set up recurring service schedules to keep you compliant without you having to think about it.

Yes. For food service operations that require regular cleaning, we offer monthly and quarterly service contracts that lock in scheduling and provide reduced per-visit rates compared to on-call service. A contract ensures your trap is cleaned on a consistent schedule — which matters for compliance purposes because inspectors look for documented service records showing regular intervals, not just one recent cleaning. Contracts can cover single-unit traps, exterior interceptors, or a combination of both.

Minnesota health departments and municipal sewer authorities primarily review two things during grease trap inspections: the physical condition of the trap (is it operational and structurally intact) and the service documentation (are there records showing cleaning was performed at regulatory-required intervals with waste properly manifested). Traps found full or non-functional at the time of inspection — regardless of prior service history — typically result in a compliance order requiring immediate service. Inspectors in most Minnesota municipalities follow the 25% rule: the combined FOG and solids layer should not exceed 25% of the trap's liquid capacity.

For exterior grease interceptors (the large buried tanks), service starts with locating and opening all access lids — typically 2–3 lids on a multi-chamber interceptor. We pump the liquid contents, then break up and remove the hardened grease cap layer from the surface. The interior surfaces and any baffles are inspected for structural integrity. After pumping, we document the volume removed and the disposal destination on a waste manifest, which is given to you for your compliance file. Service typically takes 60–120 minutes depending on tank size and the volume accumulated.
