Running a commercial kitchen in Detroit? Staying on top of grease trap cleaning keeps you out of a sewer backup and compliant with Michigan's FOG rules. Here's what it costs in Detroit, how often you're required to clean, the permit and regulation basics, and the local companies that handle it.

What Grease Trap Cleaning Costs in Detroit

Detroit prices near the national baseline; dense provider competition across the metro keeps rates competitive.

Trap / interceptor sizeTypical cost per service
Small trap (under 50 gal)$115 – $240
Medium trap (50–500 gal)$150 – $475
Large interceptor (500–1,500 gal)$400 – $1,200
Large interceptor (1,500+ gal)$475 – $2,500

Typical ranges per service — your price depends on trap size, accessibility, and frequency. Recurring contracts usually run 15–30% below one-off rates. Estimate yours with the cost estimator or see the full pricing guide.

How Often You Must Clean It in Detroit

State law sets no universal cleaning interval — that's governed by local municipal pretreatment programs. State rules focus on the waste side: licensed haulers must track food establishment septage separately, and if it's land-applied it must be blended no richer than 1 part FES to 3 parts domestic septage. The industry-standard 25% rule applies either way: clean before fats, oils, and grease reach a quarter of your trap's capacity, because past that point grease passes straight through to the sewer. High-volume kitchens (fryers, BBQ, seafood) often need service more often than the minimum.
