Running a commercial kitchen in Louisville? Staying on top of grease trap cleaning keeps you out of a sewer backup and compliant with Kentucky's FOG rules. Here's what it costs in Louisville, 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 Louisville

Louisville 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 Louisville

Clean when FOG and food solids exceed 25% of water-depth capacity; annual Form A (interceptors) or Form B (traps) certification by an MSD-certified hauler (under MSD Discharge Regulations; MSD FOG Guidelines (2019)). 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.
