Grease Trap Cleaning in Louisville, KY: Cost, Rules & Top Companies (2026)
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 size | Typical 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.
