Grease Trap Cleaning in Oklahoma City, OK: Cost, Rules & Top Companies (2026)
Running a commercial kitchen in Oklahoma City? Staying on top of grease trap cleaning keeps you out of a sewer backup and compliant with Oklahoma's FOG rules. Here's what it costs in Oklahoma City, 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 Oklahoma City
Oklahoma City 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 Oklahoma City
Minimum every 90 days or at 25% full, whichever is first; 100% pump-out required (under OAC 252:623-5-2; OKC Sewer Use Ordinance). 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.
