Grease Trap Cleaning in Charleston, WV: Cost, Rules & Top Companies (2026)
Running a commercial kitchen in Charleston? Staying on top of grease trap cleaning keeps you out of a sewer backup and compliant with West Virginia's FOG rules. Here's what it costs in Charleston, 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 Charleston
Charleston 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 Charleston
No statewide cleaning interval could be confirmed — the state grease statute (§16-6-22b) focuses on physically securing outdoor grease trap covers. Local municipalities set cleaning frequency through their own FOG ordinances. 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.

| State regulator | West Virginia Department of Environmental Protection (WVDEP), Division of Water and Waste Management (+ WV Dept. of Health for food establishment inspections) |

Always get a signed manifest at every service and keep your records — that's the proof inspectors ask for. For the full West Virginia breakdown (hauler licensing, record retention, state penalties), see the West Virginia grease trap regulations guide.
