## Commercial Septic Tank, Grease Interceptor & Holding Tank Pumping Rates (2026)

Restaurants, commercial kitchens, RV parks, mobile home communities, and industrial sites without municipal sewer connections require high-capacity vacuum trucks (2,500 to 5,000+ gallons) and strict **FOG (Fats, Oils, and Grease) manifest documentation** for city and county pretreatment inspectors.

| Commercial Liquid Waste Service | Volume / Unit Type | Recommended Frequency | 2026 Typical US Cost |
| :--- | :--- | :--- | :--- |

## What Full-Service Commercial Grease & Septic Hauling Includes

- **100% Pump-Down & Sidewall Scraping:** Not just skimming the top grease cap ("pump and return" is illegal in most US jurisdictions)—the entire interceptor is pumped dry, walls and baffles are scraped clean, and the odour trap is verified.
- **Digital Municipal FOG & EPA Manifests:** Official trip tickets recording gallons removed, interceptor condition (% FOG vs solids), and receiving treatment plant permit numbers.

Select **2,000+ Gallon / Commercial Grease Trap** in our instant ZIP calculator above for commercial fleet pricing.
