A commercial grease interceptor is not a household septic tank. It has a different waste stream, disposal path, access pattern, and service interval. Tell us the kitchen type, device size, compartments, last service, and sewer provider before dispatch.
We identify the device before sending a truck
A small indoor hydromechanical unit and a buried gravity interceptor need different equipment. Give us the rated capacity, cover location, compartment count, parking limits, access hours, and whether the kitchen is operating during service.
Idaho’s domestic-septage definition excludes commercial and industrial wastewater, including grease trap waste. The contractor needs the vehicle, receiving site, and authority that apply to this load.
Every accessible compartment gets cleaned
We remove the floating cap, liquid, and settled bottom material. Then we check accessible inlet and outlet fittings, tees, walls, and covers. Skimming the surface or pumping only the first compartment leaves waste behind.
The ticket should record the service date, volume, compartments opened, condition notes, and disposal information required for the route. Photograph defects before the lids go back on.
The kitchen sets the interval
Menu, seating, operating hours, cleaning habits, temperature, and interceptor size change how fast grease accumulates. Prior tickets and measured layers show the actual pattern better than one interval for every restaurant.
Keep sink strainers in place, scrape cookware, store fryer oil separately, and train staff to report slow floor sinks. Hot water and chemicals can move grease into the sewer without removing it from the wastewater system.
Pumping may not clear the kitchen line
An overfull interceptor can restrict the outlet, but hardened grease may remain in the inlet or building sewer after the vessel is empty. We check flow before closing the job and quote line cleaning separately when needed.
Indoor overflow cleanup is a different sanitation job. Stop kitchen discharge, isolate the affected area, and follow food-safety requirements before reopening.
Tell us which sewer system receives the flow
A Boise mailing address may use a neighboring sewer district with its own fats, oils, and grease rules. We do not apply household septic instructions to every commercial interceptor.
Call (208) 297-2198 with the address, kitchen type, device size, compartments, access hours, last ticket, backup or odor, and sewer provider. The dispatcher confirms whether the routed contractor can accept the waste.
