Grease Trap Cleaning in Nashville, TN

It depends on kitchen volume and trap size, but most full-service Nashville restaurants need pumping every 1-3 months. Metro Water Services' general guidance is to service a trap before it's 25% full of grease and solids -- for a high-volume kitchen that can mean monthly service, while a smaller cafe might get away with quarterly. A local contractor can recommend a schedule based on your actual usage.

Metro Water Services can issue violation notices, fines, or in serious cases require a kitchen to stop discharging until the issue is corrected. Common violations include an undersized trap for the kitchen's volume, missed service intervals, or missing service documentation. A compliance-focused contractor can help you understand exactly what's required for your permit.

Small under-sink traps can sometimes be scraped out by kitchen staff between professional services, but larger in-ground interceptors require pumping equipment and proper FOG waste disposal that most restaurants aren't set up to handle themselves. Metro Nashville also requires documented service records from a permitted hauler for larger interceptors -- DIY cleaning typically doesn't satisfy that requirement.

A lingering odor after pumping often means the trap's interior walls and baffles weren't fully cleaned, just the liquid contents removed, or that grease has built up in the drain lines leading to the trap. Ask whether your service included interior cleaning, not just pumping, and consider a hydro jetting pass if the smell is coming from the line itself.
