Nashville commercial kitchens are subject to FOG (fats, oils, grease) discharge permits and periodic inspection by Metro Water Services. A compliance inspection checks trap sizing, condition, and service records against what's required for your permit. Falling out of compliance can mean fines or a forced closure of drain lines until the issue is fixed.

Common Grease Trap Inspection & Compliance situations in Nashville

Slow-draining sinks in a commercial kitchen

This is usually the earliest sign of grease buildup approaching the 25% threshold — addressing it before a full backup avoids unplanned downtime.

No documented cleaning schedule or service records on file

Most jurisdictions require several years of retained service records — a missing paper trail is a common, avoidable compliance finding during an inspection.

Recent increase in kitchen volume or menu changes involving more fried or greasy food

Higher grease volume means the 25% threshold gets reached faster — worth adjusting the cleaning schedule rather than waiting for a backup to signal the change.
