Nashville Grease Trap & Interceptor Requirements for Restaurants

Nashville Grease Trap Regulations & Local Code Requirements

Nashville restaurants must comply with Metro Public Health Department rules outlined in the Nashville-Davidson Metro Code and the Tennessee Department of Environment and Conservation guidelines. All food service establishments are required to install appropriately sized grease traps or interceptors based on kitchen fixture count and daily operations. The size must accommodate peak volume without overflow into municipal sewer lines. Establishments are typically required to maintain a minimum 3-chambered grease trap system unless approved alternatives are in place. Inspectors verify compliance during routine health inspections and can issue citations for undersized or non-functional systems.

Pumping, Cleaning & Maintenance Schedule Requirements

Metro Public Health requires restaurants to pump and clean grease traps regularly—typically every 30 to 60 days depending on kitchen volume and trap size, though high-volume establishments may need more frequent service. Owners must maintain detailed maintenance logs documenting pump-out dates, removal amounts, and contractor information, which must be available for inspection. Grease traps should be inspected visually before each pumping to ensure proper function and identify blockages early. Failure to maintain current pump-out records or evidence of accumulated grease beyond system capacity can result in health code violations. Many Nashville restaurants contract with local waste management or grease collection services that provide documentation automatically.

Enforcement, Inspections & Violation Penalties

Metro Public Health conducts routine and complaint-based inspections at food service establishments, checking for grease trap functionality, proper signage, and current maintenance documentation. Violations for inadequate grease management can result in conditional operating permits, repeat violations, or temporary closure if sewage backup or environmental hazard risk exists. Blocked municipal sewer lines caused by grease accumulation can trigger emergency enforcement action and liability costs for the responsible establishment. Tennessee's Department of Environment and Conservation may also assess penalties if non-compliant systems impact local water quality. Keeping current pumping contracts and inspection records is the most effective defense against penalties.
