Avg. Cost

Grease trap pumping is a critical maintenance service for restaurants, commercial kitchens, food processing facilities, and any business that discharges fats, oils, and grease (FOG) into its wastewater. Grease traps (also called grease interceptors) capture FOG before it enters the sewer system or septic tank, where it would cause devastating clogs and backups. Local health codes and environmental regulations typically require grease traps to be pumped when the combined grease and solids layer reaches 25% of the trap's capacity — for busy restaurants, this often means pumping every 1 to 3 months. During service, a vacuum truck removes all contents from the trap, including the floating grease layer, settled food solids, and wastewater. The technician will scrape the trap walls, inspect baffles and flow restrictors, and verify the trap is functioning correctly before refilling with clean water. Failure to maintain grease traps can result in sewer backups, foul odors, health department citations, fines of $1,000 or more per violation, and even forced closure. Many jurisdictions require businesses to maintain a pumping log and produce records during health inspections. Professional grease trap services often include manifesting and proper disposal of collected waste at approved facilities.

Florida Regulations for Grease Trap Pumping

Florida regulates septic systems through the Florida Department of Environmental Protection (DEP) and county health departments. In a major regulatory shift, DEP assumed direct oversight of septic systems in 16 priority counties as part of the 2024 Basin Management Action Plans (BMAPs). These counties — including parts of the Tampa Bay, Indian River Lagoon, and Springs Coast watersheds — now require Enhanced Nutrient Reduction (ENR) systems for new installations and major repairs. All septic installations require permits from the county health department, a site evaluation, and inspections at multiple stages. Florida mandates a minimum of 24 inches of unsaturated soil below the drain field bottom — a challenging requirement given the state's notoriously high water tables, which can be as shallow as 12 inches below grade in coastal areas. Systems must be set back 75 feet from wells and 50 feet from surface water. The state requires septic inspections for real estate transactions in many counties.

Licensing Requirements

Florida requires septic system contractors to be registered with the Department of Health. Master Septic Tank Contractor licenses require passing a state exam, demonstrating financial responsibility, and carrying liability insurance. Septic tank pumpers must obtain a Registration Certificate from the county health department and maintain proper waste disposal documentation. All contractors must complete continuing education to maintain their registration.

Environmental Considerations

Florida's biggest septic challenge is its high water table — in many coastal and central areas, groundwater sits just 12 to 24 inches below the surface, severely limiting conventional drain field options. Sandy soils in most of the state provide excellent percolation but minimal treatment, raising concerns about nutrient loading into springs, lakes, and the Indian River Lagoon. The new BMAP regulations represent the state's most aggressive effort to address septic nutrient pollution, requiring nitrogen-reducing systems that can cost two to three times more than conventional installations. Hurricane and flood damage to septic systems is a recurring issue in coastal counties.

Signs You Need Grease Trap Pumping

Slow drains in the kitchen, especially floor drains and sink drains

The Grease Trap Pumping Process

1 Access the grease trap and remove the lid for inspection
2 Measure the grease and solids accumulation levels
3 Pump out all contents — grease, solids, and wastewater — with a vacuum truck
4 Scrape trap walls, baffles, and lid to remove adhered grease
5 Inspect baffles, flow control devices, and trap integrity
6 Refill with clean water, document the service, and provide compliance records

Frequently Asked Questions — Grease Trap Pumping in Florida

How often does a grease trap need to be pumped?

The industry standard is the 25% rule: pump when combined grease and solids reach 25% of trap capacity. For most restaurants, this means every 1-4 weeks for small under-sink traps (20-50 gallons) and every 1-3 months for large exterior interceptors (1,000-2,000 gallons). Many jurisdictions mandate pumping at least every 90 days regardless of accumulation levels.

How much does grease trap pumping cost?

Costs depend on trap size: small under-sink traps (20-50 gallons) cost $75-$250 per pumping, medium exterior traps (200-500 gallons) cost $150-$400, and large interceptors (1,000-2,000 gallons) cost $300-$800. Scheduled service contracts reduce per-visit cost by 20-35% compared to on-demand calls. Annual grease trap maintenance for a typical restaurant runs $2,000-$6,000.

What happens if I do not pump my grease trap?

Neglected grease traps cause sewer line blockages, foul odors, health department citations ($250-$10,000 per violation), potential temporary closure orders for repeat violations, and sewage backups into your kitchen. For restaurants on septic systems, grease entering the tank causes accelerated scum buildup, outlet blockage, and premature drain field failure ($10,000-$25,000 to replace).

Do I need a grease trap if my restaurant is on septic?

Absolutely — and sizing should be more generous than minimum requirements. Grease that bypasses or overwhelms the trap enters your septic tank, where it accumulates faster than bacteria can break it down. This leads to scum layer buildup, blocked baffles, and grease reaching the drain field where it permanently clogs soil pores. Restaurants on septic should also pump their septic tank annually rather than the standard 3-5 years.
