Grease Trap Cost Estimator
Get a Florida-specific cost estimate. All prices reflect current FL commercial plumbing market rates including labor, materials, and county permitting fees. Steps: trap type, kitchen size, situation, FL region.
Which type of grease trap is right for your Florida kitchen?
Hydromechanical units install under the sink using passive baffles to separate grease by gravity. They are compact and cost-effective for small cafes, delis, and bars. However, many Florida counties do NOT allow hydromechanical units for high-volume kitchens (150+ seats). Always confirm with your local FOG program before purchasing.
In-ground passive interceptors (concrete or fiberglass, buried outside or below floor) are the most widely accepted type across all Florida county FOG programs. They require excavation but deliver large capacity, 20-30 year service life, and meet all FL Administrative Code sizing requirements when correctly specified by a licensed plumber.
AGRUs use motorized skimmers or heating elements to continuously remove FOG from wastewater. Excellent for high-volume operations with limited outdoor space. They require electrical connections and mechanical maintenance, and must be permitted as an alternative interceptor in many FL counties.
Outdoor vault interceptors are large pre-cast concrete or fiberglass structures buried outside the building. Required by most FL counties for restaurants over 150 seats, hotels, hospital kitchens, and commercial cafeterias. They offer the highest capacity and lowest per-gallon maintenance cost over their 30-50 year lifespan.
Why kitchen volume determines your FL trap size
Florida Administrative Code Chapter 64E-6 requires interceptor sizing to be calculated using drainage fixture units (DFUs) connected to the grease system, plus a minimum grease retention time. As a rule of thumb, each 5 gallons per minute (GPM) of required flow rate needs roughly 25 gallons of trap capacity.
Undersized traps are the single most common FOG violation cited by Florida county health inspectors. An undersized trap fills faster, discharges grease into the municipal sewer prematurely, and can result in an immediate notice of violation, emergency pump-out orders, and daily fines from $500 to $10,000. Proper sizing at installation is always cheaper than retrofitting or fines later.
How your situation affects total cost in Florida
New installations require full permitting, excavation (for in-ground units), drain tie-in, backfill, and paving restoration where applicable. Budget 2-4 weeks for permit approval in Miami-Dade and Broward Counties. Some FL counties require a pre-installation site inspection by the utility FOG program before permit issuance.
Replacements run 10-15% less expensive because drain connections and permit history already exist. However, if the old trap was illegally undersized or soil around it has FOG contamination, remediation costs may partially offset savings. Always have the old unit properly decommissioned per FL DEP requirements.
Adding a second unit requires a new hydraulic flow calculation to balance drainage between both interceptors, plus separate excavation and plumbing tie-ins. Common in restaurants that have expanded seating beyond what the original trap was designed to handle.
Pump-out only pricing reflects service by a licensed FL waste hauler, manifest documentation required by state law, and a basic visual inspection of trap condition. Prices vary by trap volume (gallons pumped) and hauler travel distance.
Why FL region affects your project cost
Licensed commercial plumber labor rates vary significantly across Florida. South Florida (Miami-Dade, Broward, Palm Beach) commands a 15-20% premium due to higher cost of living, greater contractor demand, and more complex county permit requirements. Broward and Miami-Dade also impose additional environmental review fees and utility connection surcharges that add 5-10% to total project cost.
SW Florida (Lee, Collier, Sarasota) has seen rapid growth-driven demand, pushing labor rates 15% above the statewide average. Fewer FOG-specialized contractors in this market also extends scheduling timelines. The Panhandle runs 10-12% below average but may have longer lead times for specialty materials. Jacksonville and NE Florida run approximately 8% below the statewide average.
FL FOG Laws & Sizing Guide
Florida-specific regulations, sizing requirements, and county ordinances every food service operator and property manager needs to know. Sizing is governed by Florida Administrative Code Chapter 64E-6 and PDI G101 standards; all sizing must be confirmed by a FL-licensed engineer or master plumber for permitted installations. Dual compartment interceptors may be required for kitchens with pre-rinse spray valves, dishwashers, and multiple fryers operating simultaneously. Where state and local requirements differ, the more stringent standard applies. A manifest is a written record of pump-out service (date, volume removed, hauler license number, disposal facility address); FL law requires retention for 3 years minimum, and several counties require electronic submission within 15-30 days of each pump-out.
FOG Compliance Checklist
Track your Florida FOG compliance status (16-item checklist). Full compliance protects your food service permit and shields you from county fines and emergency shutdowns.
What Your Compliance Score Means
- 0-4 items (0-25%) — High Violation Risk: Operation likely does not meet FL FOG standards. A county inspector could issue an immediate notice of violation, corrective action order, or stop-service order. Contact a licensed FL plumber for an emergency compliance audit.
- 5-10 items (31-62%) — Moderate Risk: Basic practices in place but significant gaps. Most inspectors will identify multiple deficiencies during routine inspection. Schedule a professional FOG review within 30 days.
- 11-14 items (69-87%) — Good Standing: Strong compliance intent with only minor gaps. Address outstanding items promptly for full legal protection.
- 15-16 items (94-100%) — Excellent Compliance: Meets or exceeds FL FOG standards. Maintain scheduled pump-outs, keep manifests current, document annual licensed plumber inspection.
FL Pump-Out Frequency Guide
Minimum recommended frequencies for FL commercial food service kitchens. Many counties require more frequent service based on actual grease generation rate. High-volume fryer operations may require service more often.
⚠️ Florida's 25% Rule: Most FL county FOG programs enforce the "25% rule" — if the combined depth of the floating grease cap plus settled bottom solids exceeds 25% of the total liquid depth of the trap, it must be pumped immediately regardless of schedule. Keep a long measuring rod or dipstick near your trap access port. Document each manual check with date and measurement reading to demonstrate proactive compliance. Many operators check their traps weekly during slow business periods.
