Grease Trap Cleaning Tampa uses the City of Tampa's own figures for grease trap installation cost: $250–$1,500 installed for a small trap of 0–100 gallons, and $4,000–$8,500 installed for a new 750–1,500 gallon grease interceptor. Excavation, piping runs, permits and site access move the final number within or beyond those ranges.
Installed cost, from the City of Tampa
The City of Tampa’s grease ordinance FAQ gives two installed-cost ranges. They’re official figures, so they carry high confidence:
| Unit | Installed cost |
|---|---|
| Small grease trap, 0–100 gallons | $250–$1,500 |
| New grease interceptor, 750–1,500 gallons | $4,000–$8,500 |
What moves the final number
- Excavation and restoration. Interceptors go in the ground, often under paving that has to be cut and replaced.
- Piping. Every grease-producing fixture has to drain through the unit, and restroom waste has to stay out of it. Re-routing lines in an existing kitchen adds cost.
- Venting and flow control. Indoor traps need a flow-control device and a vent ending at least 6 inches above the flood rim (Tampa Code Sec. 26-306(f)).
- Permits and design. A permit application with design criteria to the Florida Building Code – Plumbing.
- Access and downtime. Night or closed-day work to keep the kitchen running.
When the City can require a new unit
An existing facility can keep its current trap if it’s in good operating condition. Under Tampa Code Sec. 26-306(b)(2), the City can require a new trap or interceptor, or a repair, when:
- the facility contributes enough grease to cause line stoppages
- wastewater grease exceeds 400 mg/l in the inspector’s sampling
- there is no trap or interceptor
- the existing unit is defective or can’t be repaired
- remodelling requires a plumbing permit
- the facility is sold or changes ownership
- fixtures aren’t connected to the unit as required
That last-but-one trigger is why buyers should inspect the grease trap before closing. Clearwater has a similar rule: non-compliant interceptors must be upgraded or replaced within 180 days of notice (City Code Sec. 32.189).
Sizing comes first
Sizing follows the Florida Building Code – Plumbing, based on the fixtures that drain to the unit and their flow. The City of Tampa publishes a grease trap sizing calculator, and Hillsborough County directs owners to a licensed commercial plumber. Buying a unit before sizing is confirmed is how kitchens end up installing twice. See grease trap installation and grease trap vs grease interceptor.
Don’t forget the running cost
Installation is a one-off. Pumping is forever. A 1,000–1,500 gallon interceptor costs about $400–$650 per pump-out, and between 4 and 13 pump-outs a year depending on your jurisdiction. See the interceptor pumping cost guide.
Bottom line
Budget $250–$1,500 for a small indoor trap or $4,000–$8,500 for a 750–1,500 gallon interceptor, plus permits and any site work. Get the requirement and sizing confirmed before buying a unit. To talk it through, call (727) 476-9241.
