Grease trap service typically costs $100-$400 for a routine indoor-unit cleaning and $300-$900 or more for a large outdoor interceptor. Grease trap service cost depends mainly on capacity, how full the unit is, access for the pump truck, disposal charges, and local labor rates.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Small indoor trap | $100 | $175 | $300 | About 20-50 gallons |
| Medium indoor trap | $175 | $275 | $450 | About 50-100 gallons |
| Outdoor interceptor | $300 | $600 | $1,200+ | Often 500-1,500 gallons |
| Annual service budget | $400 | $1,200 | $4,800+ | Depends on size and service frequency |
Typical grease trap service prices by capacity
For a standard pump-out and cleaning, a 20-50-gallon under-sink trap commonly costs $100-$250 per visit. A 50-100-gallon unit often runs $175-$400, while a 500-1,500-gallon outdoor interceptor generally costs $300-$900. Oversized units or difficult jobs can exceed $1,200.
A reasonable planning average is about $200-$300 for a small indoor unit and $500-$700 for an accessible outdoor interceptor. These estimates assume routine service, ordinary access, and no repair work. A per-gallon quote is not always comparable: providers may have minimum charges, travel fees, or disposal costs regardless of tank size.
Assumptions: U.S. market ranges for routine pumping and cleaning, standard access, and no major blockage or repair.
What parts make up a pump-out invoice?
A service quote may include pumping, scraping or washing the trap, hauling waste, and documenting the work. Ask whether the quoted amount covers complete removal of grease and solids, rather than only pumping liquid from the unit.
| Quote component | Typical charge | What affects it | Often included? |
|---|---|---|---|
| Labor | $75-$150 per hour | Time, crew size, cleaning scope | Usually |
| Pump truck and equipment | $50-$200 per visit | Truck size and hose reach | Sometimes |
| Waste hauling and disposal | $25-$150 | Volume and local disposal rates | Varies |
| Access or service surcharge | $25-$250 | Blocked lids, long hose runs | Usually not |
Labor is commonly bundled into a flat service price, so line items are not always shown.
How do gallons and access change the quote?
Capacity is a major price driver: a 1,000-gallon interceptor usually costs more to pump than a 50-gallon indoor trap because it holds more waste and takes longer to empty. A unit that is unusually full, overdue, or packed with hardened solids can also require extra cleaning time or more than one disposal load.
Access matters as much as capacity. A truck parked within 50 feet of an accessible lid may be covered by the standard rate; a hose run over 100 feet, a locked enclosure, or a lid beneath pavement can add roughly $50-$250. If the lid must be uncovered or heavy equipment brought in, request a separate price before scheduling.
Confirm the tank’s gallon capacity and the distance from the truck parking area to the service opening before accepting a quote. Those details help providers price the job more accurately.
What will service cost in three restaurant scenarios?
These examples show how unit size and service conditions change the total. Rates are illustrative; location and provider pricing can shift them.
| Scenario | Service scope | Estimated total |
|---|---|---|
| Café with 35-gallon trap | One technician, 1 hour, routine pump-out | $125-$225 |
| Busy diner with 75-gallon trap | Cleaning, disposal, moderate grease buildup | $225-$400 |
| Restaurant with 1,000-gallon interceptor | Truck pump-out, 2-3 hours, standard access | $450-$850 |
Assumptions: Routine weekday appointments, ordinary access, and no repairs or emergency response.
Regional labor rates shift grease interceptor prices
Prices may run 15%-30% above typical estimates in dense coastal metros, where labor, disposal, and truck operating costs are higher. Smaller cities and rural areas may be 10%-20% below metro rates, although long travel distances can erase the savings or trigger a trip charge.
In parts of California, the Northeast, and major urban markets, small-trap visits may reach $250-$450 and large-interceptor service may exceed $1,000. In lower-cost regions, an accessible indoor trap may be closer to $100-$200. These are broad comparisons, not fixed regional tariffs; local wastewater rules and disposal facilities also affect quotes.
How long does pumping take, and what causes extra fees?
A straightforward indoor trap service often takes 30-60 minutes. A larger interceptor commonly takes 1-3 hours, including setup, pumping, cleaning, and documentation. Hourly labor charges may apply when the unit is badly clogged or the work requires additional crew time.
After-hours or emergency service can add 25%-100% to the normal rate. Other possible charges include $25-$100 for a missed appointment, $50-$250 for difficult access, and repair costs for damaged lids, baffles, or piping. Ask whether the provider charges for inspection or service records separately.
Cleaning frequency and annual grease trap budget
Many food-service businesses schedule a small trap every 1-4 weeks, while some larger interceptors are serviced every 1-3 months. The right interval depends on kitchen volume, grease output, tank capacity, and local requirements. A high-volume kitchen may need more frequent pump-outs even with a large interceptor.
At $150-$250 per indoor service, monthly visits add up to about $1,800-$3,000 per year. Quarterly service at $400-$700 per outdoor visit totals roughly $1,600-$2,800 annually. Budget by expected visits per year, not by the lowest single-service quote. Service records can also help identify whether the interval is appropriate.
Which service choices lower the bill without risking backups?
Compare at least three written quotes using the same tank capacity, cleaning scope, access details, and disposal requirements. A lower pump-only price may not include scraping, washing, or waste hauling, so compare the final amount and included tasks rather than the starting rate.
Keeping the service opening accessible and scheduling routine visits can reduce labor and emergency charges. Scrape food waste into the trash, use sink strainers, and avoid pouring cooking oil into drains; these steps may slow buildup but do not replace pumping. Avoid extending service intervals beyond local rules or the provider’s findings, since backups and emergency cleanup can cost more than planned maintenance.
Choose a clearly itemized routine service and control access and scheduling before cutting cleaning frequency.
