Grease trap pumping costs in Northwest Arkansas depend on two variables: the size of your grease trap and how full it is at time of service. Ozark Grease Pros prices grease trap pumping at approximately $0.40 per gallon for direct restaurant service, billed against the signed manifest volume. A 1,000-gallon trap pumped at near-capacity costs approximately $320–$400. A 1,500-gallon grease interceptor costs approximately $480–$600.
NWA restaurants benefit from one significant cost advantage over national averages: the Ozark Grease Pros recycling facility in Siloam Springs, AR is the only licensed grease recycling and processing plant in Northwest Arkansas. Because waste doesn’t need to travel 90–115 miles to Tulsa, NWA grease trap pumping costs remain lower than markets that depend on out-of-state disposal. Disposal overhead is a meaningful component of per-gallon pricing — shorter haul distance matters.
This guide covers per-gallon pricing, trap size cost breakdowns, the difference between direct service and tipping fee pricing, frequency guidance by restaurant type, and the 25% rule that governs FOG compliance in Arkansas. Last updated: 2026.
Ozark Grease Pros uses two pricing structures depending on the customer type:
Customer Type | Rate | Billed Against | Notes |
Restaurant / direct service | ~$0.40/gallon | Signed manifest | Full pump-and-clean service. Every visit includes interior scrub, baffle clearing, water refill. |
B2B hauler / tipping fee | ~$0.20/gallon | Hauler’s manifest | Other pumping companies disposing waste at our Siloam Springs facility. Billed per gallon on the service manifest. |
What the per-gallon rate includes for direct restaurant service:
The table below shows estimated pumping costs by trap size at the $0.40/gallon direct service rate. Actual cost depends on the fill level at time of service — a 1,000-gallon trap that is only 50% full at pump time costs half what a full trap costs. Most operators schedule service before reaching 25% solid accumulation per Arkansas FOG compliance guidelines.

Note: Costs are estimates at the ~$0.40/gallon base rate. Actual billing is based on manifested gallons removed. Trap size is nominal — actual capacity varies by manufacturer and installation. For large interceptors (3,000+ gallons), contact us at 479-448-7755 for specific pricing.
Ozark Grease Pros operates both as a direct grease trap service provider for restaurants and as a licensed disposal facility for other pumping companies (the ‘tipping fee’ model). These are distinct service relationships with different pricing:
Model | Who Uses It | Rate | How It Works |
Direct restaurant service | Restaurants and food service operators | ~$0.40/gal | Ozark Grease Pros pumps your grease trap, provides cleaning, signs manifest. You pay per gallon on the manifest. |
B2B tipping fee | Other pumping companies, haulers | ~$0.20/gal | Your pumping company brings grease trap waste to our Siloam Springs, AR facility for processing. Billed per gallon on the haul manifest. |
The tipping fee structure is relevant for restaurant operators who already have a pumping company under contract: if that company’s disposal destination is Tulsa (90–115 miles) and there is a closer NWA facility available, it may be worth asking your pumping company whether they dispose at Ozark Grease Pros — shorter haul can translate to lower per-gallon overhead, depending on the company’s pricing model.
Before Ozark Grease Pros opened the only licensed grease recycling facility in Northwest Arkansas, NWA pumping companies had to haul grease trap waste to Tulsa or Little Rock — both 90–120 miles from the NWA metro. That disposal haul distance is embedded in per-gallon pricing. The table below shows approximate haul distances from NWA cities to our Siloam Springs facility vs. the Tulsa alternative:
NWA City | To Siloam Springs (Our Facility) | To Tulsa | Distance Saved | Notes |
Siloam Springs | 0 miles (facility location) | ~95 miles | 95 miles | Our licensed facility is here. |
Gentry, AR | ~7 miles | ~100 miles | ~93 miles | Closest NWA city to facility. |
Elm Springs, AR | ~17 miles | ~90 miles | ~73 miles | AR-412 direct route. |
Centerton, AR | ~22 miles | ~103 miles | ~81 miles | Between Bentonville and facility. |
Bentonville, AR | ~30 miles | ~105 miles | ~75 miles | |
Rogers, AR | ~26 miles | ~100 miles | ~74 miles | |
Springdale, AR | ~25 miles | ~95 miles | ~70 miles | I-49 corridor. |
Fayetteville, AR | ~28 miles | ~95 miles | ~67 miles | |
Bella Vista, AR | ~30 miles | ~115 miles | ~85 miles |
Shorter haul distance means lower disposal overhead for the pumping company. Whether and how that translates to lower restaurant pricing depends on each provider’s cost structure. What it does mean with certainty: NWA grease trap waste pumped by Ozark Grease Pros stays within Arkansas — processed at our ADEQ-licensed facility rather than transported to an out-of-state disposal site.
Grease trap pump frequency depends on two factors: trap size relative to kitchen output, and the type of cooking. High-frying operations produce more FOG faster. The table below provides frequency guidelines based on restaurant type:
Restaurant Type | Trap Size | Recommended Frequency | Notes |
QSR / fast food (high frying) | 500–1,000 gal | Monthly | Chicken, burgers, fries — daily frying volume fills traps quickly. Monthly service prevents the odor cycle. |
Casual dining / pizza | 500–1,500 gal | Bi-monthly | Moderate FOG output. Bi-monthly service is typically appropriate unless high chicken/frying menu. |
Fast-casual (moderate frying) | 500–1,000 gal | Monthly–bi-monthly | Confirm fill rate after first service. Fast-casual with significant frying trends toward monthly. |
Fine dining / low-frying menu | 500–1,000 gal | Quarterly | Lower FOG output allows less frequent service. Confirm with first baseline assessment. |
Institutional / hospital / campus | 1,500–2,000+ gal | Monthly–bi-monthly | High volume, consistent output. Compliance documentation requirements typically call for regular scheduled service. |
New restaurant — first service | Any | Assessment pump | First visit: assess trap condition, confirm sizing adequacy, establish baseline before setting ongoing schedule. |
Quick frequency reference:
Arkansas ADEQ and most Arkansas municipal water utilities — including the City of Fayetteville, City of Rogers, City of Bentonville, City of Springdale, and others across NWA — follow the 25% rule as the standard FOG compliance threshold:
THE 25% RULEA grease trap must be pumped when the combined depth of floating grease and settled solids reaches 25% of the trap’s total liquid depth. Exceeding the 25% threshold is typically a FOG compliance violation subject to citation by city water utilities and Benton/Washington County health inspectors. |
Practical implication: a 1,000-gallon trap becomes non-compliant when grease and solids together exceed 250 gallons combined depth. At the $0.40/gallon rate, a 1,000-gallon trap pumped at the compliance threshold (250 gallons accumulated) costs approximately $100 per pump — significantly less than pumping at full capacity ($320–$400). Regular service before the 25% threshold keeps compliance costs predictable.
Using the $0.40/gallon rate, the 25% rule threshold, and typical frequency patterns, here are estimated annual grease trap service costs by restaurant type:
Restaurant Type | Trap Size | Pumps/Year | Est. Gallons/Year (removed) | Est. Annual Cost |
QSR / fast food | 1,000 gal | 12 (monthly) | ~6,000–9,600 gal | ~$2,400–$3,840/yr |
Casual dining | 1,000 gal | 6 (bi-monthly) | ~3,000–4,800 gal | ~$1,200–$1,920/yr |
Fast-casual | 750 gal | 8–12 | ~3,000–5,400 gal | ~$1,200–$2,160/yr |
Fine dining | 750 gal | 4 (quarterly) | ~1,500–2,250 gal | ~$600–$900/yr |
Large restaurant | 1,500 gal | 6–12 | ~5,400–10,800 gal | ~$2,160–$4,320/yr |
Annual costs above are estimates. Actual costs depend on trap fill rate, kitchen volume changes, and whether service frequency adjusts as operations change. For an accurate estimate specific to your NWA restaurant, call 479-448-7755.

Ozark Grease Pros operates the only licensed grease recycling facility in Northwest Arkansas, in Siloam Springs, AR. NWA restaurants are typically 20–40 miles from our facility, compared to 90–115 miles to Tulsa disposal sites. Shorter haul distance reduces per-gallon disposal overhead and keeps NWA grease trap pumping costs lower.
High-frying QSR operations typically need monthly pumping. Casual dining with moderate FOG output typically needs bi-monthly to quarterly service. The 25% rule — pump when the trap is 25% full of grease and solids — is the standard FOG compliance guideline in Arkansas.
Arkansas ADEQ and most Arkansas municipal water utilities follow the 25% rule: a grease trap should be serviced when the combined depth of floating grease and settled solids reaches 25% of the trap’s liquid depth. Exceeding this threshold is typically a FOG compliance violation.
At Ozark Grease Pros, full interior cleaning — wall scrubbing, baffle clearing, residual solids removal — is included on every service visit. This is combined pump-and-clean service, not pump-only. The $0.40/gallon rate covers complete service.
