TL;DR
In Arkansas, grease trap pumping runs $250 to $600 per service visit, and installing a new interceptor costs $1,500 to $8,500 or more depending on size and whether you need a concrete in-ground unit. You also need a state-issued Liquid Waste Transporter permit for any hauler you hire, and most municipalities require a local pretreatment permit before you open. Budget 4 to 12 weeks for permit approval.
What does a grease trap actually cost in Arkansas?
Here's the short answer. Pumping costs $250 to $600 per visit for a typical restaurant-sized trap. Buying and installing a new interceptor runs from $1,500 for a small under-sink polyethylene unit to $8,500 or well beyond for a large concrete in-ground vault with labor and inspection fees baked in. Neither figure is padded. They reflect real regional contractor quotes from public bid documents and industry cost surveys.
Why the wide range? A 50-gallon hydromechanical interceptor bolted under a prep sink in a food truck commissary is a one-afternoon job. A 2,000-gallon concrete vault buried in a restaurant parking lot needs excavation, concrete pouring, plumbing connections, and a city inspector sign-off before you serve a single plate. Those two jobs are not the same thing, and the price gap reflects that.
Arkansas does not publish a state-mandated fee schedule for grease trap installation or pumping. Prices are set by the hauler or plumber. Get at least three quotes. Ask each one to break out material, labor, and disposal separately. The disposal line is where surprises hide.

Do you need a license for grease trap work in Arkansas?
Yes. Three separate licenses touch grease trap operations in Arkansas, and they land on three different parties.
Start with the hauler. Any company that pumps your trap and hauls the waste is a liquid waste transporter under Arkansas law. The Arkansas Department of Health (ADH) issues Liquid Waste Transporter permits under Arkansas Code Annotated Title 14, Chapter 236, which governs the handling and disposal of septage and grease waste [1]. A hauler operating without that permit is breaking state law, and hiring an unlicensed one can expose your business to liability if the waste gets dumped illegally.
Next, the installer. Arkansas requires a licensed plumber for any plumbing work that connects to the sanitary sewer, which a grease interceptor always does. The Arkansas State Board of Plumbing Examiners issues contractor licenses and sets journeyman and master plumber requirements [2]. Verify your installer's license number before you sign anything.
Third, your facility. Most Arkansas municipalities with a pretreatment program require food service establishments to hold a local industrial pretreatment permit or wastewater discharge permit before they can legally discharge grease-laden wastewater. The Arkansas Department of Energy and Environment, Division of Environmental Quality, administers the state's National Pollutant Discharge Elimination System (NPDES) pretreatment rules, and local publicly owned treatment works (POTWs) run those rules at the municipal level [3]. If your city or county has a pretreatment program, you apply to that local authority, not the state, for your facility permit.
So the hauler needs an ADH transporter permit, the installer needs a plumbing contractor license, and your restaurant likely needs a local pretreatment or discharge permit. Confirm all three with the relevant board or authority before your first day open.
How long does grease trap permitting take in Arkansas?
Timelines swing hard depending on whether you're dealing with the state or a local authority, and whether your project triggers plan review. Plan for 4 to 12 weeks total on the facility side.
For a local pretreatment or wastewater discharge permit at a city-run POTW, expect 4 to 8 weeks from a complete application to an approval letter in most mid-sized Arkansas cities. Smaller municipalities often move faster because there's less queue. Larger systems, like Little Rock or Fort Smith, can run 8 to 12 weeks if your application needs engineering review or if the pretreatment coordinator asks for more information.
If your project needs a plumbing permit from the city or county building department (and installing a new interceptor almost always does), that permit typically issues in 5 to 15 business days after plan submission. Jurisdictions that require a licensed engineer to stamp the drawings add time.
The ADH transporter permitting process runs on a separate track and isn't your direct concern as the facility owner. Still, verify your hauler's permit is current before you schedule service. ADH renews those permits annually.
Nobody has published a statewide median for Arkansas grease permit timelines specifically. The 4 to 12 week bracket above is a reasonable planning window based on how Arkansas pretreatment programs generally run, but confirm current timelines directly with the relevant local authority before you commit to construction or an opening date.
What size grease interceptor does Arkansas require?
Arkansas does not publish one statewide sizing formula. Sizing comes from the applicable plumbing code and from your local pretreatment program's minimums. The code sets a floor; your city can set it higher.
Arkansas adopted the International Plumbing Code (IPC) as its statewide plumbing standard. The IPC sizes hydromechanical grease interceptors (the smaller, indoor type) under Section 1003.3 by flow rate in gallons per minute, and it sizes gravity grease interceptors (the large in-ground type) under Appendix K by liquid capacity in gallons, based on the drainage load from the kitchen fixtures connected to them [4]. The two methods are genuinely different, so make sure your plumber applies the right one.
Your local POTW or building department has the final say on minimum size. Cities with active pretreatment programs often impose minimums above the IPC baseline, especially for higher-volume kitchens. A school cafeteria or hospital kitchen feeding hundreds of people daily faces different requirements than a small sandwich shop.
Hire a licensed Arkansas plumber who has done restaurant work in your specific jurisdiction. They'll know what the local inspectors actually accept, which sometimes differs from what the code says on paper.
What are the ongoing pumping and maintenance costs in Arkansas?
After installation, maintenance is your biggest recurring line item. Here's what to plan for.
Pumping frequency depends on trap size and kitchen volume. The IPC and most local pretreatment programs recommend pumping when the trap reaches 25% capacity with grease and solids combined, though many operators run a fixed schedule of every 30, 60, or 90 days based on their waste profile [10]. Some Arkansas pretreatment permits set a minimum pumping frequency, so read your permit conditions.
For a standard 1,000-gallon in-ground interceptor, a single pump-out from a licensed transporter in Arkansas typically runs $250 to $450. For larger vaults in the 1,500 to 2,500 gallon range, expect $400 to $600 or more, especially if the hauler has to drive to an approved disposal facility far from your site.
Manifests matter here. Arkansas requires liquid waste transporters to keep records of waste pickup and disposal, and many local pretreatment programs require the facility to keep copies of those service manifests on file. If your hauler doesn't hand you a manifest for every pump-out, ask for one in writing. A missing manifest during a pretreatment inspection can turn into a notice of violation.
If you need help organizing your manifest paper trail, GreaseTrapPath's Interceptor + Manifest Kit ($199 one-time) covers the forms and tracking system in one package. Find it at /start.
Annual maintenance beyond pumping, things like inspecting baffles and inlet/outlet fittings, should run $100 to $300 per visit from a qualified plumber. Skipping that inspection is a false economy. A failed baffle lets grease pass through to the sewer, which puts you in violation of your pretreatment permit.
How does Arkansas compare to neighboring states on grease trap cost?
Arkansas sits in the lower-cost tier for grease trap work in the South and Midwest. Plumbing contractor labor in Arkansas runs below the national median, and that flows straight into lower installation quotes compared to states like Florida or Illinois [5].
Pumping costs follow the same pattern. Disposal fees at Arkansas-approved septage and grease receiving facilities are generally lower than in states with tighter disposal infrastructure.
The table below gives a rough cost comparison across installation and pumping. These are mid-range estimates for a typical full-service restaurant, not guaranteed quotes.
| State | New interceptor install (mid-range) | Single pump-out (typical) |
|---|---|---|
| Arkansas | $3,000 to $6,000 | $250 to $450 |
| Alabama | $3,500 to $7,000 | $275 to $500 |
| Georgia | $4,000 to $8,000 | $300 to $550 |
| Florida | $4,500 to $9,000 | $325 to $600 |
| Illinois | $5,000 to $10,000 | $350 to $650 |
The ranges above draw from regional plumbing contractor bid data and industry cost benchmarks [5][6]. These are planning figures, not quotes. Get local bids before you lock in a budget.

What approvals does Arkansas require before you install a grease trap?
Before a shovel hits the ground or a plumber touches a pipe, you work through a short but real approval sequence. Skip a step and you can end up digging up a buried interceptor later.
First, check with your local POTW. If your city or county runs a pretreatment program (most cities over 10,000 people do), they'll want to review the interceptor size and location before installation. Some require a pretreatment permit application before any construction begins. The Arkansas Division of Environmental Quality maintains the state's list of permitted POTWs [3].
Second, pull a plumbing permit from your local building department. In Arkansas, plumbing permits issue at the city or county level, not the state level, so the form and fee vary by jurisdiction. Expect a permit fee of $50 to $200 for a grease interceptor, though some jurisdictions charge based on the valuation of the work.
Third, schedule the rough-in and final inspections. Your building department will require a plumbing inspection before the interceptor gets backfilled or covered. Don't assume it'll be fine and skip it. An interceptor buried without inspection can require excavation later if a question comes up during a pretreatment audit.
Fourth, update your pretreatment permit or facility registration if required. Once the unit is installed and inspected, notify your local POTW and get the installation documented in your file. That piece of paper matters when an inspector shows up.
The whole sequence, from permit application to final inspection, typically takes 3 to 8 weeks for a straightforward installation at a new restaurant. Confirm current timelines with the relevant local authority.
What records does Arkansas require you to keep?
Record-keeping is where a lot of Arkansas food service operators get caught flat-footed during a pretreatment inspection. The federal floor is three years of service records.
Arkansas's pretreatment rules flow from the federal Clean Water Act pretreatment standards at 40 CFR Part 403, which require facilities subject to a local pretreatment permit to keep records of their grease trap service, including cleaning dates, volumes removed, and the name of the licensed hauler [7]. The federal program requires those records to be kept for at least three years [7].
Your local POTW may require more. Some Arkansas municipalities make you submit copies of service manifests to the pretreatment coordinator quarterly or annually. Others just want them available for inspection on request. Read your permit conditions carefully.
The manifest from your hauler should include the date of service, the address of your facility, the volume of waste removed, the vehicle license plate and transporter permit number, and the name and address of the disposal facility. If a hauler hands you a receipt missing those fields, fix that before your next inspection.
Are there Arkansas-specific rules for food trucks and mobile units?
Food trucks and mobile food units are a real gray area in Arkansas grease law. State law requires mobile food units to be inspected and permitted by the ADH under Arkansas Code Annotated Title 20, Chapter 57 [8], but grease management for mobile units gets handled differently than for fixed food service establishments.
Most mobile operators in Arkansas have to service their grease waste at an approved commissary or dump station, not on the street. That commissary must have a properly permitted grease interceptor serving its kitchen and dump station. If you run your food truck out of a permitted commissary, the commissary's grease infrastructure covers your waste stream, but you need a written agreement with the commissary that documents the arrangement.
If your truck parks at one fixed location for a big chunk of the week, some local pretreatment programs may treat it like a fixed facility and require a separate permit. Confirm this with your local POTW and with the ADH environmental health office in your county.
How to find a licensed grease trap hauler in Arkansas
The ADH issues Liquid Waste Transporter permits and keeps records of permitted haulers. Contact the ADH Division of Environmental Health Services to verify whether a hauler is currently permitted [1]. Ask the hauler for their permit number and expiration date before you schedule a pump-out.
You can also ask your local POTW pretreatment coordinator for a list of haulers they have on file. They're not legally required to hand over a referral list in most cases, but many will share one informally because it makes their inspection work easier when facilities use licensed haulers.
Don't use a hauler who can't produce a current ADH permit. Grease waste dumped illegally in Arkansas can trigger civil penalties under the Arkansas Water and Air Pollution Control Act, and a hauler who cuts corners on disposal is not one you want your business name attached to [9].
For more on how the paper trail works in practice, the EPA's National Pretreatment Program explains how state and local programs interact with federal requirements [7].
What can go wrong and what does it cost you?
Grease trap violations in Arkansas are not theoretical. The consequences are real, and they're worth knowing before you skip a pump-out or let your manifests lapse.
A local pretreatment permit violation, like blowing past the allowable fats, oils, and grease (FOG) discharge limit in your sewer connection permit, can bring a notice of violation from your local POTW. Most first-time notices come with a compliance schedule rather than immediate fines, but repeat violations escalate. Local POTWs in Arkansas can assess administrative penalties under their own ordinances, and those can reach hundreds of dollars per day for continuing violations.
If your trap backs up into the sanitary sewer and causes a spill or blockage, the city may bill you for cleaning the sewer line. Those invoices can run $500 to $3,000 or more depending on the severity and location of the blockage.
An illegal discharge that reaches a waterway can trigger enforcement under the Arkansas Water and Air Pollution Control Act, with civil penalties of up to $10,000 per day per violation [9]. That's not the common outcome for routine grease neglect, but it's the ceiling you're operating under.
The math is simple. A $350 pump-out every 90 days costs you $1,400 a year. A single enforcement action costs more than that before you hire a lawyer.
Frequently asked questions
How much does a grease trap cost in Arkansas?
A new grease interceptor installation in Arkansas runs $1,500 to $8,500 or more depending on size, type (above-ground hydromechanical vs. in-ground concrete), and local labor costs. Routine pump-out service from a licensed liquid waste transporter typically costs $250 to $600 per visit. Get at least three itemized quotes from licensed plumbing contractors before committing to a price.
Do you need a license for grease trap work in Arkansas?
Yes, three licenses are in play. The hauler who pumps and transports grease waste needs an ADH Liquid Waste Transporter permit. The plumber installing the interceptor needs a license from the Arkansas State Board of Plumbing Examiners. Your facility likely needs a local pretreatment or wastewater discharge permit from your city or county's POTW. Confirm all three before you open.
How long does grease trap permitting take in Arkansas?
For a local pretreatment permit, budget 4 to 12 weeks from a complete application to approval, depending on the jurisdiction's workload and whether plan review is required. A building department plumbing permit for the installation typically takes 5 to 15 business days. Confirm current timelines directly with your local POTW and building department before scheduling construction.
How often does a grease trap need to be pumped in Arkansas?
The IPC standard used in Arkansas recommends pumping when the trap is 25% full of grease and solids. For most full-service restaurants, that means every 30 to 90 days. Your local pretreatment permit may set a minimum frequency. Check your permit conditions and stick to them. Missing a scheduled pump-out is the most common reason facilities receive a notice of violation.
Who regulates grease trap haulers in Arkansas?
The Arkansas Department of Health issues Liquid Waste Transporter permits to companies that pump and haul grease trap waste under Arkansas Code Annotated Title 14, Chapter 236. Contact the ADH Division of Environmental Health Services to verify a hauler's current permit status. Hiring an unpermitted hauler creates liability for your facility if the waste is disposed of improperly.
What records do I need to keep for my grease trap in Arkansas?
Federal pretreatment rules (40 CFR Part 403) require facilities with a pretreatment permit to keep grease trap service records for at least three years. Those records include service dates, volumes removed, hauler name and permit number, and the disposal facility used. Your local POTW may require you to submit these records periodically. Keep every manifest your hauler provides.
Does Arkansas have a statewide grease trap ordinance?
No. Arkansas does not have a single statewide grease trap ordinance. The state sets the plumbing code framework (International Plumbing Code) and the hauler licensing rules (ADH), but specific grease trap requirements for food service facilities are set by local municipalities and their pretreatment programs. Requirements vary significantly from city to city.
What size grease trap do I need in Arkansas?
Sizing comes from the International Plumbing Code, which Arkansas adopted statewide, and from your local POTW's pretreatment requirements. Hydromechanical units are sized by flow rate in gallons per minute; gravity interceptors are sized by liquid capacity. Your local building department or POTW pretreatment coordinator will specify the minimum size for your facility type and fixture load.
Can a food truck in Arkansas skip having a grease trap?
Generally yes, if the food truck operates from a permitted commissary that has its own grease interceptor. The commissary handles grease waste disposal on behalf of the mobile unit. You need a written commissary agreement documenting this. If your truck operates semi-permanently at a fixed site, your local POTW may require a separate facility permit. Confirm with the ADH and your local pretreatment authority.
What happens if I don't maintain my grease trap in Arkansas?
Neglecting your grease trap can bring a notice of violation from your local POTW, city charges for sewer line cleaning if a blockage occurs (often $500 to $3,000), and escalating administrative penalties for repeat violations. Severe cases involving illegal discharge into waterways can trigger civil penalties up to $10,000 per day under the Arkansas Water and Air Pollution Control Act.
Is there a state inspection of grease traps in Arkansas?
State-level grease trap inspections typically happen through your local POTW's pretreatment inspection program, not through a separate state agency. The Arkansas Division of Environmental Quality oversees the pretreatment program statewide, but the actual facility inspections are conducted by local pretreatment coordinators at the city or county level. Frequency varies by jurisdiction and permit class.
How do I find out if my Arkansas city has a pretreatment program?
Contact your city's wastewater utility or public works department and ask if they have an industrial pretreatment program. You can also check with the Arkansas Division of Environmental Quality, which keeps records of permitted POTWs and their approved pretreatment programs. If your city doesn't have a pretreatment program, your county or a regional authority may have jurisdiction.
What is a liquid waste transporter permit in Arkansas?
It's a state permit issued by the Arkansas Department of Health that authorizes a company to pump, transport, and dispose of septage and grease trap waste. The permit is required under Arkansas Code Annotated Title 14, Chapter 236. Haulers must renew it annually. As a facility owner, ask for your hauler's permit number and verify it's current before every service contract.
Is grease trap installation cheaper in Arkansas than in other states?
Generally yes. Arkansas plumbing labor costs run below the national median, which lowers installation quotes compared to most coastal and Midwest states. A mid-range interceptor installation in Arkansas runs $3,000 to $6,000, compared to $4,500 to $9,000 in Florida or $5,000 to $10,000 in Illinois. Disposal costs for pump-outs also tend to be lower due to less constrained disposal infrastructure in the region.
