Insurance for Grease Trap
& FOG Contractors.
Grease work looks like septic work and is regulated as something else entirely. That gap is where the exposure lives, and it is the part most policies were never written to contemplate.
We shop your septic business with carriers like
What a grease operation needs covered
The policy names are familiar. What differs is whether your application actually describes grease work.
Pollution liability that names the operation
If your policy was written for septic pumping and you later added grease routes, the operations described may no longer match what you do. See pollution liability.
Commercial auto covering the load you actually haul
The standard form excludes a spill of the material being transported. See commercial auto.
Equipment coverage for pumps and hoses on grease duty
Grease service is hard on equipment, and the gear lives on the truck. See equipment and inland marine.
Workers compensation reflecting restaurant-side work
Alley access, hot grease and confined service areas behind commercial kitchens are not residential-lawn hazards. See workers compensation.
The Septic Cleaning Insurance Group Policy Review
We read the whole policy
Before we quote anything we read what you already have, cover to cover, and tell you plainly what it does and does not do.
We map your actual operation
Pumping, installation, hauling, grease trap, portable units: each one underwrites differently. We classify what you really do, not a generic contractor code.
We shop carriers who understand septic risk
Standard markets when they fit, specialty and E&S markets when they do not. If a carrier does not understand pollution exposure, we do not use them.
We explain the quote in plain language
You get the number, the limits, the exclusions that matter, and the reasoning. No pass-through, no blind binding.
What we ask a grease hauler
Whether grease and septage share a tank
The single highest-value question on a grease account, and one most owners have never been asked.
Which municipalities you work in
Because the enforceable rule is local, and the obligations differ across the line.
Whether your service records would stand up
Ordinances commonly require a cleaning report after every pump out. Those records are your defence if an overflow is traced back.
Whether your policy application mentions grease at all
Adding a service line without telling anyone is how an otherwise good account finds out it was underwritten for something else.
Grease trap waste is not septage, and the law says so explicitly
If you run grease and septic routes out of the same yard, this is the paragraph to read twice.
Two different legal categories, one tank
Federal rules define domestic septage as material from a treatment works “that receives only domestic sewage,” and EPA’s plain-language guide states the definition “excludes grease-trap pumpings and commercial or industrial waste.” EPA guidance goes further: the rule “does not apply if domestic septage is mixed with either commercial septage (e.g., grease from a grease trap at a restaurant) or industrial septage prior to use or disposal.”
Co-mingling is not a small compliance slip
It reclassifies the whole load. A tank of domestic septage that was lawfully land-appliable stops being domestic septage the moment commercial grease goes in, and the material then falls under a different federal part with different requirements.
Which means your disposal route changes mid-shift
The destination that was lawful for the septage portion is no longer lawful for the mixed load. That is a decision made by a driver with a schedule, not by a compliance officer with a manual.
The practical answers are operational, not clerical
Separate tanks, separate trucks, or a disposal arrangement that does not depend on domestic septage status. Choosing one of those deliberately is cheaper than discovering the problem during an inspection.
And it is a question almost no agent asks
We ask it on every account that mentions grease work, because the answer changes both the regulatory picture and which carriers will write the risk.

Because it is what blocks the sewer
Fats, oils and grease are a named cause of sanitary sewer overflows, which is why municipalities regulate the traps and the haulers rather than leaving it to the restaurants.
EPA names FOG among the causes of overflows
In its guidance on sanitary sewer overflows, EPA lists “inappropriate materials sent to the sewers – materials such as fats, oils and grease (FOG), and some household products” among the problems that cause them, and notes that overflows “occasionally occur in almost every sewer system.”
The enforceable rule is local, not federal
Federal pretreatment regulation provides the structure and reaches non-domestic sources discharging into treatment works, but it contains no grease trap mandate. The rule your customer and you actually have to obey is a municipal or utility ordinance, and it differs by jurisdiction.
Which means your compliance picture is a patchwork
A hauler working across several municipalities is working under several different ordinances with different frequencies, different reporting and different record requirements. That variation is itself part of the risk.
The 25 percent rule is the common standard
Portland, Oregon states that “most interceptors need to be cleaned when they become 25 percent full of FOG and solids,” and that “a business must file a cleaning report with the City after every interceptor cleaning or pump out.” Variants of that threshold appear in ordinances across the country, often with a maximum interval attached.

Criminal enforcement in this trade runs at the hauler, not the restaurant
- In Alabama, a grand jury indicted a waste disposal company, its president and its top manager over “offenses involving the illegal disposal of waste into the sewage treatment systems of Mobile and of neighboring municipalities”, with guilty pleas entered for dumping from pump trucks into area sewers
- In Tennessee, a Dickson-based grease hauling company and its president pleaded guilty to Clean Water Act violations for illegal disposal of waste grease into municipal sewers
- Both are criminal Clean Water Act matters
- Both named the company and its principals, not the food service establishments that generated the waste
- Criminal fines and penalties are not insurable under any policy
- Deliberate acts are excluded from general liability and from pollution liability alike
- What insurance addresses is the accidental release and the third-party claim that follows it
- What it cannot address is an enforcement outcome, a debarment, or a lost municipal permit

Underwriters who’ve actually walked a septic job site
Septic Cleaning Insurance Group
We built this agency around one gap we kept seeing: big-box commercial insurers write septic contractor policies the same way they write policies for any other trade, missing the environmental and pollution exposure that actually matters in this business. Our team goes deep on septic-specific risk before recommending coverage, maintains relationships with carriers who understand pumping, installation, and disposal operations specifically, and keeps specialty and E&S markets in reserve for the accounts standard carriers will not touch.
Straight answers, no insurance-speak
Physically yes, legally it changes everything. Federal rules define domestic septage as coming from a works receiving only domestic sewage, and EPA’s guide states the definition excludes grease trap pumpings. EPA guidance adds that the rule does not apply once domestic septage is mixed with commercial septage such as restaurant grease. The mixed load loses its domestic septage status and falls under different requirements.
The workable answers are operational: separate tanks, separate trucks, or a disposal arrangement that does not rely on domestic septage status for any of it. Which one makes sense depends on your volumes and what receiving capacity exists near your routes. It is worth deciding deliberately rather than by whichever stop came last.
Not directly. Federal pretreatment regulation sets the structure and reaches non-domestic sources discharging into treatment works, but it carries no grease trap standard. The rule that binds you is the local ordinance where the restaurant sits, which is why a hauler working several municipalities is working under several different rulebooks.
It depends on the ordinance, and the common standard is proportional rather than calendar-based. Portland, Oregon’s guidance is that most interceptors need cleaning at 25 percent full of FOG and solids, with a cleaning report filed after every pump out. Many ordinances pair that threshold with a maximum interval.
Because it is a named cause of sanitary sewer overflows. EPA lists fats, oils and grease among the inappropriate materials that cause them. An overflow is a public health and permit event for the municipality, which is why they regulate the traps and the haulers rather than trusting the kitchen.
It can be, and the enforcement record suggests regulators look at the hauler. In documented Clean Water Act prosecutions in Alabama and Tennessee it was the hauling company and its principals who were charged, not the food service establishments. Service records showing when you pumped and what you found are a real defence.
It should, but the operations described on your application have to include it. If your policy was written for a septic pumping operation and you have since added grease routes, that is a disclosure gap worth closing before a claim rather than after. See pollution liability.
It can, because classification follows the operation performed. It also changes your practical exposure: hot grease handling, restaurant alley access, and work in confined service areas behind commercial kitchens are not the same hazards as a residential tank in a lawn.
