General Liability Insurance
for Septic Contractors.
The base layer of every septic contractor program, what it actually pays for, and the two things it will never cover: your own work, and the waste you handle.
We shop your septic business with carriers like
What the policy actually contains
Three coverage parts, each with its own job. Limits are set on your declarations page rather than by the form itself.
Coverage A, bodily injury and property damage
The core. Pays what you become legally obligated to pay as damages because of third-party injury or property damage caused by an occurrence, defined as an accident including continuous or repeated exposure to substantially the same general harmful conditions.
Coverage B, personal and advertising injury
A different set of offences entirely: false arrest, malicious prosecution, wrongful eviction or entry, defamation. Rarely the reason a septic contractor buys the policy, occasionally the reason it pays.
Coverage C, medical payments
Pays medical expenses for an accident on your premises or because of your operations, regardless of fault, if expenses are incurred and reported within a year. Note it does not apply to anything inside the completed operations hazard, so a homeowner hurt during the dig can draw on it and one hurt by the finished system cannot.
Two separate aggregates
A General Aggregate and a parallel Products-Completed Operations Aggregate. Work that is finished draws on its own tower rather than eating into the general one.
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 a specialist actually checks on this policy
Whether the additional insured endorsements exist
Not whether the certificate says so. We look for the actual CG 20 10 and CG 20 37 forms attached to the policy, because contracts are enforced against endorsements rather than certificates.
Whether the subcontractor exception is intact
Some carriers amend or remove it. For an installer who subs out tank setting or field work, that amendment is the difference between a covered claim and a self-funded rebuild.
How the pollution exclusion is worded on your form
The base exclusion and the total pollution exclusion endorsement behave very differently, and you cannot tell which you have from the declarations page.
Whether your completed operations aggregate is adequate
Septic claims surface years after the work. The limit that matters is often the one on the tail, not the one on current operations.
Your general liability policy does not pay to redo your own work
This surprises more septic installers than any other feature of the policy, and it is not a loophole. It is written plainly into the form.
Exclusion l. Damage To Your Work
ISO form CG 00 01 04 13 excludes “‘property damage’ to ‘your work’ arising out of it or any part of it and included in the ‘products-completed operations hazard’.” In plain terms: if the system you installed fails, the cost to tear it out and install it again is yours. That is a business risk, not an insurable one.
What IS covered is the damage to everything else
The distinction that matters: your work is excluded, but third-party property damage caused by the failure is not. Sewage backing up into a finished basement, effluent surfacing and reaching a neighbour’s well or a stream, landscaping destroyed when the drainfield fails. Those are covered occurrences. The tank and the field you installed are not.
The subcontractor exception is the most valuable sentence in the form
Exclusion l. ends with: “This exclusion does not apply if the damaged work or the work out of which the damage arises was performed on your behalf by a subcontractor.” If a sub set the tank or laid the field and got it wrong, the exclusion falls away. If you self-perform everything, it does not. For an installer deciding whether to sub out work, this is a genuine coverage consequence.
During the job, a different exclusion bites
Exclusion j. removes “that particular part of real property on which you or any contractors or subcontractors working directly or indirectly on your behalf are performing operations, if the ‘property damage’ arises out of those operations.” Crack a buried water line while trenching a leach field and the part you were working on is excluded, though damage elsewhere on the property is not.
You cannot be tendered a pure economic loss either
Exclusion m. removes damage to “impaired property or property that has not been physically injured” arising from a defect in your work. A homeowner cannot claim loss of use of an undamaged house simply because the system is defective.

First flush is the moment the policy changes shape
Septic claims rarely happen on the day of the install. They happen months or years later, which puts them in a different part of the policy with its own separate limit.
The trigger is use, not sign-off
The form deems your work completed at the earliest of several points, including “when that part of the work done at a job site has been put to its intended use.” The homeowner flushes the toilet and that portion of the work is complete, whether or not you have finished grading, returned for punch-list items, or been paid.
Outstanding warranty work does not keep it open
The form is explicit: “Work that may need service, maintenance, correction, repair or replacement, but which is otherwise complete, will be treated as completed.” Going back to fix something does not move the claim out of completed operations.
Your warranties count as your work
The definition of “your work’” includes “warranties or representations made at any time with respect to the fitness, quality, durability, performance or use” of it. What you promised the homeowner about the system is swept into the same exclusion as the work itself.
You effectively carry two separate towers of coverage
The Products-Completed Operations Aggregate is a parallel limit, not a slice of the General Aggregate. The form says the General Aggregate applies to damages “except damages because of ‘bodily injury’ or ‘property damage’ included in the ‘products-completed operations hazard’.” Exhausting one does not exhaust the other.

The certificate your GC asked for does not actually give them anything
If you work for general contractors, developers or municipalities, this is where contracts quietly go wrong.
- CG 20 10 adds the GC as an additional insured for liability caused by your acts or omissions “in the performance of your ongoing operations”
- CG 20 37 adds them for liability caused by your work “included in the ‘products-completed operations hazard’”, which is the completed-operations tail
- Both 04 13 editions limit the grant to no broader than the contract requires, and to the lesser of the required or available limits
- For septic work specifically you usually need both, because the claims arrive after completion
- A certificate of insurance confers nothing. The ACORD 25 form says so itself: it “IS ISSUED AS A MATTER OF INFORMATION ONLY AND CONFERS NO RIGHTS UPON THE CERTIFICATE HOLDER”
- The same form states it “DOES NOT AFFIRMATIVELY OR NEGATIVELY AMEND, EXTEND OR ALTER THE COVERAGE AFFORDED BY THE POLICIES”
- And directly on this point: “If the certificate holder is an ADDITIONAL INSURED, the policy(ies) must be endorsed… A statement on this certificate does not confer rights to the certificate holder in lieu of such endorsement(s)”
- CG 20 10 on its own switches off once your work is put to its intended use, which is exactly when septic claims start
If a contract requires additional insured status and all that was issued is a certificate listing it, nobody is actually an additional insured. We check the endorsements on your policy rather than the box on the certificate.

Which states make you carry it to hold a licence
Fewer than people assume, and the amounts are not uniform. We list only what we confirmed against the actual rule. Where a state is missing, we did not verify it and would rather say that than print a number you might rely on.
- Ohio requires “proof of no less than five hundred thousand dollars general liability insurance coverage,” applying across installer, septage hauler and service provider registrations
- Minnesota requires a minimum of $100,000 of general liability to hold an SSTS licence, alongside a $25,000 corporate surety bond
- Utah requires public liability insurance, with the amount set by administrative rule rather than stated in the statute
- Indiana, Iowa and Missouri impose no state-level general liability requirement on septic contractors
- Georgia is widely misreported. The $1,000,000 liability certificate attaches to the soil classifier, engineer or geologist submitting a soil evaluation, not to the installer or pumper, and septic permitting runs through County Boards of Health
- Several states delegate requirements to counties, so the number that governs you may be local rather than statewide
- Meeting a state minimum is a licensing fact, not a coverage opinion. $500,000 of general liability still excludes the septage you handle
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
No. Exclusion l. of the standard form removes property damage to your own work once it is in the completed operations hazard. The cost to tear out and redo the system is yours. What the policy does cover is the damage the failure causes to other property, such as sewage in a finished basement or effluent reaching a neighbour’s well.
Then the exclusion generally does not apply. The form says the your-work exclusion does not apply if the damaged work, or the work the damage arose out of, was performed on your behalf by a subcontractor. It is one of the few places where subbing work out improves your coverage position rather than complicating it.
Almost certainly not. The same form excludes pollutants transported, handled, stored, treated or disposed of as waste, and defines waste as a pollutant. That is a separate conversation and a separate policy. See our page on pollution liability.
Not if the contract requires additional insured status. The ACORD certificate states on its face that it confers no rights on the certificate holder, and that if the holder is an additional insured the policy must actually be endorsed. A certificate naming someone as additional insured, without the endorsement, gives them nothing.
Because CG 20 10 covers ongoing operations and stops once your work is put to its intended use. For septic work, that is the moment before most claims happen. CG 20 37 extends the status into completed operations, which is where the real exposure lives.
No, defense is paid in addition to the limit under the standard form. But it is not unlimited: the insurer’s duty to defend ends when the applicable limit has been used up paying judgments or settlements. Big claims can exhaust the limit and end the defense with the matter still open.
Courts have gone both ways on this and several legislatures have stepped in. The trend among state supreme courts since 2012 has been toward treating construction defects as occurrences. What does not change in any state is that the cost to redo your own defective work stays excluded. We would not tell you how your specific state’s courts will rule.
The form itself does not set dollar amounts; limits live in your declarations page. The figures that matter in practice are the ones your contracts and your state licensing require, and the size of the job you are bidding. We work backwards from those rather than quoting a default.
