Septic Contractor Insurance in Illinois

Illinois issues a real state septic installer license after a written examination — and the approval for an individual system is a second step that may be filed at a local counter instead.

An orange sewer pipe laid in an open trench below a cut lawn edge — septic contractor insurance in Illinois

Illinois licenses this trade itself. The Illinois Department of Public Health issues a statewide license for the installing contractor, under the Private Sewage Disposal Licensing Act, on a passed written examination — and the Act writes the duty onto the person doing the work rather than leaving it to guidance. 225 ILCS 225/4(a): “Any person who constructs, installs, repairs, modifies, or maintains a private sewage disposal system, other than a system which serves his own single family residence, shall be licensed by the Department as a Private Sewage System Installation Contractor”. That is the credential, and it is the whole of what the credential is. It is not the approval for the particular system you are about to put in the ground. 77 Ill. Adm. Code 905.190(a) calls for plan approval before construction begins “from the Department or local authority”, on forms provided by “the Department or local authority”, and 225 ILCS 225/9 is the provision that creates that second counter: the Department “may designate and use full-time municipal, district, county or multiple county health departments as its agents”. So the license is the state’s, and the approval for the job in front of you may be a local health department’s. Given only one of those two, a contractor plans the work around the wrong counter.

Read the statute’s sentence for what it actually does, because that is where the force of the license lives. The Act says the person doing the work “shall be licensed by the Department”, and the private sewage code then requires the licensed contractor to be present at the site while the work is done. Under 77 Ill. Adm. Code 905.20(r) the licensed installation contractor has to be present at the site while the construction, installation, repair, modification or maintenance is done, and 905.20(s) lets an unlicensed individual dig only under his direct supervision. The license is held by a person, and the person has to be there, so one licensed contractor cannot be present on a second crew’s job at the same time. For an owner running more than one truck that is the operative fact about the whole licensing scheme, and it is the one that shows up in a scheduling argument long before it shows up in a claim.

The duty is scoped twice — by a class of person in the Act, and by a local option that can displace the state license. The first is a class of person, and the Act draws that boundary itself in the same subsection: “A person who owns and occupies a single family dwelling and who constructs, installs, maintains, services or cleans the private sewage disposal system which serves his single family residence shall not be required to be licensed under this Act, however, such person shall comply with all other provisions of this Act and the private sewage disposal code promulgated hereunder by the Department.” Every clause of that is doing work. It is the owner, occupying, of a single family dwelling, on the system that serves his own residence — and even then only the licensing requirement falls away, because the sentence keeps him inside every other provision of the Act and the code. A landlord is not within it. Neither is a builder, a flipper, or a friend with a backhoe. The carve-out is narrow, and it does not reach the operator who works on a system other than his own residence, which is the operator this page is written for.

The second limb is not about a person at all. It is about a place, and it is the one provision that could change the answer for a particular jurisdiction. 225 ILCS 225/10(a) preserves a unit of local government’s ordinance for the regulation and inspection of private sewage disposal contractors “provided such ordinance establishes a system at least equal to state regulation and inspection”, and then says what follows from that approval: “If such plan is approved by the Department the ordinance shall prevail in lieu of the state licensure, fee and inspection program”. That is a real route by which the state licensing program can be displaced inside one jurisdiction’s boundaries. Two sentences this page will not write about it. It will not say that the license is displaced somewhere, because no approved local program was found and a named one would be an inference wearing the clothes of a finding. And it will not say the state license runs everywhere untouched, because an ordinance approved by the Department shall prevail in lieu of the state licensure program. Ask the local authority for your job whether it runs an approved program of its own. That is a question with an answer, and it costs a phone call rather than a rebuild.

The local counter also sets the timing: plan approval before construction begins, and notice to the Department or local authority before work starts. 77 Ill. Adm. Code 905.190(a) puts the plan approval before construction begins; 905.190(d) puts notice to the Department or local authority at least 48 hours before work starts; and where the work went ahead without either, 905.190(e) obliges the owner or the installation contractor to uncover any portion already backfilled. Read that last one twice. That uncover-and-re-expose obligation is rework triggered by paperwork rather than by workmanship, and the system may have been perfectly built. Local agencies in Illinois review private sewage plans either under an ordinance of their own or as the Department’s designated agent, so the question of who approves a given job is a question about that jurisdiction and never a question about the state.

Pumping and hauling is a second state license rather than an endorsement on the first, and the fact that one agency issues both is the easiest thing here to get wrong. 225 ILCS 225/4(a) creates it in the same subsection as the installer duty: “any person who cleans or pumps waste from a private sewage disposal system, other than a system which serves his own single family residence, or hauls or disposes of wastes removed therefrom shall be licensed by the Department as a Private Sewage Disposal System Pumping Contractor”. The rule states it again from the operating side — “Cleaning, pumping, disposing and hauling of waste from a private sewage disposal system shall be done by a licensed Private Sewage Disposal System Pumping Contractor.” — and 77 Ill. Adm. Code 905.180(b)(3) has the person who wants both pass both examinations. An outfit that installs and pumps is therefore carrying two credentials, two renewal clocks and two ways to be suspended on one operation. A third class sits beside them and its verbs are broader than pumping: 905.135(a) reaches “Any person operating in Illinois who sells, rents, leases, transports, services, cleans, sanitizes or maintains a portable toilet or portable potable hand washing unit or pumps, transports or disposes of waste from portable toilets or portable potable hand washing units”, which brings a pure rental operation inside a portable sanitation license before anyone has pumped anything — and under 225 ILCS 225/5b(a-5) each technician who services those units holds a certificate of his own. What the pumping license carries afterwards is a set of continuing operating conditions: 905.170(b) has the business name, the town of company origin and the telephone number painted on each side of every pumper truck in letters at least 8 inches high in contrasting colors; 905.170(d) sets the tank, pump and discharge-nozzle condition of the collection vehicle; 905.170(e) has the contractor notify the Department and the local authority annually of the disposal sites used, identified by county, township, range and section and by the owner’s name and address; and 905.170(a) runs the whole of it in accordance with that Section and with 40 CFR 503. Those conditions attach to each pumper truck and to each disposal site, not to a single job.

There is no Illinois septic inspector certification to hold. That absence is the finding on this page most easily read backwards, so it is worth being exact about what it does and does not mean: the state regulates the evaluation rather than the evaluator, and the evaluation is compulsory. 77 Ill. Adm. Code 905.20(q)(3)(A)(i) fixes who is allowed to carry one out on a residential septic tank, and the list it gives is closed — “The system may be evaluated by the homeowner, a Private Sewage Disposal System Installation Contractor, a licensed Environmental Health Practitioner, an Illinois licensed Professional Engineer, a representative of the Department, or an agent of the Department or local health department.” Strike the homeowner and the two public routes off that list and what is left is credentialed work — the installation contractor, the environmental health practitioner and the professional engineer each already hold an Illinois license. (A)(ii) repeats the list for non-residential property with the homeowner struck out of it. The cycle is in the rule as well. A residential septic tank is evaluated before or within 3 years of installation and at minimum every 5 years after the first; a non-residential system within 3 years of installation and at minimum every 3 years after; an aerobic treatment unit at least once every 6 months under (q)(3)(B); and sand filters and waste stabilization ponds with surface discharges at minimum once a year under (q)(3)(C). What the evaluation measures is stated too — whether scum and settled solids exceed 33% of the tank’s liquid capacity, above which the tank is pumped out and maintenance performed. And 905.20(q)(4) closes the loop: failing to operate, maintain and service the system is itself a violation of the Act and the code. So the duty is real, it is continuous, and it sits on the system and on the credential-holder who evaluates it rather than on an inspector license this state never created. For a contractor that cuts both ways — his own installer license is what qualifies him to perform a statutory evaluation on somebody else’s system, which is recurring service work and a professional exposure at the same time.

Workers compensation is the Illinois answer that depends on none of the above, and it applies automatically, without election, to every employer in an extra hazardous enterprise. 820 ILCS 305/3 opens by having the Act “shall apply automatically and without election to the State, county, city, town, township” and onward, and it then sets out the trades it treats as extra hazardous. Second on that list: “Construction, excavating or electrical work.” A septic crew falls inside the Act because of the work it does, not anything its employer files, and construction and excavating carry no threshold at all. Illinois does carry a payroll threshold, but it sits at item 17(a) of that same list, for businesses selling goods or rendering services to the public at large: true about a shop, and not about this trade. Having the liability, an employer has to secure it, and 820 ILCS 305/4(a) sets out four routes — approval as a self-insurer at (a)(1); security, indemnity or bond where the Commission is not satisfied of financial ability at (a)(2); insurance at (a)(3); or some other provision satisfactory to the Commission at (a)(4). Not one of them is a state fund, because Illinois runs no such fund. The ordinary route reads: “Insure his entire liability to pay such compensation in some insurance carrier authorized, licensed, or permitted to do such insurance business in this State.” The same paragraph has the policy cover all of the employees and the entire compensation liability, admits two or more insurers only where the entire liability of the employees working at or from one location sits with one of them or is self-insured, and voids outright any provision that would limit or modify that liability. One further Illinois rule is worth a construction page and is not in the obvious place: under 820 ILCS 305/4(a-1) an employer engaged primarily in the building and construction industry, to which (a)(3) applies or which is in a group self-insurance plan, makes its payments based upon the premium rates of the situs where the work or project is located in Illinois, regardless of its state of domicile or principal place of business. Whether a given septic business is engaged primarily in that industry is a factual question about that business, and this page decides it for nobody.

The exceptions Illinois does run reach the owner personally and never the crew. 820 ILCS 305/3(20) provides that “Nothing contained in this Act shall be construed to apply to any sole proprietor or partner or member of a limited liability company who elects not to provide and pay compensation” for accidental injuries sustained by himself, and 305/3(17)(b) lets a bona fide President, Vice President, Secretary or Treasurer of a corporation withdraw himself as an individual, effective when the insurance carrier receives written notice, and elect back in the same way. Both are self-exclusions by a principal. Neither takes an employee out of the Act, and neither makes coverage optional for a firm that employs anybody. What failure looks like is set out at 820 ILCS 305/4(d): a Commissioner who determines after a hearing that an employer knowingly failed to provide coverage may treat that failure as an immediate serious danger to public health, safety and welfare, and a work-stop order may be issued and posted at the employer’s places of employment and job sites, with law enforcement available to keep employees off the site until proof of insurance lifts it. A knowing failure is a Class 4 felony and a negligent one a Class A misdemeanor, and each day’s violation is a separate offense.

One last pair of Illinois findings explains why the license and the compensation duty never meet. The Private Sewage Disposal Licensing Act attaches no insurance condition and no bond to this license — a read finding rather than an absence of notice, because the researcher swept all twenty-five published sections of the Act and seven sections of the private sewage code for insurance, bond, liability and surety terms and found two hits, neither of them a financial-responsibility condition. The denominator belongs with the finding: those seven sections are not the whole of the code, so what can honestly be said is that the state installer license carries no proof-of-coverage condition, and not that no Illinois requirement anywhere reaches a contractor’s insurance. That negative then does a second job. 820 ILCS 305/4(a-3) imposes a penalty on a business “engaged in activities requiring licensure by a State agency, for which proof that it has insured its workers’ compensation liability is a requirement for licensure” which fails a requirement of subsection (a) — and read quickly, that looks written for a state-licensed septic contractor. It is not. The provision engages only where the licensing statute itself demands proof of coverage, and this one demands nothing of the kind. So the compensation duty here comes from the nature of the work and not from the license: letting the coverage go does not cost the license, and holding the license buys nothing on the compensation side. The sections below set out each authority with a link to it, so you can check all of this rather than take our word for it.

What Illinois requires of a septic business

Installing

Illinois issues a real STATE septic installer license. The Illinois Department of Public Health licenses the Private Sewage Disposal System Installation Contractor under the Private Sewage Disposal Licensing Act, statewide, after a written examination — there is no county registration step in the credential itself.

Authority 225 ILCS 225/4(a); 225 ILCS 225/5(a); 225 ILCS 225/3(8); 225 ILCS 225/8(a)(7); 225 ILCS 225/10(a); 77 Ill. Adm. Code 905.20(r); 77 Ill. Adm. Code 905.20(s); 77 Ill. Adm. Code 905.180(b)(1); 77 Ill. Adm. Code 905.190(a); 77 Ill. Adm. Code 905.200(a) — read the source

Pumping and hauling

Illinois’s septage credential is a STATE LICENSE from the same agency and the same Act as the installer license — but it is a DIFFERENT CLASS with its OWN examination, and a third class sits beside it for portable sanitation. The environmental agency does not issue any of them.

Authority 225 ILCS 225/3(11); 225 ILCS 225/4(a); 225 ILCS 225/4(c); 225 ILCS 225/5(a); 225 ILCS 225/5b; 225 ILCS 225/5b(a-5); 77 Ill. Adm. Code 905.20(r); 77 Ill. Adm. Code 905.135(a); 77 Ill. Adm. Code 905.135(b); 77 Ill. Adm. Code 905.170(a); 77 Ill. Adm. Code 905.170(b); 77 Ill. Adm. Code 905.170(e); 77 Ill. Adm. Code 905.170(f); 77 Ill. Adm. Code 905.180(b)(2); 77 Ill. Adm. Code 905.200(a) — read the source

Inspecting and evaluating

Illinois has no septic inspector certification. The state instead names, in the private sewage code itself, which credential-holders may evaluate a system — and for a commercial evaluation the qualifying credential is the INSTALLER LICENSE, a licensed environmental health practitioner, a licensed professional engineer, or the health department itself.

Illinois certifies nobody as a septic inspector, but it does not leave the evaluation unregulated: 77 Ill. Adm. Code 905.20(q)(3) makes the evaluation MANDATORY on a stated clock and names, as a closed list, who may perform it — and every commercial route on that list is a person who already holds another Illinois credential. WHAT ILLINOIS REGULATES INSTEAD OF AN INSPECTOR IS THE INSPECTION: who may do it, when it must happen, and what it must measure.

Authority 77 Ill. Adm. Code 905.20(q)(3)(A)(i); 77 Ill. Adm. Code 905.20(q)(3)(A)(ii); 77 Ill. Adm. Code 905.20(q)(3)(B); 77 Ill. Adm. Code 905.20(q)(3)(C); 77 Ill. Adm. Code 905.20(q)(4); 225 ILCS 225/8(a)(1); 225 ILCS 225/9; 225 ILCS 225/10(a); 225 ILCS 37; 225 ILCS 325 — read the source

Workers compensation

Illinois workers compensation applies AUTOMATICALLY AND WITHOUT ELECTION to every employer and every employee engaged in any department of the enterprises the statute declares extra hazardous, and the second thing on that list is "Construction, excavating or electrical work" — so an Illinois septic installer’s employees are inside the Act by the nature of the work, with no threshold to cross and no election to make, and the employer must then secure that liability by one of the four routes in 820 ILCS 305/4(a).

Authority 820 ILCS 305/3; 820 ILCS 305/3(17)(a); 820 ILCS 305/3(17)(b); 820 ILCS 305/3(19); 820 ILCS 305/3(20); 820 ILCS 305/4(a); 820 ILCS 305/4(a)(1); 820 ILCS 305/4(a)(2); 820 ILCS 305/4(a)(3); 820 ILCS 305/4(a)(4); 820 ILCS 305/4(a-1); 820 ILCS 305/4(a-3); 820 ILCS 305/4(b); 820 ILCS 305/4(d); 820 ILCS 305/4a(1) — read the source

What Illinois requires of a septic business — installing, hauling, inspecting and workers’ comp from private insurers — and what each requirement leaves to the insurance program.

A panel for Illinois in rows. Each row sets one thing the state requires beside the exposure that requirement leaves open and the coverage line that answers it. Installing: The state issues a septic installer license. It leaves open a failed install or drainfield, damage to the customer’s property, which General Liability and Pollution Liability answer. Pumping and hauling: A septage hauling permit is on the books. It leaves open a spill or release in transit, the truck at fault, which Commercial Auto and Pollution Liability answer. Inspecting and evaluating: No statewide inspector or evaluator certification; it varies locally. It leaves open a missed defect in an inspection or design, which Professional Liability answers. Workers compensation: Compulsory for covered employers; private insurers write it. It leaves open an injured employee in the trench or on the truck, which Workers Compensation answers. Notes: A license, permit or bond is not a policy — a bond secures the public body that requires it, not the customer. The conclusion reads: The credential is not the coverage — the program is. No figures are shown.

Where we write in Illinois

Chicago · Cook County

Work sited at the sewer boundary is work on lots that were passed over by a district once and may be reached by one later, which puts a contractor’s completed systems on ground whose regulatory status can change under them — and it means the same crew’s week mixes systems governed by the private sewage code with connections governed by somebody else’s permit.

Joliet · Will County

An uncover-and-re-expose obligation is a rework cost that lands on the contractor and is triggered by paperwork rather than by workmanship — the rarest kind of loss to reserve for and the easiest to argue about, because the system may be perfectly built.

Rockford · Winnebago County

A contractor who land-applies is operating on land he does not own, named in a filing he made himself, with a setback measured from water features — which is a pollution and third-party-property exposure sitting on a document trail the operator created, and it is separable from anything that happens at the customer’s tank.

Peoria · Peoria County

Weather-and-terrain conditions on a disposal route mean a pumping contractor’s lawful capacity moves week to week, and a full truck with nowhere lawful to empty it is an operational exposure that turns into a compliance exposure quickly.

Springfield · Sangamon County

A single central licensing counter means one renewal clock, one examination record and one suspension proceeding for a contractor’s whole Illinois footprint — so a license problem is a statewide problem, not a problem in one jurisdiction, and it stops every job at once.

Champaign · Champaign County

A shorter mandatory cycle on commercial and institutional systems is recurring, schedulable service revenue rather than emergency call-out work — a different frequency profile on the same policy, and one that puts the contractor’s own license in the evaluator’s chair on somebody else’s property.

Carbondale · Jackson County

An operator whose route mixes exempt on-site mine work with licensed off-site hauling is running two regulatory statuses out of one truck, and the exemption ends the moment the load leaves the mine property — which is precisely the kind of boundary a claim gets argued over after the fact.

Crystal Lake · McHenry County

Whether a surface-discharging job needs its own federal-scheme coverage or rides on the local health department’s general permit is decided by the jurisdiction, not by the contractor — so the same system design carries two different compliance postures on two sides of a line, and the one that is wrong is a discharge without coverage.

Illinois questions we get asked

Does Illinois license septic installers?

Yes, and at the state level. The Illinois Department of Public Health issues the Private Sewage Disposal System Installation Contractor license — the name the Act gives it in its definition section, at 225 ILCS 225/3(8) — and under 225 ILCS 225/5(a) the Director issues it on a passed written examination and the annual fee. The duty sits in the statute rather than in guidance: under 225 ILCS 225/4(a) anyone who does that work on a system other than the one serving his own single family residence “shall be licensed by the Department as a Private Sewage System Installation Contractor”. There is no county register to join on top of that, and no trade association in the credential path. What does sit on top of it is the approval for the particular job, which 77 Ill. Adm. Code 905.190(a) accepts “from the Department or local authority”.

Is designing the system a separate Illinois credential?

No — ordinary design sits inside the installer license, which is worth knowing before you go looking for a credential that does not exist. 77 Ill. Adm. Code 905.180(b)(1) has the examination test “the applicant’s knowledge of the design, installation, operation, maintenance, repair and service of private sewage disposal systems”. Two named exceptions reach other state credentials rather than a septic one: 225 ILCS 225/8(a)(10) admits an alternative private sewage disposal system only where it is designed by a professional engineer licensed under the Professional Engineering Practice Act or by an environmental health practitioner licensed under the Environmental Health Practitioner Licensing Act, and 77 Ill. Adm. Code 905.20(g)(4) lets an Illinois licensed professional engineer propose an alternative pipe-sizing and slope design. So on most jobs the design judgment and the installation judgment rest on one license and one person.

Who does the installer license not reach?

The Act names a class of person and contemplates a class of place. The person, at 225 ILCS 225/4(a): “A person who owns and occupies a single family dwelling and who constructs, installs, maintains, services or cleans the private sewage disposal system which serves his single family residence shall not be required to be licensed under this Act, however, such person shall comply with all other provisions of this Act and the private sewage disposal code promulgated hereunder by the Department.” Owner, occupier, single family, his own residence — and still inside every other provision of the Act. A landlord is outside it, so is a builder, and so is a friend with a backhoe. The place, at 225 ILCS 225/10(a): a unit of local government may keep an ordinance regulating and inspecting these contractors “provided such ordinance establishes a system at least equal to state regulation and inspection”, and “If such plan is approved by the Department the ordinance shall prevail in lieu of the state licensure, fee and inspection program”. This page does not tell you that any Illinois jurisdiction currently holds that approval, because that was not established, and it does not tell you the license runs everywhere untouched either, because the Act provides for the displacement in terms. Ask the local authority for your job which of the two it is.

Does my installer license cover pumping and hauling?

No. Illinois runs two licenses out of one Act, one agency and one rule Part. 225 ILCS 225/4(a) creates the second one in its own words — “any person who cleans or pumps waste from a private sewage disposal system, other than a system which serves his own single family residence, or hauls or disposes of wastes removed therefrom shall be licensed by the Department as a Private Sewage Disposal System Pumping Contractor” — and 77 Ill. Adm. Code 905.180(b)(3) has a person who wants both pass both examinations. Portable sanitation is a third class again, and a two-layered one: a business license under 225 ILCS 225/5b(a) plus a certificate for each servicing technician under 225 ILCS 225/5b(a-5). The state environmental agency issues a hauler none of these. Under 77 Ill. Adm. Code 905.170(f) its permits sit at the receiving end, on the municipality, the lagoon or drying bed or the incinerator taking the load — with one exception worth knowing, because a contractor who builds his own disposal facility needs a construct-and-operate permit in his own name at 905.170(f)(3).

Does Illinois certify septic inspectors?

It certifies nobody as one, and the useful half of the answer is what it does instead. 77 Ill. Adm. Code 905.20(q)(3)(A)(i) puts the evaluation on a compulsory cycle and then closes the list of people who may carry one out: “The system may be evaluated by the homeowner, a Private Sewage Disposal System Installation Contractor, a licensed Environmental Health Practitioner, an Illinois licensed Professional Engineer, a representative of the Department, or an agent of the Department or local health department.” On non-residential property (A)(ii) repeats that list without the homeowner and shortens the cycle to at minimum every 3 years, against the residential minimum of every 5. So there is no inspector credential to go and get, and there is no gap either: the evaluation is owed, the clock is in the rule, and an installation contractor’s own license is one of the things that qualifies him to perform one on somebody else’s system.

Do I need workers compensation, and does my license depend on it?

Two answers, and they do not meet. Yes on the coverage: 820 ILCS 305/3 applies the Act automatically and without election, and the trades it treats as extra hazardous include, second on the list, “Construction, excavating or electrical work.” A septic firm that employs anyone has no threshold to cross and makes no election. 820 ILCS 305/4(a) then gives four routes to secure that liability, none of which is a state fund, because Illinois operates none. No on the license: 820 ILCS 305/4(a-3) reaches a business “engaged in activities requiring licensure by a State agency, for which proof that it has insured its workers’ compensation liability is a requirement for licensure”, and the Private Sewage Disposal Licensing Act imposes no such condition, so that provision does not reach this license. What does reach an uninsured Illinois employer is 820 ILCS 305/4(d): a work-stop order posted at the job site, a Class 4 felony where the failure was knowing, a Class A misdemeanor where it was negligent, and each day a separate offense.
