ADEQ & Yuma County Septic Permit Guide
Arizona licenses septic installation and repair separately from septic pumping — as of September 2026, installers need an Arizona Registrar of Contractors (ROC) CR-41 license, while pumpers need an ADEQ septage hauler permit, not a ROC license. Permits for actual construction work — installing, replacing, or repairing a system — are issued by Yuma County Development Services, not by the state directly.
The two systems get confused constantly, because most homeowners assume "licensed septic company" means one single license. It doesn't. This page walks through who regulates what, exactly what Yuma County charges for a permit, and a real step-by-step way to check a company's license yourself before you hire anyone.
Who Regulates What
Arizona splits septic regulation across two entirely different state agencies, and they don't overlap. Understanding which one applies to your job is the single most useful thing to know before you hire anyone.
Installation & Repair — Arizona Registrar of Contractors (ROC)
Installing a new septic system, replacing one, or repairing an existing one is construction work, and Arizona regulates it as such. A contractor doing that work needs to hold an active ROC license under the CR-41 ("Septic Tanks and Systems") classification. The ROC maintains a public, free license lookup at azroc.my.site.com/AZRoc/s/contractor-search — anyone can search a business name and see its classification and status before hiring.
Routine Pumping & Hauling — Arizona Department of Environmental Quality (ADEQ)
Pumping out an existing tank and hauling away the septage is regulated as a separate, entirely different program — ADEQ's septage hauler permit system, not the ROC. A company that only pumps and hauls, and doesn't install or repair systems, has no reason to hold a CR-41 license and legitimately won't appear in an ROC search. That's expected, not a red flag. What matters for a pumping-only business is whether it holds a current ADEQ septage hauler permit instead.
In short: ROC licenses the contractor who builds or fixes the system in the ground. ADEQ licenses the truck that comes to empty it. A company can legitimately hold one, the other, both, or — if it subcontracts installation work out — neither directly. The only way to know for sure is to check the right registry for the specific work you're hiring for, which is exactly what the walkthrough further down this page covers.
Yuma County Septic Permitting & Fees
ADEQ delegates onsite wastewater facility (OWTF) permitting authority to all 15 of Arizona's counties, and each county administers its own program and sets its own fee schedule under that delegation. In Yuma County, that means Yuma County Development Services — not the state directly — issues septic (onsite wastewater) permits, reviews plans, and inspects installed systems.
These are Yuma County's own delegated fees, and they're distinct from ADEQ's separate statewide Type 4 general permit fee schedule (published at azdeq.gov/SepticSewerFees) for certain onsite wastewater facilities — the two lists shouldn't be conflated. For a project inside Yuma County, the county's own fee schedule below is almost always the one that applies.
Yuma County Onsite Wastewater (Septic) Permit Fees
| Item | Fee |
|---|---|
| Conventional Residential septic permit (single unit) | $360.00 |
| Residential Owner/Builder permit | $650.00 |
| Alternative System, Residential | $620.00 |
| Alteration / Repair permit | Half the applicable new-install fee |
| Plan review — Residential Owner/Builder | $250.00 |
| Plan review — Alternative Residential | $450.00 |
| Field survey consultation | $120.00 |
| Re-inspection | $170.00 |
| ADEQ Transfer of Ownership | $50.00 |
| Septic Pumper Permit | $100.00 |

A quick way to read this table: a brand-new conventional residential system is $360 for the permit itself, while a homeowner acting as their own builder pays $650 plus a $250 plan review. An alternative system (used where soil or site conditions rule out a conventional design) runs $620 for the permit and $450 for plan review. Repairing or altering an existing system is priced at half of whatever the matching new-install fee would be — so the repair fee scales with the type of system involved, not a single flat number.

How to Verify a Septic Company Yourself
You don't need to take anyone's word for their license status — both registries are public and free to search. Here's the real sequence, step by step.
-
Go to the ROC Contractor Search
Open azroc.my.site.com/AZRoc/s/contractor-search — this is the Arizona Registrar of Contractors' public license lookup, and it's free to use.
-
Search by business name
Type in the exact business name the company gave you. If you have their ROC license number instead, you can search by that directly for a more precise match.
-
Confirm the classification and status
Open the matching result and check two fields: the classification should show CR-41 ("Septic Tanks and Systems"), and the status should show Active — not Suspended, Expired, or Revoked. Both need to check out before you treat the company as licensed for installation or repair work.
-
For pumping-only companies, check ADEQ's hauler roster instead
If a company only pumps and hauls septage and doesn't show up in the ROC search, that's expected — it doesn't need a CR-41. Check ADEQ's current septage hauler roster PDF instead to confirm it holds a valid hauler permit for that side of the business.
For pumping-only companies, ADEQ posts its current septage hauler roster as a PDF on its website — that's the registry to check instead of (or in addition to) the ROC, since a pumping-only business legitimately has no reason to appear there.

A Realistic Permit Timeline
Septic permitting isn't same-day. After an application and any required plan review are submitted, plan on the county needing time to review the site details, and on an inspection being scheduled once installation work is underway or complete before final approval is issued. In practice, plan for several weeks between application and final approval for a typical residential project, and build in extra time during the county's busier building season — permit and inspection queues run longer when more projects are moving through the system at once.
The practical takeaway: if a septic installation or major repair is part of a larger project with its own deadline (a home sale, a new construction closing, a well or building permit tied to the same property), start the septic permit process early rather than assuming it can be squeezed in at the last minute. A contractor who regularly pulls permits through Yuma County Development Services can usually give you a more specific estimate for current turnaround times than any general rule of thumb here can.
Step 1
Apply & Plan Review
Submit the application (and plan review, where required) to Yuma County Development Services.
Step 2
Install & Inspect
A licensed CR-41 contractor completes the work; the county inspects before it's covered.
Step 3
Final Approval
Once inspection passes, the county signs off and the permit is closed out.

Frequently Asked Questions
Why don't pumping-only companies show up in an ROC search?
Because they don't need an ROC license to do that work. The Arizona Registrar of Contractors licenses installation and repair contractors under the CR-41 classification. Routine septic pumping and hauling is licensed separately, through the Arizona Department of Environmental Quality's septage hauler program. A company that only pumps tanks — and doesn't install or repair systems — has no reason to hold a CR-41, so it won't appear when you search the ROC database. Check ADEQ's septage hauler roster instead for that kind of business.
What if my business is Suspended or shows a status other than Active?
Don't hire based on a Suspended, Expired, or otherwise non-Active status — or, at minimum, ask the company to explain it before you sign anything. A non-Active status doesn't automatically mean wrongdoing occurred, but it does mean the state isn't currently vouching for that license, and you should get a clear answer directly from the business (or verify a renewal is in progress) before you rely on it.
Do I need a permit just to have my septic tank pumped?
No. Routine pumping and cleaning of an existing tank is maintenance, not construction, and Yuma County's permit fee schedule doesn't include a pumping permit for the homeowner — the fee table above is for installing, replacing, altering, or repairing a system. The one exception is the Septic Pumper Permit, which is a business-level permit the hauling company itself holds, not something a homeowner applies for per pump-out.
Is a Yuma County septic permit the same thing as an ADEQ permit?
They're related but not identical. ADEQ delegates onsite wastewater permitting authority to all 15 Arizona counties, and Yuma County Development Services issues and administers the actual permits and fee schedule described on this page under that delegation. ADEQ also publishes its own separate statewide Type 4 general permit fee schedule for certain onsite wastewater facilities — a different fee list from Yuma County's. If you're unsure which applies to your project, Yuma County Development Services (928-817-5000) is the right first call.
