Arizona septic rules
Septic pumping rules in Arizona.
Arizona requires a state license or permit, and local health departments can add their own. Below: who regulates, what pumpers have to keep, and where to find the official forms. Checked against official sources on October 8, 2026.
The rules
What a pumper in Arizona should know.
A guide, not legal advice. Counties and local health departments can add their own rules on top of the state's, so check with the county where the system is.
We could not read every page on the Arizona agency's own site, so parts of this guide rest on the rule text and county pages. Confirm the details with the agency before you rely on them.
- Who regulates septic systemsState and local
Arizona Department of Environmental Quality (ADEQ), Water Quality Division onsite wastewater program, with delegated county agencies. ADEQ sets the rules (A.A.C. Title 18, Chapter 9) and delegates parts of the program to county agencies; for example Pima County DEQ inspects and licenses septic tank cleaners under authority delegated by ADEQ, and Maricopa County processes Notices of Transfer.
- Pumper and hauler licensingState and local
In Pima County, septic tank cleaners must obtain PDEQ licenses for the business and for each vehicle before collecting waste, vehicles are inspected, and PDEQ forwards an ADEQ Septic Tank Cleaner (Pumper) License application to ADEQ, which issues a permanent, non-transferable vehicle license number that must be posted in 3-inch numbers on the rear of the tank and both side door panels.
Licensing details- Where septage can go

- Inspections
Anyone selling or transferring property served by an on-site wastewater facility must have a qualified inspector inspect it within six months before transfer (A.A.C. R18-9-A316); the inspector gives the Report of Inspection to the seller, significant waste must be pumped from each tank, and the buyer files a Notice of Transfer within 15 calendar days after transfer (Maricopa County fee $60 per parcel).
Inspection rules- The rule book
A.A.C. Title 18, Chapter 9, Articles 1 to 4 (onsite wastewater under the Aquifer Protection Permit program, including R18-9-A316 transfer inspections)
Official forms
Get the forms from the source.
We link to the state's own pages instead of keeping copies, because forms change. Your county may use its own forms as well, and those are the ones an inspector will expect.

Questions
Do I need a license to pump septic tanks in Arizona?
Arizona requires a state license or permit, and local health departments can add their own. In Pima County, septic tank cleaners must obtain PDEQ licenses for the business and for each vehicle before collecting waste, vehicles are inspected, and PDEQ forwards an ADEQ Septic Tank Cleaner (Pumper) License application to ADEQ, which issues a permanent, non-transferable vehicle license number that must be posted in 3-inch numbers on the rear of the tank and both side door panels.
Where do I get Arizona septic forms?
From the state's own pages, linked on this page. Many counties and local health departments use their own forms on top of the state's, so check with the county where the system is too.
Does PortaPro come with Arizona forms built in?
No. Forms change, and counties use their own, so PortaPro doesn't ship copies. You upload the current PDF from your county or state once, place the fields on it, and PortaPro fills it from each job: customer, site, tank, gallons pumped and technician. When the agency updates its form, you upload the new one.
How current is this page?
We read the official sources listed at the bottom on October 8, 2026. Rules and forms change, so treat this as a starting point and confirm with the agency before you rely on it. This is not legal advice.
