Septic Regulations in Arizona

Rich in Native American history, Arizona is the sixth largest state in the US and is home to the Grand Canyon.

The Arizona Department of Environmental Quality (ADEQ) regulates septic systems in Arizona along with local county health departments acting as the .ADEQ representatives. Those wanting information on septic systems in Arizona should contact both offices to determine the regulation, permitting, and inspections required for the type of septic system being installed.

Regulation of Septic Systems / Septic Contractors in Arizona

The Arizona Department of Environmental Quality standardizes all septic systems in Arizona. Their responsibilities include enforcing municipal wastewater regulations, issuing permits, licensing septic system installers, and managing complaints.

The first step for a homeowner is to file a Notice of Intent (NOI) to Discharge form. The NOI spells out the process of obtaining authorization to construct and operate a septic system.

The ADEQ offers a publication addressing septic systems in Arizona entitled "Minimum Requirements for the Design and Installation of Septic Tank Systems and Alternative On-side Disposal Systems Engineering."

Licensure Requirements for Septic System Contractors

The University of Arizona's Cooperative Extension of Water Quality provides an Onsite Waste Water Education Program at their Maricopa Agricultural Center training facility. This facility has several conventional above ground and alternative systems that are in operation to facilitate training. The conventional septic systems with gravity and chamber trenches are used for inspection training. Septic system contractors receive certification for licensure after completion of this program.

How to File a Complaint

If you are concerned that a local septic system may pose a health risk, your first step is to contact your local county health department. If they cannot help, then contact The Arizona Department of Environmental Quality.
