to Keep Your Septic Tank Healthy: Tips and Tricks

to Maintain Your Septic System and Avoid Costly Repairs

Septic Regulations in Arizona

Arizona, known for its rich Native American history and being home to the Grand Canyon, is the sixth largest state in the United States.

Regulatory Oversight and Contact Information- The Arizona Department of Environmental Quality (ADEQ) serves as the regulatory body for septic systems in Arizona, working in collaboration with local county health departments. Individuals seeking information on septic systems in Arizona should contact both the ADEQ and their respective county health departments to determine the specific regulations, permitting requirements, and inspections applicable to their intended septic system installation.

Regulation of Septic Systems / Septic Contractors in Arizona

The ADEQ plays a key role in standardizing septic systems throughout Arizona. Their responsibilities encompass enforcing municipal wastewater regulations, issuing permits, licensing septic system installers, and managing any related complaints.

For homeowners, the initial step involves filing a Notice of Intent (NOI) to Discharge form, which outlines the process of obtaining authorization for the construction and operation of a septic system.

The ADEQ provides a publication titled “Minimum Requirements for the Design and Installation of Septic Tank Systems and Alternative On-site Disposal Systems Engineering,” which offers comprehensive guidelines on septic systems in Arizona.

Licensure Requirements for Septic System Contractors

The Cooperative Extension of Water Quality at the University of Arizona offers an Onsite Wastewater Education Program at their training facility, the Maricopa Agricultural Center. This facility includes various operational conventional above-ground and alternative septic systems, which are used for training purposes. Conventional septic systems with gravity and chamber trenches are utilized for inspection training. Upon completion of this program, septic system contractors receive certification that qualifies them for licensure.

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.
