Arizona Septic Regulations
Arizona septic systems are regulated by the Arizona Department of Environmental Quality (ADEQ) under the Aquifer Protection Permit (APP) program and On-site Wastewater Treatment Facility rules. Permits are required for the installation, construction, and operation of on-site wastewater treatment facilities. Time-of-transfer inspections are not mandated statewide.
- ADEQ issues Aquifer Protection Permits (APP) for on-site wastewater treatment facilities with a design flow greater than 3,000 gallons per day.
- Conventional septic systems with a design flow of 3,000 gallons per day or less are typically permitted by the county under ADEQ delegation.
- A site evaluation including soil testing is required before permit approval to determine suitability for effluent disposal.
- Arizona requires licensed installers and inspectors for on-site wastewater system installation and maintenance.
- Arizona does not mandate a statewide time-of-transfer septic inspection, but property buyers should request system records from ADEQ or the county.
- ADEQ maintains an online database of permitted on-site wastewater facilities — search the ADEQ eMaps or records system before purchasing property.
