Septic Research Request

The Environmental Services Department of Maricopa County maintains all records of its existing permitted septic systems in a database for posterity.

Please note: Property owners are responsible for keeping accurate records of the septic system location and maintenance for the life of the septic system.

Onsite systems with a failing tank or disposal field will require an Alteration Permit.
