​Share this page​

​Aquifer protection permits are part of a program enacted under the Arizona Administrative Code (AAC) Title 18, Chapter 9, for regulating sewage collection systems.  Enforcement by the city of Phoenix follows the AAC rules under a Maricopa County health delegation for two separate types of sewage collection systems, public (city owned) and privately owned. 

The pdf forms for public APP 4.01 sewer systems, those constructed by private developers and operated by the city, are found here:

The pdf forms for privately-owned sewage collection systems are found here. Private water systems are not under the Public APP 4.01 sewer systems.
