Water Quality Division: Engineering Review: Sewage Collection Systems Review

The section provides details on how to submit an application for a Construction Authorization or a Discharge Authorization for Sewage Collection Systems. A Construction Authorization is a permit that allows an applicant to construct a sewage collection system, and a Discharge Authorization is a permit that allows an applicant to discharge to a downstream sewage collection system or a wastewater treatment plant after construction and final testing have been completed.

Sewage collection systems comprise pipelines, manholes, pumping stations, force mains, and all other structures and devices that collect and transport sewer from residential, commercial and industrial buildings to a sewage treatment facility or to an on-site wastewater treatment facility. The approval of the installation of sewage collection systems is conducted by the engineering review unit within the Aquifer Protection Permit (APP) program of the Water Quality Division.

ADEQ Form 222 is the Completeness Review Guide for Engineering Review that provides a quick overview of the requirements for application submittals for Subdivisions, Sewage Collection Systems, and On-site Wastewater (Septic) Treatment Facilities. In addition, applicants must consult the Delegation Agreement Matrix to determine where the application must be submitted. The Application Fees section can be used to determine the applicable fees for this type of application. Information on the maximum length of time that ADEQ is allowed in order to process this type of review can be found under Application Processing Times.

  • Design Report
  • Capacity Assurance Certifications

The primary components necessary to obtain a Discharge Authorization Permit are:
