    Sewer Construction

    Plan Review Program

    The Pima County Department of Environmental Quality (PDEQ), acting in accordance with delegated authority from the Arizona Department of Environmental Quality (ADEQ), reviews and approves plans for new construction of public and private sewage collection system extensions, modifications, and relocations of gravity sewer mains, manholes, forcemains and lift stations. All public and private sewage collection systems are required to obtain a Construction Authorization from PDEQ prior to beginning construction, and a Discharge Authorization (a General Aquifer Protection Permit 4.01) to operate the system. For plan review submittal requirements or for information on Applicability Determinations, please refer to the tabs below.

    Process for Plan Review Approval

    Public v. Private Systems: Differences in Submittal Requirements

    Public sewage collection systems are those owned and operated by Pima County, the Town of Marana, and the Town of Sahuarita; all other sewage collection systems in Pima County are private. The differences between the submittal processes are as follows:
    • Public Sewage Collection Systems located in Pima County do not require an Operations and Maintenance Manual in order to obtain the CA.
    • Public Sewage Collection System plans for Pima County must be signed by the proper public sewer authority before PDEQ’s review.
    ADEQ Sewer Approval (private, Marana, and Sahuarita)
