  • Subdivision Sanitary Facilities

    The Pima County Department of Environmental Quality (PDEQ) has delegated authority from the Arizona Department of Environmental Quality (ADEQ) to enforce applicable requirements of the Arizona Administrative Code (A.A.C.) Title 18, Chapter 5, Article 4 relating to subdivisions. PDEQ issues a Certificate of Approval of Sanitary Facilities for Subdivisions upon receipt of service agreements for drinking water and garbage collection and disposal.

    View the Subdivision Administrative Submittal Checklist for instructions and guidance on obtaining the Approval of Sanitary Facilities and submit the documents listed in the Forms tab below.

    Note: Subdivisions served by onsite wastewater treatment facilities require the submittal of the Septic Concept Approval letter, while subdivisions served by sewer require a copy of the sewer Construction Authorization.


    Special Notice: Starting July 25, 2016, PDEQ will only accept electronic submittals for water, sewer and Approval of Sanitary Facility projects. Applications must be submitted electronically in PDF format by either emailing all forms and plans to sewer@pima.gov, providing an FTP download link in the application email, or by having a USB flash drive or CD delivered to Development Services' office (201 N. Stone Ave.). Please note that the sewer@pima.gov inbox will only accept files less than 20 MB in size, so anything larger must be submitted using one of the alternate methods.
