  • Public Water Systems - Drinking Water

    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, Chapters 4 and 5 relating to Public Water Systems (PWS). A PWS is defined as a water system that serves 15 or more connections, or 25 or more people, for more than 60 days a year. PDEQ is responsible for approximately 160 PWS located in Pima County.

    Operations, Maintenance, Monitoring, and Reporting Compliance

    PDEQ conducts inspections of regulated PWS to ensure that the construction and operation are in accordance with ADEQ's Safe Drinking Water rules. These PWS inspections determine whether minimum design criteria are being met and maintained. PDEQ follows A.A.C. R18-5-502 and ADEQ's Engineering Bulletin 10 to make these determinations. In addition, the requirements for adequate water supply disinfection, described in ADEQ's Engineering Bulletin 8, are also evaluated through inspection and, if necessary, testing and reporting by the system operator. PDEQ makes monitoring and reporting compliance determinations and takes applicable enforcement actions for PWS that are under PDEQ’s authority.
