A Public Water System (PWS) is defined as a water system which serves
15 or more connections, or 25 or more people, for more than 60
days a year. There are approximately 200 currently identified PWS in Pima
County.
PDEQ is responsible for inspecting these systems to
ensure construction and operation in accordance with ADEQ's Safe Drinking Water rules. These inspections of well sites, pressure and storage tanks, treatment equipment and distribution systems,
verify that minimum design criteria, detailed in A. C. C. R18-5-502 and ADEQ's Engineering Bulletin 10, is met and maintained. The requirements for adequate water supply disinfection, detailed in ADEQ's Engineering Bulletin 8, are also reconciled through inspection and, if necessary, testing and reporting by the system operator.
PDEQ is responsible for identifying new water systems that meet the definition of a PWS, and working with operators and responsible parties to ensure production and distribution of safe drinking water.
