As a regulated utility, rates for your wastewater service are approved by the Arizona Corporation Commission (ACC). On June 13, 2017, the ACC voted to approve the consolidation of the Agua Fria, Anthem, Mohave, Sun City and Sun City West wastewater districts, phased in over five years and ultimately bringing EPCOR wastewater customers to the same price for the same service, no matter where they live.
