2026 water rate case

EPCOR has filed a water rate case with the ACC to review rates across six Arizona districts, supporting reliable service, infrastructure, and long-term water sustainability.

EPCOR has filed a rate case application with the Arizona Corporation Commission (ACC) requesting review of updated water rates for Gateway (Mohave), Paradise Valley, Rio Verde, Sonoran, Sun City and Sun City West water districts.

Across these districts, water rates have remained the same for over five years while the cost of providing safe, reliable water service has increased. At the same time, we are also planning for long-term supply challenges, including drought, groundwater pressures, population growth and changing conditions affecting regional water resources.

The 2026 water rate case is intended to support safe and reliable water service by addressing updated costs, infrastructure investments, and long-term planning to support water reliability.

We are hosting a combination of virtual and in-person community meetings to share what is being proposed and how customers can participate in the ACC public process for this rate review, which will take at least one year or longer. No changes will take effect unless approved by the ACC.
