EPCOR Water Arizona Interim Rate Case Approved

PHOENIX - The Arizona Corporation Commission voted today to approve an interim rate case for the largest water company in Arizona.

EPCOR Water Arizona, Inc. filed an interim rate application with the Corporation Commission on January 31, 2019. The application followed a 2-2 tie vote on the company's attempt to finalize its last application for a rate increase and possible consolidation of water districts before Commissioners in January.

During today's vote, Chairman Bob Burns and Commissioners Boyd Dunn and Sandra D. Kennedy voted in favor of the interim water rate case. Commissioners Andy Tobin and Justin Olson opposed it by voting "no."

EPCOR is a Class A public service corporation providing water and wastewater utility services in various communities in Maricopa, Mohave, and Santa Cruz counties. EPCOR operates 19 public water systems in 11 separate water districts, serving approximately 133,000 water connections in Arizona. The water districts are the Agua Fria District, the Anthem District, the Chaparral District, the Havasu District, the Mohave District, the North Mohave District, the Paradise Valley District, the Sun City District, the Sun City West District, the Tubac District, and the Willow Valley District.

EPCOR is directed to file with the Commission schedules of the interim rates and charges consistent with the rates and charges for all water districts set forth in today's decision. The approved interim rates and charges shall become effective for all service rendered on and after April 1, 2019. EPCOR will also identify any tax credits from last year's federal tax reform act and will pass on any credits to customers. The company is required to file a new rate case no later than May 1, 2020, with a test year ending in December 31, 2019.

All documents related to this matter, including today's decision once signed, may be found on the Corporation Commission's online docket at by searching for docket number WS-01303A-19-0011.
