2017-18 Water Rate Case

According to a September 2015 decision from the Arizona Corporation Commission(AzCC), EPCOR was required to file a water rate case. The company filed the case August 18, 2017, giving the AzCC the information it needs to make a decision on the policy of water consolidation, based on fresh financial data from 2016. The two options are:

  • Keep the 11 water districts the way they are today (status quo/standalone)
  • Or, bring them all together as one district (consolidation)

View the docket to read the Administrative Law Judge's Recommended Opinion and Order, which recommended standalone rates. On Jan. 25, 2019, the Commission failed to reach a decision on the case and it was closed. EPCOR must file an application for interim rates, which will take effect in March 2019. Then, the company must file a new rate case. That process could take 12-24 months, based on the timeline of the 2017-2018 case.

The ACC continues to advocate on Anthem ratepayers' behalf for full or partial consolidation, for rate relief.
