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)
  • Or, bring them all together as one district (consolidation)

The rate case process takes about a year. The Commission is expected to rule on the case on Jan. 15-16, 2019. View the docket to read the Administrative Law Judge's Recommended Opinion and Order.

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