Unpacking the wastewater rate case

Some Anthem residents are confused because their water rates have gone up, when the message has been that rates are going down. Here's how to unpack your water bill, with additional detail from the recent wastewater rate case (which is different than the water rate case).

  • As of July 1, all EPCOR residential customers in Anthem (those ease of I-17) are paying the same, fixed monthly amount for wastewater services. There is no charge based on water usage (as there was prior to this date).
  • After a five-step phase-in period, all EPCOR residential wastewater customers will pay the same, fixed monthly amount of $38.59 (referred to as the “fully consolidated residential rate”).
  • Had the Arizona Corporation Commission rejected the “fully consolidated residential rate,” Anthem customers would be paying $57.75 per month starting July 1, 2017 until a future wastewater rate case.
  • Anthem residential wastewater customers will see the following fixed monthly rates, phased in over five years (EPCOR originally requested three years, but the Commission elected to spread the change over five years, to benefit the communities experiencing an increase, rather than a decrease):
  1. As of July 1, 2017: $59.15
  2. As of July 1, 2018: $55.39
  3. As of July 1, 2019: $51.63
  4. As of July 1, 2020: $47.89
  5. As of July 1, 2021: $38.59

Items to note

  • The rates in steps two through five also may be about $1 to $2 per month higher than what is shown above.  This is due to something the Corporation Commission calls the System Improvement Benefit (SIB).  The SIB is complicated, but essentially it allows EPCOR (and other utilities) to raise rates annually to offset approved expenses associated with major repairs to infrastructure instead of waiting until they file a complete rate case sometime in the future. EPCOR may take this to the Commission later this year or in 2018.
  • After the last step, approximately 6% of the bills from 2015 (those based on 1,000 gallons of water usage or less in a month) will be higher than what was billed in 2015; but 94% (those based on 2,000 gallons of water usage or more in a month) will be lower. The fact that this case benefited 94% of Anthem residents is the reason why the Anthem Community Council supported consolidation.
