This annual report details the results of a statewide survey of water and wastewater rates and rate structures conducted by the Water Infrastructure Finance Authority of Arizona (WIFA) and the Environmental Finance Center (EFC) in 2015. Residential and non-residential drinking water and wastewater rates and rate structures are analyzed for almost 400 water and wastewater utility rate structures throughout the state of Arizona. This report answers frequently asked questions about what utilities are charging, their rate structure designs, billing practices, rate increases, affordability and cost recovery.


The purpose of the report, which analyzes residential and commercial data, is to support utility financial management and pricing efforts by providing a detailed survey of current statewide drinking water and wastewater pricing and financial trends. Report highlights include:

  • NEW: Reclaimed water rates
  • NEW: Commerical rates
  • NEW: Watersheds
  • EXPANDED: Historical pricing trends
  • Five myths about pricing
  • Overview of base charges, variable charges, and rate structures
  • Monthly bills and observations of note
  • Conservation pricing signals
  • Financial impacts on customers
  • Are prices covering all costs?


The summary report is one of several products (including an interactive Rates Dashboard, data tables, and utility rate sheet summaries) created at the conclusion of the annual survey. All of the products can be viewed on the project page shown below.
