Since 2014, the EFC has surveyed nearly all of the rate-charging water and wastewater utilities in Arizona. Utilities are invited to provide their current water and wastewater rates. The EFC compiles the rates data with information on utilities’ key financial performance indictors, system characteristics, community socioeconomics, and other data. The Water Infrastructure Finance Authority of Arizona funds this work to provide utilities across the state with the most comprehensive resources that can be used for benchmarking, rate-setting, financial decision-making, and communication. Partners include the Arizona Municipal Water Users Association, League of Arizona Cities and Towns, Northern Arizona Municipal Water Users Association, and Water Resources Research Center at the University of Arizona. The information is compiled in the AZ Water and Wastewater Rates Dashboard, downloadable spreadsheets, and a summary report.

Surveys included rates data in 2014 (373 utilities), 2015 (354 utilities), 2017 (421 utilities), 2019 (411 utilities), and 2021 (409 utilities).
