Water and wastewater rate setting is one of local government’s most important environmental and public health responsibilities. The EFC and the Hawai’i Department of Health Safe Drinking Water Branch conducted surveys of what water and wastewater utilities in the state of Hawai’i charge in rates and in connection and system development fees. The EFC compiles the rates data with information on utilities’ Enterprise Fund key financial performance indicators, system characteristics, community socioeconomics, and other data. The Hawai’i DOH SDWB and the EPA 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. The information is compiled annually in the HI Water and Wastewater Rates Dashboard, downloadable spreadsheets, and a summary report.
Surveys included rates data in 2021 (43 utilities); 2016 (35 utilities).
