Challenges: Size of agency, geographic location, overall demand, etc. Using water rates to measure operational efficiency Non Rate Revenues Many agencies receive non-rate revenues, i.e. property tax, which offset water costs and affects water rates Data change California State Controller Office made changes in data format for special districts in 2019.

Data availability note and assumptions Water Suppliers - & f (aka. MWDOC Rate Survey) which was used to provide data on rates structure (incl. fixed vs commodity rates) and on population served by the water districts. This hinders our ability to precisely report Expenditure Per Capita figures. 20 May 13, 2021 Mesa Water District Cost Comparison Study
