Wastewater Cost of Service Study


In June of 2014, the Central San engaged Raftelis Financial Consultants, Inc. (RFC) to conduct a comprehensive Cost of Service (COS) study to independently assess and evaluate the District’s existing wastewater rates to provide a fair and reasonable rate structure that enhances the equity of rates to ensure that there is a proportionate recovery of costs from the various customer classes. This report documents the study resultant findings, analyses, and proposed changes.
