CITY COUNCIL REGULA MEETING AGENDA PACKET _Revised_ 6-2-26

City of Pleasanton Sewer Rates & Connection Fees Technical Memo Water Resources Economics Page 4 MULTI-YEAR SINGLE FAMILY CUSTOMER IMPACTS Multi-year impacts on Single Family customers were evaluated by comparing historical bi-monthly bills with projected bi-monthly bills under the proposed rates. Pleasanton Collection charges represent the City’s sewer collection costs, and Treatment Passthrough charges represent DSRSD treatment costs. The total bill is the sum of these two charges. From prior to FY 2019 through FY 2026, the average total bill increased from $77.28 to $91.95, with approximately 65% of the increase attributable to Treatment Passthrough charges from DSRSD. Overall, most historical bill increases have been driven by regional Treatment Passthrough cost increases outside the City’s control. Pleasanton Collection charges have either remained unchanged (FY 2021 through FY 2023) or increased based on CPI (Consumer Price Index) adjustments to cover inflationary cost increases. However, CPI adjustments alone typically are not sufficient for new operating costs or CIP projects required to maintain the City’s sewer collection infrastructure.
