SEWER RA TES PROPOSAL
The proposed sewer rates are calculated to recover and proportionately allocate the City's cost of providing sewer services to each customer class. The proposed sewer rate updates are designed to ensure that the revenue collected from the sewer rate is sufficient to cover, but does not exceed, the City's costs of providing sewer services to its customers. The City's cost of providing sewer services were proportionately allocated to each customer class based on the costs of serving that customer class. The basis upon which the proposed sewer rates were calculated is set forth, in further detail, in the Sewer Rate Study, which can be found on the City's website, will be mailed to any person, upon request, and is available upon request in the Engineering Department.
The City updated and adopted the Sewer Master Plan in March 2024. The Sewer Master Plan identified over $79 million in immediate upgrades needed at the wastewater treatment plant and over $222 million in improvements needed in the collection system to upgrade and replace aging infrastructure. The full Sewer Master Plan can be found on the City's website at: https://www.manteca.gov1departmentslengineeringlsanitary-sewersystem.
The Sewer Rate Study includes the City's 10-year capital improvement program (CIP) for sewer system improvements, which includes approximately $222 million in projects to be completed over the five years between fiscal year (FY) 2025 and FY 2030, including the Wastewater Quality Control Facility (WQCF) Phase IV Stage 1 Expansion Project totaling $151M as well as sewer system improvement projects. The current sewer rates have not changed since 2010 and are in dire need of an increase to pay for system improvements, increase in Operations and Maintenance costs, increase in compliance costs, increase in material costs, increases in labor costs, and to replenish account reserves.
The City Council will consider the following proposed sewer rate updates, set forth in the table below, at the City Council meeting on March 18, 2025:
