The applicable Wet Weather Facilities Charge for each parcel is computed in conformance with the schedule of rates and charges in Resolution No. 35350-23, adopted by the Board of Directors on June 13, 2023, establishing the water and wastewater systems’ schedules of rates and charges subject to Proposition 218, including the Wet Weather Facilities Charge for the Fiscal Year commencing July 1, 2024.

FY25 Wet Weather Facilities Charge

The Wet Weather Facilities Charge (WWFC) was established in 1987 (Resolution No. 31890) to recover the ongoing capital costs of implementing the District’s wet weather program. The program provides storage, conveyance, and treatment facilities for the excess wastewater flows that enter the sewer collection system during wet weather in order to prevent the release of untreated wastewater to San Francisco Bay.

The WWFC funds capital expenses associated with wet weather flows, including maintenance, replacement and rehabilitation of the District’s wet weather facilities. The WWFC is assessed on every developed parcel within the boundaries of EBMUD’s Special District No. 1 (Wastewater Service Area) that has a connection to a community sewer collection system.

The WWFC is billed annually in two stages, first on taxable parcels and later on tax-exempt parcels (mainly public agencies). The charge on taxable parcels is billed on property tax bills through the Tax Collectors’ offices in the counties of Alameda and Contra Costa. While not a tax, the WWFC is collected on property tax bills under agreements with the counties of Alameda and Contra Costa in order to separate it from regular sewage treatment charges. For tax-exempt properties, that do not receive tax bills, the charge is billed during the April to June billing periods directly to the exempt property owner by the District. Customers on taxable properties whom the District is unable to charge via tax roll are also billed by the District at the same time as exempt parcels.
