Wastewater Capacity Fee

A capacity fee is assessed to each new customer or each existing customer who increases demand for treatment processing on or after July 1, 1984, measured in wastewater volume and strength.

The capacity fee is a one-time charge based on the maximum monthly wastewater volume and average strength calculated at the following rates. The Wastewater Capacity Fee for a Single Family residence (BCC 8800) is $3,130. The fees for Multi-Family units (BCC 6513 and 6514) are $1,720 per dwelling unit 500 sq. ft. or less and $2,200 per dwelling unit greater than 500 sq. ft.

Flow (volume) $15.78/unit*/year
COD $1.65/pound/year
TSS $7.58/pound/year

*1 flow unit = 1 Ccf = 100 cubic feet = 748 gallons

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. Property owners 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.

Assessor Parcel Lot Size Amount (FY 2025)
Small Lot (0-5,000 sq ft) $147.38/year
Medium Lot (5,001-10,000 sq ft) $230.16/year
Large Lot (>10,000 sq ft) $526.00/year

*Collected on the property tax bill. For properties that do not receive a property tax bill, charges will be billed directly to the property owner.

SF Bay Commercial Pollution Prevention Fee

All non-residential customers in EBMUD's Wastewater System are billed a monthly SF Bay Commercial Pollution Prevention fee to fund the EBMUD Pollution Prevention Program. The monthly fee is $5.48. A separate fee is applicable to BCC 8800, BCC 6513, and BCC 6514, the residential BCCs, as noted below.

SF Bay Residential Pollution Prevention Fee

All residential customers in EBMUD's Wastewater System, including BCC 8800, BCC 6513 and BCC 6514, are billed a monthly SF Bay Residential Pollution Prevention fee to fund programs to reduce residential pollutant loadings to the treatment plant and San Francisco Bay. The monthly fee is $0.20/month per dwelling unit up to five dwelling units.
