Fees & Costs

Connection Fees

Connection fees may apply in circumstances such as new development, changes in use, adding a second living unit, and excessive water consumption. Please contact our Engineering Department with any questions about connection fees at 415- 945-1530.

Please reference the Schedule of Rates, Fees and Charges to view the connection fee per acre-foot (AF) of estimated annual consumption. The installation charges and connection fees are reviewed periodically and are subject to change. The annual consumption for residential use is based on the area average of the neighborhood in which the unit(s) are to be built. All other uses, such as business, industrial, agricultural, or institutional, are based on consumption estimates formulated from information provided by the applicant.

The amount of water purchased at the time of application, based on consumption estimates, becomes the water entitlement for the property to be served. If, at a later date, we determine that actual consumption is exceeding the entitlement, additional connection fees will be assessed to increase the property's entitlement, or the consumption will have to be reduced to the level consistent with the existing entitlement.

All water purchases are subject to the fees in effect at the time the purchase is made. Therefore, it is very important that the information requested by, and submitted to, the district be as accurate as possible.
