Key adjustments to the Capital Maintenance Fee (CMF) are available for customers who have upsized meters due to indoor fire sprinklers or low water pressure, and for customers who qualify for our income-based fee waiver program.

Customers whose meter sizes were increased to accommodate indoor fire sprinklers or low water pressure may qualify for lower fixed fees. This fee adjustment would apply to the CMF as well as other fees that are based on meter size. Customers can apply for the adjustment online by submitting an online Capital Maintenance Fee Adjustment Application or by calling 415.945.1506.

Customers who qualify for income-based fee waivers will also receive a CMF waiver, which is in alignment with their current fee structure. This bill adjustment will automatically be applied to those currently receiving discounts through our income-based Service Charge Waiver program. To learn more, contact Customer Service at 415.945.1400.
