*Each additional drainage fixture unit (DFU) beyond the 20 DFU included in the Availability fees will be charged at the rate of $298 (excluding single family residences in residential zones).

  • For wastewater-related plumbing permit fees, such as sewer taps and building sewers, or to obtain a City of Fairfax Plumbing Permit, please refer to Code Administration.

Winter Quarter Limit 

Fairfax City residential wastewater customers are billed a winter quarter limit, which is based on winter quarter consumption multiplied by a factor of 1.3 or actual water consumption during the current billing period, whichever is lower.

Fairfax City Council adopted the winter quarter limit for City of Fairfax wastewater fees in February 2022 to minimize charges for water consumption that does not discharge to the wastewater system (i.e., irrigation and filling pools).

Commercial accounts are not included because these accounts have a master meter that can be supplemented by a sub-meter to measure flow that does not enter the wastewater system.
