Need help paying your bill?

Information about flexible payment plans, payment deferrals for low-income seniors and disabled individuals, and discounts for eligible low-income housing residents.

King County Wastewater Treatment Division recently implemented new affordability options for capacity charge customers based on the findings of a Low-Income Customer Affordability Study. The new assistance programs approved by the King County Council and signed by the Executive took effect June 29, 2019. 

Request payment deferral (for low-income seniors and disabled individuals)

If you are enrolled in the State and County property tax exemption program for seniors or disabled individuals, you may be eligible to wait until you sell your property to pay the capacity charge. King County will place a property lien for the balance owed and collect the funds when your property is sold. The interest rate is reduced to 5 percent annually and late fees are waived, however a recording fee will apply.
