April 2020 - payment plan options

King County Wastewater Treatment Division is offering relief for capacity charge customers financially impacted by the COVID-19 outbreak.

To discuss payment plan options, please contact the Revenue & Accounts Receivable Program at: capchargeescrow@kingcounty.gov or by phone at 206-296-1450.

The following relief options are available for capacity charge customers:

  • Deferral of one capacity charge invoice for up to one year.
  • Flexible payment plan offerings including due date extensions with no interest and late fee penalties.
  • No Intent to File Lien notifications mailed to delinquent customers during this time.
     

Since 1990, King County has levied a capacity charge on structures with new connections to the sanitary sewer system. This charge is paid in addition to the monthly sewer bill assessed by the local sewer district.

The capacity charge:

  • Helps King County cover the costs of sewer improvements.
  • Supports expansion projects needed to serve new growth.
  • Does not exceed the cost of capital facilities necessary to serve new connections to the sewer system.

Newly connecting customers are directly billed by King County for the capacity charge.

Elected officials, sewer utility representatives and jurisdiction officials were all involved in King County’s decision to implement a capacity charge to ensure that “growth pays for growth.

2020
Capacity charge $66.35

Listed rates are for 1 residential customer equivalent (RCE) per month. Capacity charge rates go into effect for new sewer hook-ups on or after January 1 each year.
