When buying or selling a property: 

Please contact our office at (425) 334-8588 to provide us with the correct contact and billing information for the sewer account.  

The billing statements: 

Billing Statements are mailed the first of the month and payment must be received in our office by the 25th of the same month, for that month.

Duplicate Billing: 

If you would like a separate sewer bill mailed to one other party (such as a property management firm or a homeowner’s association) you may now request that service for an additional fee of $1.00 per month. If you would like to start this service please complete the Request for Duplicate billing form.

Since the legal property owner (legal owner of record) is responsible for all sewer fees, this request can only be made by the legal owner. Once the completed form is received we will start the duplicate billing and apply the service fee to your account, starting the following month.
