How to pay your water and sewer bill

  • IN-PERSON payments are also accepted at 6723 S 124th St, Seattle WA 98178 between 7:30am and 4:00pm. 

  • AFTER-HOURS DROP BOX is conveniently located at the southwest corner of the building, adjacent to the flag pole. Please do not leave cash payments in the drop-box.

With Auto Pay, you can save on postage, pay your bill even when you're out of town, and never have to worry about your payment getting lost in the mail.

The payment will show on your bank statement as a regular transaction. To sign-up, complete and return an Auto Pay Authorization form along with a voided check.

Past due payments must be received in our office by 4:00 PM on the date of your final shut off notice. Please bring your payment directly to the District Office to avoid disconnection of service.

We recently learned that some third-party online bill payment service providers have designed their websites to appear like Skyway’s payment web page, using the District’s logo, contact information and reputation to market their services to potential customers. They are NOT affiliated with Skyway! We do not require that our customers use a separate third-party bill payment service to pay their bill online. These companies frequently charge an additional service fee for your payment, and posting of the payment to your Skyway account may be delayed. If payment is delayed, it may result in late fees being assessed to your account, or your account may be subject to water shut-off or sewer lien.

Skyway Water and Sewer District offers online bill payment through a secure portal on our website: www.skywayws.orgThe District does not charge a fee for online bill payments through our website or phone payments.


If you have any questions, please call our office at 206-772-7343

Bills are delinquent if not paid by the due date. Delinquent accounts are subject to late penalties, service charges, disconnection and or property lien.

How Can I Get Help with My Bill?

Turn-offs and Property Liens

Accounts that are over 60-days delinquent will generate a Past Due Notice. If the Past Due Notice is unpaid, a Final Shut-off Notice or a Property Lien Notice will be sent . A water shut off date or lien filing date will be indicated on this notice. It is extremely important that you note this final date as no further notices will be given. If payment is not received by 4:00 PM on the due date indicated, water will be shut off to your property or a property lien will be filed. Additional Charges of $60 for accounts scheduled for water turn off or $18 Lien Filing Fee and will be levied on the account. A subsequent fee of $18 is charged to release the lien. Water service will not be restored or the property lien will not be released until the past due portion of the account and the added fees have been paid in full.

Inherited Balances from Previous Owners

Unlike other utilities, water and sewer charges are associated with the property rather than with the occupant who incurs the charges. Although a final bill is generated for the previous owner, if left unpaid, this responsibility is inherited by the new property owner (RCW 57.08.080).

Discounted rates for Senior and Disabled Customers

To qualify, you or your spouse must be low-income, 62 years of age or older, or on SSI Disability. Your maximum gross income must not exceed the limits noted on the rate Discount form. Annual renewal is required.

Leak Adjustments

Leaks that occur on the customer side of the meter are the property owner's responsibility to repair. However, you may be eligible for a one-time partial adjustment to your water bill. Adjustments will be calculated on the difference between the wholesale and retail water rate of the excess (above average) water consumption for the billing period in which the leak occurred. ***No Toilet Leaks will be considered***
