Payment Options

Pay or View your bill

1. Pay Online via Invoice Cloud: Make a One-Time Payment, Sign Up for Automatic Payments, or Schedule a Payment.

Payments can be made via the InvoiceCloud portal. Register your account online to be able to use extended features, such as managing payments, notifications, and billing preferences. Customers who register an account will also be able to link and pay multiple accounts with a single payment. A convenience fee of $2.95 will be charged for every transaction. The maximum amount per transaction is $300. If your bill is over this amount, additional transactions will need to be made. You will need your 7-digit account number and must provide the last name of the account holder. 

This link will direct you to the right page.

Your InvoiceCloud account is managed entirely by you. Although we can access it, any changes that need to be made must be made by you (such as paperless setup and updates to credit card information). If you later move and close your account with our office, you must also separately close your InvoiceCloud account. We are not able to do this for you.

2. Automatic Payments Directly with KCWD90 via Checking Account:

When you sign up for Automatic Payments via Checking Account, your payment will be taken directly out of your checking account. This is our recommended payment option, as it is a free service and ensures that your payments will never be late. When you sign up, you will still receive a detailed copy of your bill the first week of your billing month. The amount due will be automatically deducted from your designated financial institution around the 15th of the month following your invoice date. Please use the following link to begin the process:

Please note: If you signed up for Automatic Payments directly with KCWD90 via Checking Account, do not turn on Auto Pay online via Invoice Cloud. This will cancel your free service with our office and change your billing preference to InvoiceCloud, which has a processing fee attached to it. 

3. Pay by Mail:

Make checks payable to KCWD90 or Water District #90. Please allow 4-5 working days when mailing payments, as postmarks will not be considered. Please return your invoice stub with your payment. To ensure proper credit, we ask that you write your account number on the memo line of your check. Please do not staple or tape.

4. Pay by Phone:

Call 1-855-984-1191. A convenience fee of $3.45 will be charged for every transaction. You will need your 7-digit account number and the last name of the account holder.

5. Pay in Person:

Cash, check, and money orders are accepted in person at our administrative office located at 15606 SE 128 ST, Renton, Washington 98059 during our normal business hours, 8:00 a.m. to 4:30 p.m. Monday to Friday. We also have a dropbox located near the entrance of the parking lot. At this time, we are only accepting such payments via our dropbox, as our administrative office is closed to the public until further notice.


Please Note: Doxo is NOT an authorized 3rd-party payer.
