Payment Options

Pay or View your bill

1. Automatic Payments via Checking Account

With this option, your payment will be taken directly out of your checking account. This is our preferred payment method because it is a free service and ensures that your payments will never be late. The amount due will be automatically deducted from your bank around the 15th of the month following your invoice date. You will still receive a copy of your bill.

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

2. Pay Online

Make a one-time payment or sign up for automatic payments via InvoiceCloud. A processing fee of $2.95 will be charged for every transaction. You will need to provide your 7-digit account number and the last name of the account holder. 

Click here to access InvoiceCloud. 

Register your account online 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. The maximum amount per transaction is $300. If your bill is over this amount, additional transactions will need to be made. 

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.

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 processing fee of $3.45 will be charged for every transaction. You will need to provide 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 128th Street, 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.
