Welcome to the new Payment Portal for King County Water District No. 20

If you have any questions or concerns about this new service please don't hesitate to call the District office at 206-243-3990

When setting up AutoPay, please note:

  • 1) If you set up AutoPay AFTER the current bill has been processed, the balance will NOT be drafted until the next bill is processed.  If you do not want two bills to draft at the same time, you will need to pay the balance prior to when the next bill is processed.
  • 2) The debit to your bank account happens ten (10) days after the bill date (bill dates are the 20th & 30th)
  • 3) Make sure the routing number and account number are entered on the correct line to avoid payment rejection.
