Billing Information

Understanding Your Bill

Bill Cycles & Due Dates

MWWD bills every two months for the preceding two months of service. Your bill will be due on the 15th of every even-numbered month (June, August, etc). A green Reminder Notice will be sent out if your bill is 15 days past due. If the account still has not been paid in full within 30 days of the due date, a yellow Delinquent Notice will be mailed, as well as a 10% late fee added to the account. If MWWD bills the property for water service, a Notice of Termination will be mailed out when the account is 45 days past due, and a $20 fee will be added to the account. Water Service will be terminated for non-payment if the account is not paid by the termination date as provided on the Delinquent Notice and Notice of Termination. Your account must be paid in full to reactivate water service.

If MWWD only bills your property for sewer service or storm water service (on behalf of the City of Mukilteo), then instead of a Notice of Termination, a Notice of Lien will be mailed to the property owner. If not paid by the due date listed on this notice, a lien against the property will be certified at Snohomish County, and all lien processing fees added to the account. Continued non-payment will result in foreclosure processing.


A list of current charges can be found here. Please note that the bi-monthly flat rate for water does not include consumption; this is billed additionally to the flat rate. The flat rate plus consumption (listed as "Cons" on your bill) is one line item, starting with the size of your water meter (3/4", 1", etc).

Usage History

The graph for usage history tracks usage over the last year. Current consumption is an orange bar, while last year's consumption for the same bill cycle is a blue bar. The size of the overall graph will fluctuate, increasing with high consumption and decreasing if your consumption levels go down.
