Each year the District publishes a Consumer Confidence Report for each water system. To save money and resources, the report will no longer be mailed automatically to each customer. Each annual report is available online. Your bi-monthly water bill is a statement for water service charges covering dates already passed. Per Washington law, your balance is due upon receipt. The due date of the 10th of the month is set to accommodate the collection of delinquent charges according to regulations for municipal corporations.
