Notice and timing
How delinquency is handled
Grace period after the due date
Bills are due 21 days after the billing date. A bill becomes delinquent after the printed due date; the customer-rights material says a delinquent charge may be applied, but it does not publish the amount in that brochure.
Late-fee calculation
The current customer-rights material states that a delinquent charge may apply to accounts not paid in full by the due date, but it does not state a numeric percentage or fixed charge. Customers with past-due balances can use MyWater to request an installment plan: residential customers pay 25% up front, the remainder over an agreed schedule up to six months, and all future bills on time.
Disconnection timeline
Water bills are due 21 days after billing and become delinquent after the printed due date. Missouri American Water mails written notice at least 10 days before discontinuing water service; wastewater-only customers receive at least 30 days' notice. Service can be disconnected if the bill remains unpaid, subject to Missouri PSC rules and customer protections.
