Payments are past due when not received within 10 days after the established due date. The utility district should issue a notice of past due payment to the customer, detailing the payment owed and the consequences for failure to pay. The notice should be sent before the mailing date of the next billing. [Ord. 71 § 1607, amended, 1/21/2021; Ord. 66 § 1607, amended, 2/6/2020; Ord. 55 § 1607, adopted, 2/21/2019.]
