Delinquent Accounts

An unpaid bill becomes delinquent if payment is not received within 60 days from the statement date and will incur late fees. The customer is then sent a written notice of intent to disconnect service for failure to pay the bill. If the bill has not been paid after the final warning, service will be discontinued. If the District is unsuccessful in collecting on the account, the bill will be turned over to a collection agency. There is a charge for checks returned due to insufficient funds.
