A public water system that is not otherwise regulated by a municipality or municipal improvement district may terminate water service to a water user when the water user:
(1) Is more than twenty-five (25) days past the earliest due date shown on the face of the bill in making a payment for water, wastewater, or sewer service to the public water system or other public entity; and
(2) Has been sent notice via the United States Postal Service to an address provided by the water user that service will be terminated in no less than fifteen (15) days from date of mailing if the balance due on the service and any applicable late fees are not paid.
