Water shall not be shut off under section 7-5-6-4 of this chapter or for a violation of rules and regulations affecting utility service until notice and an opportunity for a hearing have first been given the occupant of the premises involved. The notice shall state that if payment is not made before a day stated in the notice but not less than thirty (30) days after the date on which the notice is given, the water supply to the premises will be shut off. The notice shall also state that the occupant may, before such date, demand a hearing on the matter, in which case the supply will not be cut off until after the hearing is held. If the customer requests a hearing before the date specified, a hearing shall be held on the matter by the city council at least one week after the date on which the request is made. If as a result of the hearing, the city council finds that the amount claimed to be owing is actually due and unpaid and that there is no legal reason why the water supply of the delinquent customer may not be shut off, the city may shut off the supply.
