A deposit shall be made with each application, this sum to be retained by the City to ensure payment of all bills. When service to the applicant is discontinued, this deposit, less any amount still due the City for water service, shall be returned when the user presents the receipt for the deposit with the final bill. When water service is for an owner of the premises to be served, no such deposit will be required. (Ord. 78-11, 3-6-1978; 1997 Code)
