        (17) on or after the effective date of this
    
amendatory Act of the 100th General Assembly, bill for any utility service, including previously unbilled service, supplied to a residential customer within 12 months, or a non-residential customer within 24 months, after the provision of that service to the customer; however, the water commission may bill for unpaid amounts that were billed to a customer or if the customer was notified that there is an unpaid amount before the effective date of this amendatory Act of the 100th General Assembly for service that was supplied to the customer before January 1, 2016. The time limit of this paragraph shall not apply to previously unbilled service attributed to tampering, theft of service, fraud, or the customer preventing the utility's recorded efforts to obtain an accurate reading of the meter. The commission shall: (i) label any amount attributed to previously unbilled service as such on the customer's bill and include the beginning and ending dates for the period during which the previously unbilled amount accrued; (ii) issue the makeup billing amount calculated on a prorated basis to reflect the varying rates for previously unbilled service accrued over a period of time when the rates for service have varied; and (iii) provide the customer with the option of a payment arrangement to retire the makeup bill for previously unbilled service by periodic payments, without interest or late fees, over a time equal to the amount of time the billing was delayed. The commission shall not intentionally delay billing beyond the normal bill cycle.
