(B) Thereafter, on a biennial basis, within a reasonable period of time following the normal accounting period, the city shall cause a study to be made for the purpose of reviewing:
(1) The sufficiency of the revenues to properly operate the wastewater treatment facility and all appurtenances attached thereto; and
(2) Maintaining proportionality among the user classes of the rates and charges for sewage services.
(C) The studies shall be conducted by officers or employees of the city, or by a firm of certified public accountants, or a firm of consulting engineers which firms shall have experience in such studies, or by the combination of officers, employees, certified public accountants or engineers as the city shall determine to be best under the circumstances. The city shall upon completion of the study, revise and adjust the rates and charges as necessary in accordance therewith in order to maintain the proportionality and sufficiency of the rates.
