(A) In order that the rates and charges for sewage services may remain fair and equitable and be in proportion to the cost of provided services to the various user classes, the city shall cause a study to be made within a reasonable period of time following the first two years of operation, following the date on which this subchapter goes into effect. Such study shall include, but not be limited to, an analysis of the cost associated with the treatment of excessive strength effluents from industrial users, volume and delivery flow rate characteristics attributed to the various users or user classes, the financial position of the sewage works and the adequacy of its revenue to provide reasonable funds for the operation and maintenance, replacements, debt service requirements and capital improvements to the sewage treatment systems.
(B) Thereafter, on a biennial basis, within a reasonable period of time following the normal accounting period, the city shall cause a similar study to be made for the purpose of reviewing the fairness, equity and proportionality of the rates and charges for sewage services on a continuing basis. 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 such 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.
