In order that the rates and charges for sewage services may remain fair and equitable, and be in proportion to the cost of providing services to the various users or user classes, the city shall cause, on an annual basis, a study to be made within a reasonable period of time following the normal accounting period. The study shall include, but not be limited to, an analysis of the costs 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 operation and maintenance, replacement, debt service requirements and capital improvements to the waste treatment system. The studies shall be conducted by officers and/or employees of the city, or by a firm of certified public accountants, and/or by a firm of consulting engineers with experience in such studies.
