(A) The wastewater service charge for the use of and for service supplied by the wastewater collection system of the city shall consist of a combination of a user charge for operation, maintenance and replacement and a debt service charge, and shall be determined periodically by Council. The total of the user charge and debt service charge for the wastewater collection system shall be the rate set forth in § 52.056.
(B) The debt service charge shall be computed by dividing the annual debt service of all outstanding loans, bonds and the like, by an estimated annual water pumpage to determine a charge per 1,000 gallons of water.
(C) The user charge shall be based on water usage as recorded by water meters. It shall consist of operation, maintenance and replacement costs and shall be computed as follows:
(1) Estimate the projected annual revenue required to operate and maintain the wastewater collection system, including a replacement fund for the year; and
(2) Compute a user rate per 1,000 gallons of water by dividing the amount of revenue and replacement fund required by the number of thousands of gallons of billable flow estimated.
(D) The adequacy of the wastewater service charge shall be reviewed annually by certified public accountants for the city in their annual audit report. The wastewater service charge shall be revised periodically to reflect a change in the debt service charge or a change in operation, maintenance and replacement costs.
