Rates shall be established on the basis of the financial requirement to cover the cost of operations, maintenance and replacements, and these costs shall be reviewed annually to assure proportional distribution among users.

The method for determining proportional distribution shall be by determining the average water usage by meter size and the total amount of flow through the wastewater treatment plant on an annual basis.
