If usage exceeds 6 units, then the water customer shall pay the minimum charge plus the commodity delivery charge and capital improvements charge provided in subsections (b) and (c).


(1) The City Manager is authorized to administratively adjust water rate charges on an annual basis, based upon actual increases incurred by City for acquisition of ground water and imported water. Such adjustments shall take effect on or after July 1st of each fiscal year.

(2) The rate adjustment shall be calculated pursuant to the following formula: The percentage of pumping rate shall be multiplied times the cost of ground water per acre foot and added to the product of the percentage of imported water times imported water costs. This shall yield an average cost per acre foot. The existing per acre foot cost shall then be subtracted from the new total per acre cost under this formula. The difference between the two shall then be divided by 435.6 billing units per acre foot. The product of this division shall then constitute the new additional cost per billing unit.
