The basic items needed are flow rate, energy consumption, and cost of energy. That's all you need if you are trying to determine the cost to pump water. This will give you the cost per unit volume

1 ) Calculate the hourly flow in Gallons, Cubic Meters, etc. per hour

2 ) Divide the hourly power consumption in KWH by the total hourly flow, which gives KWH/Gal

3 ) Multiply KWH/Gal * Cost of electricity in $/KWH which gives $/Gallon (or whatever unit of volume)

This results in the wire-to-water cost including all efficiency losses.
