Running Costs of Electric Well Water Pump.

Could anyone give me a "ball park" figure for the electrical cost per gallon of pumping well water to my home. Submersible pump fitted on currently disused well ( back up to mains water system). Would like to see if use of this is an option before water charges arrive !. Thank you for any information.

this is a general rule of thumb on basic electricity

A one-horsepower motor is approximately 700 watts.

The motor on a sump pump can be 1/16 - 1/3 HP or bigger ones at 1/4 HP (horse power)

If the pump runs a total of one-hour per day then take the electricity charge that you are paying x the HP of the motor in watts +/- and drag on the motor

Example: for one hour at 250 watts x €0.25/kwh = €0.0625

Think of it similar to turning on a 50 or 100 watt light bulb

Thanks Penury. As far as I remember the pump output is 300 gals/hour, so that should let me do the calculations, Thank you.
