How much does it cost to run a electric water pump?
A typical electric water pump draws about 750 watts. Used 3 hours a day, that works out to roughly $0.38 per day, $11.63 per month, and $139.61 per year on an average electricity rate of 17¢ per kWh. Submersible and centrifugal pumps for wells or pools consume significant power proportional to flow rate and pressure requirements.

The number that matters most is your own electricity rate. Rates range from under 11¢ per kWh in some regions to over 30¢ in others, so the same electric water pump can cost two or three times as much depending on where you live. Enter your exact rate in the calculator above to get a figure tailored to your bill.
Water-related appliances like the electric water pump spend most of their energy heating water, which is one of the largest controllable costs in a typical home. Lowering the target temperature a few degrees and insulating pipes or tanks both push the annual figure down.
At 750 watts, the electric water pump is a moderate load: not the largest item on your bill, but enough that long daily use is noticeable over a year. It is a good candidate for an efficiency upgrade if your current unit is old.
Over a full year this electric water pump uses about 821.3 kWh of electricity and is responsible for roughly 328.5 kg of CO₂ emissions on an average grid. Because it runs more or less year-round, even a small reduction in daily use carries straight through to a lower annual total.
To put the draw in everyday terms, one hour of running this electric water pump uses about as much electricity as charging a smartphone 63 times. It is a rough comparison, but it makes an abstract wattage figure easier to picture.
If this electric water pump is one you use daily, even small efficiency gains compound. Cutting its usage or wattage by 20% would save around $27.92 every year — money that an efficient replacement can recover over its lifetime.
