Water well pump electrical requirements.

You see to get free water from the well you must provide some sort of electrical service. However when it comes to water supply safety and ground water protection most water well related work is best left to professionals. If there s no power on site you need to spec a generator. Take the wattage of the specific water pump and multiply it times how many hours a day it runs.

There is a calculation to find the power consumption of a water pump. Friction loss in piping and efficiency 1 0 can be calculated as. You ll need 1 5kw per motor hp so a 5hp pump needs a minimum of 7 5kw you also need to spec the right power cable pvc flat jacketed wire is the most common. Most submersible pumps with 5hp or less are 230v single phase.

Then multiply it by how many days a year it runs and divide by 1000. The 240 volt pump circuit to your well pump does not have a neutral so you cannot get 120 volts without doing something that would be unsafe. Well regulationsthis article written by the american ground water trust was originally published in the american well owner 2001 number 3 regulations relating to home well constructiondo it yourself is a good maxim for self reliance.
