I hope everyone realizes that EMP would not be just a one time event. Every time a nuke goes off it makes EMP. The higher above ground the nuke is set off the farther the EMP burst travels. The closer you are to ground zero even with a ground burst the more EMP you get. The longer the wires are that your equipment is hooked up to the higher the EMP voltage it receives is.

Water cannot be pulled up anymore that 25 feet. But water can be pushed up hundreds of feet. It is a law of physics.

A regular deep well pump has an outer pipe called the casing and inside the casing is a smaller diameter pipe with and electric motor water pump at the bottom of the pipe.

A good purely mechanical means of getting water from a deep well is to blow air down the well casing through a hose or a pipe. The air pressure will push the water our the top of the well casing. A large air compressor with an electric motor can be used instead of an electric pump motor at the bottom of the well.

With no electricity to run the well air compressor it could be geared to be cranked by hand.

I have seen and worked on this kind of air compressor well water drawing method. It is used in areas where sand keeps plugging an electric well pump at the bottom of the well. So they remove the electric well pump at the bottom of the well and use compressed air to bubble water up the casing instead.

This air compressor method is also used with an air hose to test newly drilled water wells to save the expense of the inner pipe, electric pump motor, and the wires to the motor in case there is no water in the well.
