How to make a hydraulic ram pump which requires no electricity and no motor.This pump uses falling water to lift a lesser amount of water to a higher elevation than the source. So, being primarily used for lifting relatively small amount of water to a higher elevation. If you want to deliver 2 cubic meter of water to an elevated location, you need at least 6 cubic meters of water to operate the pump 4 cubic meters of which will be used to drive the pump and goes directly as waste.
This video shows how to build a simple water pump that needs no energy input other than water flowing from a higher point to a lower point.Most of the pump is constructed from PVC, with a couple of bronze pieces thrown in for flavor, you can find all of the parts from a local hardware store (Lowes) for a bit under $100. The hydraulic ram is sometimes used in remote areas, where there is both a source of low-head hydropower and a need for pumping water to a destination higher in elevation than the source. In this situation, the ram is often useful.
