It is not scientifically worked out, but it works and is about as efficient as a commercial pump, and it takes the elbow grease out of pumping by hand or the expense and complications of an electric pump. However, the principle also works on a smaller scale, and I have made a pump from standard brass 28 mm compression fittings, with 28mm, 22 mm and 15 mm pipe (all readily available) and with soldering equipment. The pumps featured in the books do require welding and threading equipment, and the smallest pump has a 2" diameter body which requires a fair amount of water to operate.

They also explain how to design and build the whole system. I would recommend you get both they do complement each other. The other is "A Manual on the Hydraulic Ram for Pumping Water" by S. One is "Hydraulic Ram Pumps: A Guide to Ram Pump Water Supply Systems" by T.D. There are two excellent books published by Intermediate Technology on making your own ram pump. If the cost of a commercial pump puts you off, or the water volume is too little to operate the pump, you can make one to suit your conditions at very little cost. Hydraulic ram pumps are powered by a portion of the water running through it. If you have a water supply (spring, brook or river) below the point where you need the water, and the source is higher than the lowest part of the property, then a hydraulic ram pump may be the solution.
