Hydraulic Ram Pumps are very old technology that pump water using gravity and 2 valves to generate a repeating water hammer effect. The "hammer" pounds a little of the drive water into a pressure tank then up the delivery hose for your use. Why is it green? Because it's simple, reliable, pumps water without any engine, fuel or electricity or muscle power and can be made from mostly recycled materials.

The one I built has a few novelties that make it more reliable, cheaper and easier to operate than most of the plans you find on the Internet. It developed a steady 28psi pressure at the pump and delivered about 1,000 gallons per day where we wanted it.

last season, it hammered over 145,600 gallons of pond water up a steep hill to our garden over 700 feet away and over 100 feet higher than the pond! In the process, it saved us over 485 liters of diesel fuel we would have normally used to drive our diesel tractor to pump and tow the water around our farm.

The pump was built for about $50 worth of plumbing parts and a bunch of stuff that I had sitting in my scrap pile.

What's the secret? A strong gate valve - period.
