Appropriate Technology - The Hydraulic Ram Water Pump

In many areas of the World, the access to clean drinking water is the most vital thing in terms of peoples' health. This often means having to draw up water from underground & even where there is no electricity, this can be done using an undrinkable source of water as power. The hydraulic ram pump is a simple but clever piece of technology that uses a relatively large flow of surface water to pump a smaller amount up from below. It needs no other power source, runs constantly & is virtually maintenance free - important qualities that enable it to be used effectively in many countries around the World.
