Ever seen water flow uphill? Without help of petrol or electricity? Meet the hydraulic ram, a robust and simple water-powered water pump. The ram pumps uses the power of water with a height difference flowing in the spring, stream or river to lift a fraction of the water up to 200 metres vertically, and sometimes pump it over a kilometre or two to where it is needed. No fuel or electricity required. The ram pump holds great potential for rural drinking water and irrigation water supply in hilly and mountainous areas, such as Afghanistan, Colombia, Nepal, and the Philippines.

====Akvo projects with Ram Pumps====
Akvo has a number of projects with ram pumps in its system. You can support [http://www.akvo.org/rsr/project/95/ this project on bringing hydraulic ram pumps to upland communities in the Philippines], or [http://wwwrsr.akvo.org/rsr/project/75/ this project on transferring hydraulic ram technology to Colombia].
