The technical brief contains the detailed information on hydraulic ram pumps that can be used by communities around the world allowing access to water where the source of water is lower than the compound. It contains technical knowledge on building a self-powered water pump that can be operated locally with minimum cost. Communities in various parts of the world are situated in the height from the spring that does not allow water to flow to compounds by gravity, hence hydraulic ram pumps be an appropriate solution to lift the water from the sources to their compound. These water powered ram pumps can work without the use of electricity and has low maintenance cost making it suitable for developing countries.
