Ram pump

The purpose of this tutorial is to facilitate the understanding, design, manufacture and installation of a water elevation system called "Ram pump". This technology was documented during a stopover of the Sea Nomad in the Philippines, on the island of Negros. The NGO "Alternative Indigenous Development Foundation (AIFDI)", based in the city of Bacolod since 1991, helps more than 160 rural communities meet their water needs by installing hydraulic rams throughout the archipelago. The ram pump presented in this tutorial is a different version from the one used by the AIFDI because it is more accessible.
