The hydraulic ram pump - which has been around for a couple of centuries. falls into this category. The Alternative Indigenous Development Foundation Inc. (AIDFI) is determined to see the ram pump finally come into its own. Using the power of a river's flow to literally push water uphill without any other energy input, it's proving to be a boon for poor villagers living in mountainous regions.
The ram pump can save both hours of back-breaking work carrying water and cash where expensive water pumps are replaced. AIDFI has introduced the ram pump to over 170 upland villages, and has plans to spread the benefits far and wide among poor communities.
