A hydraulic ram, or hydram, is a cyclic water pump powered by hydropower. It takes in water at one "hydraulic head" (pressure) and flow rate, and outputs water at a higher hydraulic head and lower flow rate. The device uses the water hammer effect to develop pressure that allows a portion of the input water that powers the pump to be lifted to a point higher than where the water originally started.

These ram pumps, capable of pumping water up to 200 metres high, are bringing clean water to people who previously had to undertake often difficult and dangerous journeys just in order to collect clean water. It can be used for washing, sanitation and irrigating crops.

There is a huge need for this type of technology in areas where there is no immediate access to clean running water. Best alternative water system for the people of Garcia-Hernandez who are experiencing water shortage on their homes.
