This movie shows how EMAS handpumps can be used in a well near the home, and how water can be pumped over a distance.

This movie shows how to make a windmill which powers an EMAS pump.

This movie describes how to make a hydraulic ram. A hydraulic ram pump is a water pump powered by water with a height difference.

In areas where natural flows exist with a height difference of the water over a small distance, hydraulic ram pumps can be used to transport water to higher grounds without using electricity or fuel.
