A hydraulic ram pump is a water pump powered by water. 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, by using the energy in the speed of the flow to pump a portion of the water up to a much higher level.

A hydraulic ram pump is powered by a body of water flowing downhill with a height difference. To pump a reasonable amount of water uphill to another location 200 metres away using the pump requires a 7-10 metre difference. When assessing suitability it is also important to differentiate between the actual height difference and the distance measured along the slope.
