A hydraulic ram pump is powered by a body of water flowing downhill with a height difference. To A general rule of thumb is that the water can be pumped 30 times as high as the available drive head (the height difference of the water driving the pump ). So a reasonable amount head of 1 m can be used to pump up water uphill to another location 200 metres away using the pump requires ~30m, while a 7-10 metre differencem head can pump water up to 210 m. When assessing suitability it  The capacity of a hydraulic ram depends on the scale of the pump, which is also important often measured in the diameter of the tube delivering the water to differentiate between the pump. Pumps exist in the range 1" up to 5".  With height difference, the actual difference in vertical height difference and is meant, '''not''' the distance length measured along the slope.
