Imagine during the times when people only dug wells so that they can get water for drinking and their everyday use. It takes so much time to dig those wells because they needed to be deep so that the water is clean enough to drink. If you have experienced the advantages of Hydraulic Power Units, do you think you will still be encouraged to dig the well manually and wait several days before it finishes? Now, water can be stored in a tank above your house so that saves you space below. Can you do the same with getting that water stored atop your house by carrying the load manually?
