Hi,

I have constructed 75000 L underground RCC water tank. The tank depth is 12 feet. I want to install a mono-block pump inside the house. The distance of the pump from the water tank is 100 Feet. I want to fill up an overhead tank of 1000L capacity which is located at a height of 30 feet. Need to know if a mono-block pump can have suction of 100 feet length. What capacity (HP)  pump will I require to pump water from the underground tank to fill the overhead tank. Please guide me.
