It is also the object of the present invention to preserve and store the sweet water, from the coastal region during the rainfall which otherwise discharging to the Sea, for productive use i.e. to be used at low rainfall level. It is also the object of the present invention to reduce "flash flooding" in urban areas and store surplus flash flood water in multistoried tanks. According to present invention, a system for pumping water consisting of two tanks as one unit, connected by two pipes, one intake and the other one is an exhaust pipe, each tank of approximately 25 feet height having lateral dimensions depending upon the volume of water to be pumped. Intake port is fitted at the base tank from where the water is to be pumped and each of the tank having a float or water level detector and an exhaust fan is fitted in-between two tanks (i.e. at least one exhaust fan for one unit) for creating negative pressure inside the tanks.

Now referring to the figure 1, the suction pumping of water by creating negative air pressure associated with sequential valves and exhaust fan operation comprises, tanks i.e. base tank (1) and upper tank (2) with flexible shapes having three two way or six one way sequential valves in each unit i.e. two tanks (tank 1 and tank 2). At the intake port (3) the valve V2 is fitted to the base tank from which water is to be pumped. The exhaust fan (4) where the valve Vl is fitted, is attached in between two tanks for the suction of the air from the tank, third valve V3 is fitted on the intake pipe of upper tank. Water level detector (5) is provided in each tank so that by sensing the water level, the sequential opening and closing of the valves can be done. Water is sucked up through intake port alter creating the negative pressure inside the tank using the exhaust fan and fills the base tank or first tank and when desired level is reached, then water level detector in the said tank shuts valve V2 in position A and opens position B, simultaneously Vl shuts in position A and opens position B for suction of air from the second tank or upper tank.
