The plastic tank has the shape of parallelogram, which has an angle of 45 DEG on both sides (F and G). The flooded water is withdrawn from the riversides or from the roads into the main plastic tank (E) using the water pump (A.B). After the main tank is filled, its top edge (X) leans on the lower edge of the other tank beside it and stick rigidly with it which will make a strong fence or wall of hundreds of tank (filled with the flooded water) preventing the water from going over the riversides and into the roads. There is a connection between the main tank (which is connected to the water pump) and the other tanks lying head to tail (using the connecting hose H), so that they are filled with water one after one by using only one water pump.
