Water is the source of life and one of the most valuable treasures of man. Water depends not only on a normal life, but also on the very existence of mankind. It is no accident that since ancient times people have settled on the banks of rivers and lakes, trying to build their homes as close to the water as possible. Nothing can exist without water, be it the rare droplets that irrigate the desert, or the heavy rainfall, the murmuring streams or the peaceful river streams, the light sea breeze or the crushing ocean waves.
