The picture illustrates the process of producing fresh water. Overall, it is a man-made and natural process, and it takes 10 stages and a short time. This process begins with collecting water in the reservoir and ends with the distribution of treated water to consumers. Firstly, water is collected naturally, such as rainfall and snowmelt, and sent to pumps via intake screens. Water is mixed with chemicals, where elements such as polyaluminium chloride and oxidants are added to remove impurities. Once flocculated, water is transported to the large settling basin. The next stage begins with the addition of chlorine to the water, and it is cleared in the filter membrane. When water has arrived at the disinfection stage, it is mixed with several elements. In the final phase, the treated water is pumped through a distribution system and supplied to schools, residential areas, and the countryside through taps.
