The image presents a flow diagram titled "How drinking water is collected, treated and supplied to homes," organized into 8 numbered stages connected by arrows. Stage 1, labeled "Reservoir," describes "raw water collected from rivers and rainfall." Stage 2, labeled "Screening," details "metal screens remove large debris such as leaves and branches." Stage 3, labeled "Coagulation tank," notes "chemicals added; small particles clump together." Stage 4, labeled "Sedimentation tank," states "heavy clumps sink to the bottom" and includes a downward arrow leading to a box labeled "sludge removed for disposal." Stage 5, labeled "Filtration," indicates "water passes through layers of sand and gravel." Stage 6, labeled "Disinfection," specifies "chlorine added to kill bacteria." Stage 7, labeled "Storage tank," denotes "clean water stored." Stage 8, labeled "Homes," concludes with "water pumped through underground pipes to houses."
Given the complexity of the image, the above description may not be entirely accurate.

The provided diagram illustrate that how to the water collected from river or rain water converted into a drinking water by some mechanical and chemical methods .
First of all , this process holds main four methods firstly collect the water and then refining the impurities and after that store in big tanks and then supply in living areas .
To commence with , this process holds eight distinct methods firstly collect the water from river or rain water .
After that water is passed from metal screens in which the large debris such as leaves , branches and another waste are refined . then water then sent to congulation tank in which added some chemicals and mixed to refine impurities and then sent in sendimentation tank in which sand is refined .
moreover , now the turn of filtration the water passed through layer of sand and gravel to filter . after that the disinfection is held in which to kill bacteria the chlorine is added and then water is stored in large tank . lastly it supplies to living areas as a drinking water .
