Solution

The purification of water involves a series of steps before it is ready to be supplied for drinking purposes.
The first step involves the water to be stored in a sedimentation tank where all the suspended matter settles down.
The next step involves the filtration process in which all the sediments are filtered out.
Then water from the filtration tank is warmed up to carry out the process of distillation in which all the volatile impurities are removed.
In the final step, water is moved to a chlorination tank in which chlorine tablets are used to disinfect the water from bacteria and other micro-organisms.
Now the water is ready to be supplied for drinking purposes.
