Answer:
There are mainly 3 steps which are used to clean the water to supply.
The first is the sedimentation. In this there is a sedimentation tank in which water is kept still for 6-8 hours due to which all heavy particles and dirt settle down. To faster this process, alum is used.
The next step is Filtration. There are different levels of layers, consisting of sand, graphite, charcoal, and pebble rocks. Thus, the water gets filtered by all unwanted particles.
The last step is chlorination. The harmful bacteria are very small to be stopped while filtration, so chlorination kills them and thus water is safe to drink now.
After these 3 steps, the water is transported through various supplies in the town or a city.
So in short, the 3 steps are--->
1) Sedimentation
2) Filtration
3) Chlorination
