1.Dosing- Is when they add chemicals to remove some dirt and bactreria.

2.Clarify- When impurities settle to the bottom so that they can be removed from the water.

3.Filtration- When the water is filtered through different filters (eg: sand filter) to clean the water.

4. Disenfection- When the water is disinfected so that it is safe to drink (using chlorine or other methods).
