Describe the various stages of purification of drinking water

Explanation

### Step-by-Step Solution for the Purification of Drinking Water

1. **Source of Water**: The purification process begins with sourcing water, typically from a river or other natural bodies of water. This water often contains various impurities and microorganisms that need to be removed before it is safe for drinking.

2. **Sedimentation**: The sourced water is then transferred to a sedimentation tank. In this stage, the water is allowed to sit undisturbed, which enables suspended impurities (like dirt and debris) to settle at the bottom. This process helps in reducing the turbidity of the water.

3. **Addition of Chemicals**: To enhance the sedimentation process, chemicals such as alum and lime are added to the water. These chemicals help in clumping the impurities together, making it easier for them to settle down quickly.
