1. Coagulation: Alum and other chemicals are added to water to form tiny sticky particles called "floc" which attract the dirt particles.
2. Sedimentation: The heavy particles (floc) settle to the bottom and clear water moves to filtration.
3. Filtration: The water passes through filters that help to remove even smaller particles.
4. Disinfection: A small amount of chlorine is added to kill any bacteria or microorganisms that may be in the water.
5. Storage: Water is placed in a closed tank or reservoir where it flows through pipes to homes and businesses in the community.
