1
Raw Water Intake: Water is collected from underground sources (aquifer) or surface water sources (rivers/lakes)
↓
2
Pre-filtration: Large particles, sediment, and debris are removed using screens and sand filters
↓
3
Coagulation & Flocculation: Chemical coagulants are added to clump small particles together, forming larger aggregates that settle easily
↓
4
Sedimentation: Water is left to settle in tanks, allowing heavy particles to sink to the bottom where they are removed
↓
5
Filtration: Water passes through layers of sand, gravel, and activated charcoal filters to remove remaining particles and improve clarity
↓
6
Disinfection: Chlorine or UV light is applied to kill bacteria, viruses, and other harmful microorganisms
↓
7
pH Adjustment: Lime or other chemicals are added to adjust the pH level to the appropriate range for safe consumption
↓
8
Storage & Distribution: Purified water is stored in large reservoirs and distributed through pipes to homes and businesses
