There are 3 main processes undertaken in the water purifying process:
- Filtration
- Bacterial Oxidation
- Chlorine Treatment
The different stages are listed in more detail below:
- Water pumped from river into a reservoir
- Water fed into sedimentation tank where solids settle
- Sand beds filter out smaller particles
- Chlorine added to water to kill germs
- Sulphur Dioxide then removes the chlorine
- Possibly, water is filtered through GAC (Granular Activated Carbon). This improves the taste and smell of the water
- Possibly, fluorides added to water
- Water is then pumped to its users
