- Water Quality
- Rivers and groundwater enter reservoirs
- Water passes through filter made out of fine sand to remove any remaining particles of mud/grit
- Passes through mesh screen to remove leaves/twigs
- Aluminium sulfate and limme added to water. Small particles of dirt stick together and sink to bottom - landfill site as mud
- Water filtered through gravel beds to remove all solids
- Chlorine added to kill bacteria
- pH checked if neutral - good
- Chlorine added to kill bacteria
- Water filtered through gravel beds to remove all solids
- Aluminium sulfate and limme added to water. Small particles of dirt stick together and sink to bottom - landfill site as mud
- Passes through mesh screen to remove leaves/twigs
- Water passes through filter made out of fine sand to remove any remaining particles of mud/grit
- Filter Jugs
- Contain activated carbon- reduces levels of chlorine
- Ion - exchange resin - removes metal ions
- Silver - discourage growth of bacteria in filter
- Distillation
- Boil water - turns into gas - steam - condense - collect = pure water
- Need a lot of energy - expensive
