How do we treat the water?

slide-15
SLIDE 15

Screening

Removes large items like fish, sticks and leaves

slide-16
SLIDE 16

Flocculation

Coagulants are added to the water and bind fine particles together into larger particles called ‘flocs’

slide-17
SLIDE 17

Filtration

Sand and gravel filters are used to remove the final particles

slide-18
SLIDE 18

Disinfection

Disease carrying micro-organisms which are too small for the eye to see are killed
