From raw water to the tap, in six stages
Every plant is a sequence of barriers. Follow the flow — each stage links to the guides that explain it.
-
01
Intake & Screening
Raw water enters; bar screens and grit channels remove debris.
-
02
Coagulation
Coagulants destabilise fine particles into settleable floc.
-
03
Sedimentation
Floc settles out under gravity in clarifiers.
-
04
Filtration
Rapid sand and media beds polish the remaining turbidity.
-
05
Disinfection
Chlorine, UV or ozone inactivate the remaining pathogens.
-
06
Distribution
Treated water is pumped to storage and the network.
