Water treatment

This is the process where dispersed insoluble particles in raw water come out of solution to form larger particles known as floc.

This process removes particles from raw water. This may be via sedimentation assisted by gravity, or dissolved air flotation whereby tiny air bubbles separate the particles.

This process utilises granular media filters to remove the particles, or floc resulting in clear water.

Disinfection removes, deactivates or kills microorganisms in the water. This typically involves dosing chlorine or ultraviolet irradiation.

Fluoride is added in some of our water supplies at the direction of the Department of Health and Human Services for oral health. Check if your water supply is fluoridated here.
