Discoloured Water
Discoloured water occurs occasionally in all water supply systems. It is most commonly caused when there is a sudden increase or change in direction of water flow through pipes. Operational incidents, such as burst water mains, or use of fire hydrants are examples of events that cause this discolourisation.
Harmless deposits of iron and manganese that have accumulated within the water main over a period of time are disturbed and suspended in the water, giving it a discoloured appearance. Although unsightly, the suspended particles are harmless to health and the water is safe to drink.
