My water is yellow, blue or green in colour

Straw-coloured or yellow water can be caused by the disturbance of naturally occurring sediment in the supply, or particles from corroding, unlined iron pipes.

This disturbance is caused by a sudden change in the direction or flow rate of water. This can occur due to a burst pipe, work being carried out on pipes nearby, or through an increase in demand such as when the fire service connect to our mains or someone illegally uses a hydrant.
