Discolouration
The water we supply is clean, fresh and of high quality but during its journey from our works to your taps it can be affected by a number of factors.
Most complaints about discoloured water are due to a change in the flow or pressure in water pipes, such as a burst main, which dislodges tiny deposits such as iron or manganese. This can temporarily turn the water brown, although it is not harmful to health. If we are working on our mains and think this may happen we take measures such as flushing the pipe to minimise the risk of discolouration.
Drinking water which appears cloudy or white is usually caused by air bubbles, which are harmless and will disappear if the water is left to stand. This can be caused by air entering your domestic plumbing through a fault.
