What should I do if my water is discoloured/cloudy?

We continually test the water we supply to our customers to ensure it is safe.

However, during its journey to your taps there are a number of ways in which the appearance of your water can be affected and occasionally it can become discoloured.

The most common cause of discolouration is a change in the flow or pressure within the pipes, for example when there has been a burst water main.

The change in pressure can dislodge tiny deposits such as iron or manganese, which may turn the water brown for a short period.

Please be reassured that neither iron or manganese are harmful to health at the levels found within tap water.

Your water may also appear cloudy, or white, on occasion. This is usually nothing more than air bubbles which may enter your water due to a fault in your plumbing. Again, this is not harmful and the bubbles will disappear if the water is left to stand.
