After an incident


Following an incident, you may have some questions about your water supply returning or what happens next if you need to make a claim.

Help and Advice

Your supply may look different to normal for a short period of time after an incident.

Discoloured water

Discoloured water which is yellow, orange, brown cloudy or black is caused by particles of iron or manganese, which have usually come from cast iron water mains, and have settled over time in the network.

As we return water through the system and the pressure increases, this can increase the water flow and can stir up the sediment.

Discolouration is usually short term and if you run your taps for a few minutes then this should clear.

Cloudy Water

Tiny air bubbles can cause your water to look cloudy or discoloured. The air bubbles are quite harmless and will quickly clear.

If this happens, try leaving it in a glass of water for a few minutes to see if it clears.

Cloudy Water is usually short term and if you run your taps for a few minutes then this should clear.

Frequently asked questions

Low water pressure

Sometimes the water pressure can take a while to build up again following an incident.

The pressure might take several hours to fully return and depends on where you live. For example, customers at the top of a hill are likely to take longer to get full pressure than those at the bottom.

The water might also splutter out of your taps when it first comes back on. This should clear if you run your taps for a couple of minutes.
