My Water is discoloured what can I do?
Discoloured water is usually caused by the disturbance of deposits in the water pipes. The disturbance of deposits can happen when a water main is shut off due to essential maintenance or in an emergency. Our website is constantly updated, click Planned work or Emergency work to find out more.
Discoloured water is unlikely to be harmful to health but we wouldn’t expect anyone to drink it when it looks unpleasant. It usually clears fairly quickly after a few minutes of flushing your taps though but it may take around 45 minutes of running the tap before it clears.
Avoid washing clothes until the water is clear but if you have and the discoloured water has stained your washing, please re-wash when the supply has cleared. If the clothes are still stained after re-washing please keep the stained clothes and contact us on 0800 052 0130
If you are concerned and the discolouration hasn’t cleared, please call us on 0800 052 0130

In the UK there are strict regulations (The Water Supply (Water Quality) Regulations 2010) that require drinking water to meet a set of quality standards to make sure it is both safe to drink and tastes and looks acceptable. We carry out over 300,000 tests every year to monitor the quality of the water we supply to confirm that it meets these standards. We take samples of water as it leaves our treatment works and storage reservoirs and as it reaches our customers’ taps. The Drinking Water Inspectorate continuously monitors our test results to make sure we comply with the water quality standards.
