Supplying clean, great-tasting water to your home means we need to make sure our pipes are up to scratch.
We carry out regular checks, cleaning and even replacing pipes in our network to keep the water flowing as it should.
We clean water pipes by increasing the flow of water through them, this is called ‘flushing’. Flushing dislodges any harmless sediment that has built up, removing it from the inside of the pipes.
Of course, sometimes, our efforts mean you may notice a temporary change in your supply, while we work. Our FAQs below will help answer any questions you may have.
By using hydrants in a controlled way, we increase the flow of water through the pipes, but not the pressure. This helps dislodge harmless sediment which is then removed.
Our flushing activities are planned to make sure we're being as efficient as possible with the water used.
This can make your water look orange, brown or black, and is completely normal. It will normally clear if you run the cold tap in your kitchen. You should run your tap for up to 40 minutes or until clear. Don't use your water-reliant appliances, or your hot water supply, until your cold water runs clear.
You might also notice cloudy, or "white" water, which is caused when the water becomes aerated. It is safe to drink and not harmful to health. If you fill a glass with cloudy water and leave it for a minute or so, the bubbles will disappear.
If you’re on a water meter, and we’ve asked you to run your tap for 40 minutes after contacting us, we’ll apply a credit to your bill for the water you’ve used. This covers you for 5,000 litres, which is the equivalent of running your tap for 9 hours.
The pressure will go back to normal once we're finished.
