Experiencing brown or black discoloured Water?

Discoloured water is normally short lived and can often be cleared by allowing the first incoming cold water tap to run for five minutes.

Please select from the glasses below to find out more details about your discoloured water:

Discoloured Water: Dark brown/black

Dark brown or black coloured water is normally short lived and can often be cleared by allowing the first incoming cold water tap to run for five minutes.

If you experience short term discoloured water and you need water for drinking or cooking, please follow this advice:

  1. Run the first incoming cold water tap for several minutes (this will usually be your kitchen tap)
  2. Fill a jug and leave it to stand until any sediment has settled to the bottom
  3. Pour the clean water from the top of the jug for you to use

You can also check what is happening in your area by entering a postcode below to see if we are already aware of any issues with the supply.

If running the tap does not clear the discolouration, please check with your neighbours to determine if their water is also discoloured.

If your neighbours do not have discoloured water then the cause is almost certainly due to pipework between the main in the road and the kitchen tap.  It may be worthwhile checking whether you have any lead pipes in your home. For more advice click here.

Dark brown or black coloured water is usually caused by naturally occurring iron and manganese deposits which settle in the water mains over time. Normally these deposits don’t affect anyone, but can on occasion be disturbed and re-suspended into the water resulting in discolouration. This can occur during a sudden change in the direction or flow rate of water within the mains, such as when there is a burst or through an increase in demand; for example when the fire service connect to the mains network.

While your tap water is discoloured, don’t run the hot water tap or use dishwashers, washing machines or any appliances fed by your hot water supply.

In our experience, discoloured water caused by main deposits is unlikely to be harmful to health.

What are Yorkshire Water doing to reduce the likelihood of discoloured water?

Yorkshire Water has over 31,000 km of mains in the ground and supplies water to almost five million people in the Yorkshire region. The Company has a process to prioritise where mains rehabilitation or cleaning/flushing may be required.

In areas where there is localised historic discolouration, Yorkshire Water operates a programme to flush clean the water mains. Flushing is a proactive and controlled way of removing the sediment which causes discoloured water and therefore reducing the likelihood of it occurring in the future.

We will always let you know when this activity is being carried out in your area. For more information please view our pipe cleaning video.

The quality of water leaving the water treatment works continues to improve with more effective removal of naturally occurring iron and manganese from the water. Yorkshire Water will continue to replace cast iron mains and will continue to clean many of our large diameter trunk mains where mains deposits are known to be an issue.
