Cleaning local water mains

We clean local water mains to remove the natural sediments that can build up over time. By flushing the mains as part of a regular maintenance programme, we can ensure we continue to provide you - and your neighbours, with high quality drinking water for many years to come.


How will this affect me?

To minimise any disruption to you, we carry out this work overnight. We'll let you know before it takes place.

  • As this work is being completed, you may notice your water becomes slightly discoloured or cloudy. This is temporary and your water is still safe to drink. Running your taps for a few minutes will help to clear it.
  • You may experience lower water pressure. To prevent any interruptions to your appliances, we suggest you do not run your washing machines or dishwashers during the time we plan to carry out the work. Your central heating system won't be affected.
  • Some areas in the road and footpaths may be coned off for safety. While we carry out this essential work our teams will be following the latest government guidance, we ask that this is respected for your safety and ours.
  • If my water supply is discoloured is it safe to use my appliances?

    Washing machines and dishwashers should only be used if your water supply is running clear. This is to prevent any staining.

  • Will any precautions be taken due to Coronavirus?

    Yes. Our teams will work safely and within government guidelines to make sure that we continue to provide you with high-quality, reliable drinking water, and that you can still receive the service you expect from us. We have developed robust risk assessments for our work activities and adapted our ways of working as we’ve learned more about the virus.

    We are extremely proud of the work our colleagues do and their commitment at this time and ask that you help us in respecting social distancing.

  • Will my water pressure be affected?

    Some customers may experience a change in their water pressure, but it will only be temporary. We run our mains cleaning programme at night , between 10pm and 6am to minimise any disruption to you.

  • How can you help someone who needs special assistance?

    The Priority Services Register (PSR) is free to join. We don't expect you'll be without water, but it helps us to know who may require extra help in the unlikely event that your water supply is interrupted. So if you have additional physical or mental health needs or are registered as Clinically Vulnerable please register here.

  • Will I be notified if my water supply will be turned off?

    We will notify you of any planned interruptions to your water supply.

  • How can you help someone who needs special assistance?

    We have a database of customers who have specific water requirements, if you are concerned please contact us on 0800 521 660, and we will make arrangements to help you.

  • How much water is used?

    We are committed to using the least amount of water possible to clean the mains. We calculate the precise volume of water required for each and every section of pipe work. This ensures that we always use the least amount of water possible to achieve correct amount of cleaning.
