Dwr Cymru Welsh Water

Monday, 17th February

With flooding still affecting many communities in Wales and Herefordshire, we are experiencing high volumes of calls due to the high winds and heavy rain and our crews are extremely busy.

Here are the organisations you may need to contact:

Natural Resources Wales - 0800 80 70 60 (24 Hours) - if the flooding is coming from a watercourse (such as a stream) that is about to or has burst its banks.

Your Local Council – if you suspect the flooding is resulting from rising groundwater or surface water run off.

Welsh Water Sewerage Services & Emergencies - 0800 085 3968 (24 hours) or report an issue via a webform – for flooding inside your property caused by a blocked or overloaded sewer.

How to Report Sewage Pollution

If you see sewage pollution please call our hotline as soon as possible on 0800 085 3968. Our Operational Call Centre is open 24 hours a day, every day of the year. Calls are FREE from a BT landline.

What we will ask you:

  • What have you seen, and when?
  • Where did you see it?  (Is it near a landmark?) 
  • Is sewage still entering the watercourse?
  • What are the weather conditions?

What we’ll do:

  • Take immediate action. All sewage pollution incidents are a high priority and we aim to be on site within two hours.
  • Tell Natural Resources Wales immediately, as it looks after rivers in Wales and England

If our sewers are responsible we will:

  • Stop the pollution as soon as we can
  • Clean up the watercourse and any other affected areas
  • Investigate the causes of the pollution incident to prevent any recurrence

Dŵr Cymru Welsh Water is investing more than £12.5 million between 2010 and 2015 to reduce the number of sewage pollution incidents to watercourses caused by our assets.
