Dwr Cymru Welsh Water
My Wastewater Service Sewage Pollution

Dŵr Cymru Welsh Water works to protect rivers and other waterways by treating the wastewater from our homes and businesses and safely returning it to the environment. It requires huge amounts of equipment and thousands of kilometers of sewers.

We must ensure that they operate effectively. If something goes wrong, then sewage pollution of watercourses can have a major impact on wildlife and amenity value.

We’re working hard to minimise such pollution, and we’d like your help. You can do it by telling us as soon as possible if you see sewage pollution in a river, stream or other watercourse.

Help keep our rivers clean
