About Welsh Water


Although it falls freely from the sky, we put a lot of work and energy into getting every drop of water to our customers.

After it’s used, we take the dirty water away and clean it before returning it to our beautiful rivers and seas.

This is why we have sites and pipes in every community we serve – from the water treatment works high up in the Snowdonia Mountains to the wastewater treatment works dotted along our coast.

At Welsh Water we are different from other water and energy companies. We don’t have shareholders. This means that we’re able to keep bills down, help more customers who are struggling to pay their bills and also put every penny we make straight back into maintaining and improving our service and protecting our environment, now, and for years to come.

We serve over three million people in most of Wales Herefordshire and parts of Deeside.
