Wonderful on tap
We think water’s wonderful. It plays a critical role in all our lives.
It’s the shower that wakes us up, the hot bath that relaxes us before bed. We cook with it… grow gardens with it… have fun with it. Oh yes, and it keeps us alive!
Whether it’s supporting local businesses, offering a great day out at our reservoir sites or investing in the young people in our region, we've an important role to play.
How we’re dealing with the risks posed by climate change, pressure on water supplies, switching to greener energy and improving biodiversity.
Our Social Purpose
At Hafren Dyfrdwy, we believe that being a socially purposeful company is a core principle.
We are a company guided by a clear public service ethos that also draws on the benefits of private sector investment to improve services.
We seek to give our customers the best of both worlds.
