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.
