Hard water

There’s lots to discover about hard water. When your water travels through our region’s unique chalk streams and rivers it becomes rich in minerals, which is good for you and the environment.

Why do we have hard water?

If you live in the East of England, it’s likely you’ll have hard water. This is because millions of years ago, a warmer climate melted the ice in the North and South Poles. Chalk and limestone formed when parts of the UK were at the bottom of a sea that covered a lot of Europe. Hard water areas like ours get groundwater from chalk or limestone rocks.
