Across the northeast we have huge rest of us, but you wouldn't want to drink straight from one. To make sure an authentic submarine water is clean, great tasting and delivered straight to your tap, we wear a card, treating millions of litres of water every day. But we're all using more than ever before. However, by making small changes, like having a short shower instead of a bath, not washing your car as often, or by dropping your hosepipe in letting nature do its job, they'll be plenty to go around. You using water wisely makes a big difference. You're all water's worth saving.
