In this episode of The Water Road, we begin a journey along the Llangollen Canal, and discover why the water flows so strongly. Hurleston Reservoir near Nantwich in Cheshire takes around 40 million litres of water a day from the canal, which brings it nearly fifty miles from North Wales. We speak to Rob Moore from United Utilities, who explains why the water is needed and what happens to it next. And CRT's National Hydrology Manager, Dr Adam Comerford, tells us about how water transfer schemes could be expanded to other parts of the canal network.
