The Elan aqueduct crosses Wales and the Midlands of England, running eastwards from the Elan Valley Reservoirs in Mid Wales to Birmingham's Frankley Reservoir, carrying drinking water for Birmingham.[1]
It delivers enormous quantities of water by gravity across the mid-Wales countryside, through north Herefordshire, south Shropshire and into the West Midlands through eleven major river valleys. The aqueduct is 73 miles (117 km) long, down which the water travels at less than two miles per hour (3 km/h), taking one and a half days to get to Birmingham.
