History

Part of the Elan Valley reservoir scheme built by City of Birmingham 1893 to 1904. Engineer James Mansergh. The scheme was amongst the greatest civic achievements of the late C19. The Corporation of Birmingham employed direct labour for the scheme which involved the construction of 53 km of railway to transport materials from the Wye Valley line at Rhayader, 4 dams, an aqueduct 126 km long, and a village for construction workers. The height of the reservoirs enabled water to reach the outskirts of Birmingham by gravity alone, without the expense of pumping. Provision was made for future expansion in the Claerwen Valley where the scheme was brought to its current state by the Claerwen dam in 1952. Water supply to Birmingham is taken from this tower.
