Click to view map Coordinates: | Woodhead Reservoir gets its name from the mayor who laid the last stone on the first of May 1897, Sir John Woodhead J.P. The summit plateau of Table Mountain, with an average rainfall of 1600mm, is an ideal water catchment, and the Back Table contains five reservoirs including this one. The others being Hely-Hutchinson, Victoria, Alexandra and De Villiers. The five reservoirs have a combined capacity of 2273m litres. For a long time these were the city's main sources of water. Some of the water is carried down Table Mountain by means of two tunnels, the Woodhead and Apostles tunnels, 1313 metres in length through Wood Buttress, to a filtration plant above Kloof Nek. During the same period, the last decade of the 19th century, saw the establishment of the Tokai plantations and the commencement of tree-planting on a large scale on Table Mountain and Devil's Peak. At the time of completion the Woodhead and Hely-Hutchinson reservoirs were considered engineering triumphs. The dam was designated as an International Historic Civil Engineering Landmark by the American Society of Civil Engineers (ASCE) in 2008. It is one of two such declared landmark structures in South Africa, the other being the Cape Agulhas Lighthouse. To qualify for inclusion, a project must be over 50 years old, must have made a significant impact on civil engineering in its region, must still be in operation, and adhere to very stringent selection criteria.
