History In 1852, the East London Waterworks Company (ELWC) was granted permission to develop land at Walthamstow for reservoirs and by 1863, the first stage of the reservoirs’ development was completed with the construction of Reservoir Nos. 1, 2 and 3. In 1897, Lockwood was the last reservoir to be created and also the largest – covering 30 hectares and excavated to a depth of around 8 metres. Named after one of the ELWC’s directors, it was a major engineering feat for its day - requiring a huge labour force of 1,250 men. Unlike the first reservoirs, which were dug mainly by hand, Lockwood was constructed with plenty of steam-powered pumps, engines and cranes - as well as a team of 50 horses! The ELWC was taken over by the Metropolitan Water Board in 1904.Lockwood Reservoir Retrieved 16 November 2007
