 During the assembly of the new water treatment facilities, both the Mugdock and Craigmaddie reservoirs were drained in 2005 and 2006 respectively to facilitate the laying of pipes to and from the plant, and the resultant scene from Craigmaddie reservoir can be seen above.Special consideration had to be taken for the draining of the reservoirs, as they had never been drained in 150 years of operation.Mugdock reservoir was initially built and opened in the 1850s.
