The Colwick Sluice in Nottingham is a key component of the flood defence apparatus designed to protect the city; one that the Environment Agency (EA) has been upgrading in order to improve the efficiency of essential maintenance work. As part of this project ECS Engineering Services has installed a new semi-automated stoplog deployment system that provides the EA with 'dry' access to the sluice gate mechanism, speeding up operations considerably. Originally built in 1955, the Colwick sluice consists of five sluice gates and forms a key control point for the water levels of the River Trent and is used by the EA to protect Nottingham against flooding. The last major work to be carried out at Colwick was in 1995, when the sluice gates were replaced and fresh concrete was laid in the base to alleviate river bed erosion on the downstream section of the river.
