The Leigh Barrier was built in 1980 as an impounding reservoir to hold back floodwater during storms and thus provide some flood protection for Tonbridge and some other towns on the River Medway. The barrier consists of 1.3 km of bunded wall encompassing 300 hectares. The reservoir is a class one structure under the Reservoirs Act meaning that it's failure would result in loss of life.
During the year 2000 floods the barrier was instrumental in protecting many thousands of homes from the worst effects of the storms.
In 2002, the Environment Agency commissioned Babtie Brown and Root to survey the barrier and recommend refurbishment options. Kenneth Grubb Associates Ltd (KGAL) was appointed to undertake the Mechanical and Electrical part of this work on the Radial gates and operating machinery.
KGAL undertook a series of surveys, including some intrusive equipment strip down work. A series of issues was identified leading to the development of a number of alternative control and machinery options. A report was delivered to the Agency in 2002.
In 2003 the Agency again appointed BBR and KGAL to develop the options identified with a view to implementing them.
