Flood Alleviation Success in Carlisle
27 August 2008, News release from Atkins
Three years since the devastating flooding that struck Carlisle, the £13M Eden and Petteril Flood Alleviation Scheme has been completed ahead of schedule.
The floods in Carlisle led to two deaths and around £500M of losses. Atkins has been working in partnership with the Environment Agency and contractor Volker Stevin to develop and implement a solution to prevent future flooding losses.
The scheme mainly involved raising and replacing flood defence embankments and walls, flood storage and pumping. The project also included environmental enhancements along a 4.5km frontage of both the River Eden and Petteril in central Carlisle.
Part of the project involved raising a structurally substandard 3.5m high Victorian masonry wall by over 1m to achieve the required level of flood defence. Traditional options that would essentially require demolition and reconstruction of the wall were discounted in favour of an innovative piling technique. This technique improves the stability of the existing wall and provides a pile cap to support the new flood defence wall.
The solution provides a highly cost effective, environmentally sound and sustainable solution bringing additional health and safety benefits. Working in collaboration and exploring innovative solutions has resulted in an overall saving of £3M on a scheme that protects around 1500 properties. It also helped the Environment Agency exceed its sustainability targets.
