Flood alleviation works valued at £75,000 in Thurstonfield, near Carlisle have been completed by Cumbria County Council.
The council’s Lead Local Flood Authority project team successfully bid for funding from DEFRA and the Environment Agency’s Flood and Coastal Erosion Risk Management (FCERM) Grant in Aid fund, to deliver the scheme, which reduces the risk of flooding in the village.
The village has a history of regular flooding events, the result of a dilapidated surface water drainage network. New housing developments over subsequent years have added pressure to the network with a significant silt build up, blockages and collapses. Surcharging water inundates local drainage infrastructure and results in flooding to nearby properties and highway.
The final scheme design consisted of repairing and replacing the extensively damaged sections of culvert, adding further manholes to assist with future access and maintenance, and lining almost 200m of culvert – lining is a repair technique which renews the pipe without the need for excavation, and will prevent tree roots from causing further damage and blockages. The completed project will better protect 20 properties from flooding in Thurstonfield.
Construction was undertaken in two phases. The first phase consisted of excavations to repair and replace the damaged sections of the culvert and took place throughout December 2020.
The second phase of the works consisted of lining approximately 200m of the culvert, completed in August 2021.
