Press release
Leigh flood storage area expansion schemeSecretary of State agrees Environment Agency plans to increase reservoir capacity. ![]() Increasing the amount of water that can be held in the Leigh flood storage area will mean more properties in Tonbridge and Hildenborough can be better protected from flooding The Environment Agency’s proposal to increase the maximum level of water that can be stored in the Leigh flood storage area has been approved by the Secretary of State for Environment, Food and Rural Affairs. The Environment Agency can now start work to enable the Leigh flood storage area to store more water, increasing its capacity by nearly a quarter. Enlarging the reservoir also means that a new flood embankment can be constructed in Hildenborough. Once complete, over 1,400 homes and businesses in Tonbridge and Hildenborough will be better protected from flooding. Sally Harvey, Environment Agency Area Director, Kent, South London and East Sussex, said:
Cllr Robin Betts, Tonbridge and Malling Borough Council Cabinet member for environment and climate change, said:
Tony Hills, Kent County Council Deputy Cabinet member for the Environment, said:
Christian Brodie, South East Local Enterprise Partnership Chair, said:
The scheme is being delivered by the Environment Agency in partnership with:
Funding is through the government’s Flood Defence Grant in Aid (FDGiA), with contributions from Tonbridge and Malling Borough Council, Kent County Council and the South East Local Enterprise Partnership. Next stepsThe Environment Agency expects to appoint contractors in spring 2022. Work is expected to start on site in summer 2022 and the scheme completed in autumn 2024. Further informationThe investment is part of plans outlining £5.2 billion of investment over the next 6 years. More than £860 million will be spent in 2021/22 boosting design and construction of more than 1,000 schemes across England as part of the Environment Agency’s annual capital programme. The delivery of the new schemes follows the successful delivery of the previous programme. The government invested £2.6 billion in new flood defences through this programme – surpassing its target of better protecting 300,000 homes between 2015 and 2021. The new schemes will be an important part of the implementation of the government’s Flood and Coastal Erosion Risk Management Policy Statement and the Environment Agency’s Flood and Coastal Risk Management Strategy. Homes and businesses better protected from floodingThe Leigh flood storage area currently better protects 1,200 properties from flooding. Once the expansion is complete, over 1,400 homes and businesses in Tonbridge and Hildenborough will be better protected from flooding. BackgroundIn 1982, the Southern Water Authority completed the Leigh flood storage area (FSA). The FSA reduces the risk of flooding to around 1,200 homes and businesses in Tonbridge and Hildenborough. It works by storing the peak of a flood upstream and releasing it in a controlled manner once the peak has passed. The flood storage area sits between the villages of Leigh and Penshurst in Kent. When full, it covers approximately 278 hectares. It is formed of a 1.3 kilometre long, 5 metre high earth embankment across the Medway valley. The River Medway itself passes through 3 steel gates built into the embankment. These gates control the amount of water flowing downstream by either letting the river flow normally, or restricting the flow to hold water in the storage area. The FSA is an ‘online’ storage reservoir, which means that the river is always flowing through it. Currently the Environment Agency can legally store water to a maximum level of 28.05 metres above ordnance datum (AOD), as measured at the control structure. Investigations showed that storing water to 28.6 metres AOD will reduce flood risk to more properties. Proposal to increase the level of stored waterIncreasing the maximum stored water level required permission from the Secretary of State for Environment, Food and Rural Affairs which has now been received. Since 2019, the Environment Agency has been working with organisations and landowners who are affected by the proposal. The Environment Agency submitted its application to increase the maximum stored water level to the Secretary of State in early June 2020. A number of objections to the application were submitted to Defra which were unable to be resolved, therefore an inquiry took place between April and May 2021 to allow concerns to be heard. The Environment Agency responded to the concerns raised by all respondents at the inquiry and the inspector submitted a report with recommendations to the Secretary of State in July 2021.
