Flooding has a devastating effect on people, property, business and agriculture and can have an impact in terms of insurance. While LMDB does not have a statutory duty to prevent flooding, our systems by their very nature protect people, property and infrastructure on a daily basis. In addition the Board has undertaken many specific protection schemes in villages such as North Cotes, Great Carlton and Willoughby in partnership with the District Council, Lead Local Flood Authority (County Council), and the Environment Agency all of which have subsequently increased the level of protection offered to residents, their properties and businesses.
LMDB aims to provide a level of protection against a 1 in 75 year rainfall event for urban areas and a 1 in 10 year rainfall event for agricultural land. That said, we cannot afford to stand still and we undertake periodic studies of our catchments to keep abreast of the effect that climate change, rising sea levels and development or change of land use might have on our systems. Should a review show a need for increased capacity within a system, then provision is made for the necessary work to be undertaken within the works programme.
The LMDB depot is located in the centre of its area (out of the flood plain) and a Duty Officer and Works Supervisor or Foreman are on call 24/7 to offer an urgent response to major problems. Two 12” and two 6” ‘fish friendly’ pumps are on standby for use at pumping stations should there be a pump failure or to help with localised flooding during extreme weather. All Pumping Stations are also fitted with a connection for an emergency generator should the mains power fail. Work to further improve the flood resilience at Pumping Stations throughout the district has also commenced and is due to be completed shortly.
During a heavy rainfall event, the control room at Manby is manned 24 hours a day, with a shift system in operation for control and operational staff.
Staff in the control room monitor the telemetry system which provides immediate access to information and allows remote control of all pumping stations across the LMDB district. This enables us to identify any issues and to deploy staff quickly to the relevant area. Pre-emptive measures may also be taken in advance of any forecast heavy rainfall such as lowering water levels so there is more capacity to store the water in our systems.
