Keadby Pumping Station is the outfall for the River Torne within the Isle of Axholme to the Tidal River Trent. It comprises six gravity sluices which maintains water levels within the Isle of Axholme and discharges fluvial flow to the Trent when tide levels permit. High flows are pumped via six pumps, providing approximately 32m3/s discharge capacity when required.
Continuing to manage flood risk in the Isle of Axholme is vitally important. Ending water management activities could result in extensive flooding to many thousands of homes and businesses, over 30,000ha of high-grade agricultural land, internationally important conservations sites and major critical infrastructure. A total of 15,761 residential properties, 921 businesses and 3 major road networks were at risk and the economic assessment has valued the area at £5.2billion over 100 years.
The detailed project appraisal for short term and long term continued operation of the pumping station (gravity and pumped discharge) included hydraulic modelling and a full economic assessment for each of the proposed options.
