St Germans Pumping Station – new UK record? DAVID THOMAS, MIDDLE LEVEL COMMISSIONERS


For only the second time since the new St Germans Pumping Station was commissioned in 2010, all six pumps were run to test the systems and clear silt deposited by the tide at the rear of the station. St Germans is the largest fl ood risk and


water level management pumping station in the UK and is the single point of exit for water falling on a 700km2


catchment, containing


24,500 houses. Its target capacity against an average tide is to lift 100 tonnes of water per second (cumec) from the Middle Level Main Drain into the tidal River Great Ouse, 4 miles from Kings Lynn in Norfolk. Whilst this fully automated and high tech


station has consistently shone in achieving its goal in keeping the low lying fens free from arterial fl ood, it is always good to know what you have in hand. Hence, two years ago the station was tested for the fi rst time with all six pumps running and at that time it achieved 102 cumecs. On this occasion the pumps were able to pump a combined 112 cumecs – more than

Fo llowing the December meeting Southery & District IDB's Chris Thorpe was presented with a watch to mark his 25 years’ service with the Board. Chris commenced employment with the Board in 1988


as a general drains man. He was promoted to mower operator, then to excavator driver and more recently was made up to Assistant to the Operations Manager. Chris said that he had been very happy


working for the Board and hoped to continue to do so for many years. Continuing, he commented that the success of the Board is down to the teamwork which is enjoyed by all the staff .

to good design and also to the decision to maintain the concept of a straight pumping path, which, during construction, meant that the station had to be built within the existing discharge channel. This in itself presented


any such station has pumped before in the UK. As was the case last time, the station


achieved this feat with no complications and whilst water levels close to the station intake dropped markedly as additional pumps were called to duty, the intake path was smooth and linear. This was a testament


several signifi cant challenges, requiring the prior installation of a coff erdam large enough to house a football pitch. The test not only proved the ability of


the station but also provided valuable data, which will be used to assist with planning the management of major events. Engineers will appreciate that modelling data is useful but real world data is of greater value. In this instance, three pumps were run from the mains supply drawing in the region of 3 megawatt s and the remaining three from three of the six 2,200 horsepower diesel generators. In just under an hour around 300 megalitres (one megalitre is equivilent to one million litres) of water were pumped which, whilst appearing a lot, was only a third of the total pumped in the previous day during this wet period and a just a small fraction of that which was pumped over a fi ve days period during Christmas 2012, when 21,600 megalitres were evacuated from the Middle Level system via St Germans.
