Dewatering the Hinkley Point C power station site calls for a massive pumping capacity. EDF’s new nuclear power station at Hinkley Point C, in Somerset, is one of Europe’s largest and most complex infrastructure projects. It is also one of the UK construction industry’s prize schemes, promising around £20bn-worth of work. When it’s completed, it will be the world’s most expensive nuclear power station. The first reactor is already on track for commissioning in 2025 and this year will see the project hit a number of major milestones, including the completion of the 4,500-tonne platform that will form a base for the reactor buildings. It’s still early days for main contractor Kier BAM JV, however. Construction of the network of tunnels needed to carry cabling and piping started in March 2017, along with work to construct a jetty and seawall. The accommodation blocks needed for the huge team of skilled trades required for a project of this size and scope, including 1,000 apprentices, have also been completed. One of the challenges of managing a site of this size and complexity, particularly given its low-lying coastal location, is the issue of managing rainfall and the tidal surges from the sea. To help manage this, Kier BAM has divided the vast site into six water managements zones (WMZ) and enlisted the help of pump hire specialist Sykes Pumps to provide the varied pumping solutions required for each WMZ over the course of the programme.
