Archimedes screws used as screw pumps during day reversed as screw turbines by night . 8th Nov 2011 Following a multi-million pound makeover, the Tees Barrage International White Water Centre at Stockton-on-Tees is now re-open to the public. An extensive programme of improvement has created a world-class, Olympic-standard, facility, and the UK’s first fully sustainable pumped white water course. Senior GB team member and Olympic team hopeful, Laura Blakeman, one of the world’s top canoeists and ambassador for the new course, recently joined other professional kayakers to test-out the upgraded course in a competition event. After using the course, Laura said: “The Tees Barrage International White Water Centre is a brilliant asset for Stockton and the north east. Now we can boast a world-class training facility that will help us prepare for world-standard competition. We can also encourage international teams to base themselves at the Tees ahead of the London Olympic and Paralympic Games next summer. “Competing on the course was a great opportunity to try out the new features on the course. I think the course offers a real challenge to professional kayakers, as well as aspiring youngsters. It’s a much improved facility that can now be enjoyed by everyone.” Unlike other white water courses around the world, the Tees Barrage International White Water Centre is using four Archimedes Screws, an invention which was created over 1,200 years ago, to generate the flow of the water around the course. Unique design The quartet of screws, each one over 13 metres long, bigger than a double decker bus, and weighing over 30 tonnes individually, were specially designed and made in Holland by Spaans Babcock. The unique design of the hydro screw will be used to pump water around the course instead of the traditional method of using contained pumps. There will also be energy generated by water falling down the hydro screws running in reverse during low tide which in turn powers a generator creating electricity to sell to the grid and fund the pumping operation. This system means that the Tees Barrage International White Water Centre is the only sustainable pumped canoe course in the UK; and the only sustainable pumped canoe course in the world to exploit tidal fluctuations for power generation and course operation. Best in the world Steve Garcia, project manager, British Waterways said: “We are very pleased to see the upgraded course re-open to both world-class athletes and novice sports enthusiasts. The technical design and construction mean that the course is now one of the best in the world. It offers a sporting challenge and is now a sustainable facility for the public to enjoy. Everyone at British Waterways is looking forward to seeing kayakers and rafters out on the water, putting the course through its paces.” Other key improvements to the course include an upgraded deeper main channel, a new short course – one of the steepest in the UK, installation of a Rapidbloc system which allows paddlers to shape the waves and flows of the water and a new conveyor belt system. Chris Hawkesworth, planning and facilities manager, Canoe England said: “The improved course at Stockton-On-Tees now boasts some highly advanced features, including the Archimedes screw pumping system which is the first in the world that generates power for the electricity grid at night as screw turbine and is reversed to be used as screw pumps during day. This has been a great scheme to work on, and is the first time that renewable technology, innovative design and environmental improvements have all come together in the one project.” The Tees Barrage International White Water Centre has been designated a pre-Olympic 2012 training camp and can cater for both Olympic athletes and novice canoeists, or even casual visitors interested in white water rafting. This variety of usage is possible due to the flexibility of water flow allowed by the Archimedes screws system.
