Work has started on a multi-million pound upgrade to a white water course at Stockton's Tees Barrage which will play host to Olympic athletes in 2012.
The £4.6m revamp will see four 35ft (12m) long Archimedes screws pump the water needed to create guaranteed conditions for white water competitors.
The screws are being made in Holland and will be moved to Teesside in July.
The site has already been confirmed as a pre-Games training camp ahead of the London Olympic and Paralympics Games.
Funding has come from Regional Development Agency One North East, Stockton Borough Council, Sport England and British Waterways.
Steve Garcia, project manager with British Waterways, said: "Once completed the new upgraded Tees Barrage white water course will provide the UK's first fully sustainable course."
Stockton Council leader Ken Lupton added: "The Tees Barrage is a real jewel in Tees Valley's crown and this investment is further testament to our commitment of creating world class sporting facilities."
The course is currently tidal driven, which means it can only be used three hours either side of low tide.
