The worlds largest water tank dedicated to diving will be built at the popular Twinwoods Adventure centre.
Building the 30 metre deep dive chamber will take around two years, costing £3.6million.
It will be tunnelled underground to a depth of 20 metres with the remaining 10 metres above ground and will require 4.4 million litres of thermal water - making it the world’s largest volume tank dedicated to diving.
The centre, based in Milton Ernest, near Bedford, and formally known as Bodyflight, has recently been renamed Twinwoods Adventure due to its growing collection of action sports facilities.
There is indoor skydiving, surfing, climbing, shooting, racing and simulated base jumping, along with a health club including a pool and spa along with hotel accommodation.
The new pool, expected to create 20 new jobs, will not just be used for recreational diving. It will also be available for organisations requiring water based training or research and development facilities, such as the emergency services and the military.
A Twinwoods Adventure spokesman said: “The whole dive community, including both scuba and free divers, will benefit from this awesome venture enabling all levels of training courses, competitions, product testing and leisure diving to take place in a warm and safe environment.”
It will include the installation of enormous acrylic glass windows to the pool’s depths, which will provide a mesmerising backdrop to the centre’s restaurant.
The pool will use innovative heat exchange technology to temper the water, which will utilise free energy generated by the Bodyflight wind tunnel.
The adventure centre, based at Twinwoods Business Park, now employs around 50 staff and recently celebrated its 10th anniversary.
