Deepest Swimming pool in the World : Nemo 33 is an indoor non-chlorinated fresh water facility in Brussels, Belgium.

Nemo 33 is an indoor non-chlorinated fresh water facility in Brussels, Belgium. It held the record as the deepest outdoor pool in the world between its opening on 1 May 2004, and the completion of Y-40 in Montegrotto Terme, Padua, Italy on 5 June 2014.The pool's maximum depth is 34.5 metres (113 ft). It contains 2,500,000 litres (550,000 imp gal; 660,000 US gal) of non-chlorinated, highly filtered spring water, maintained at 30 °C (86 °F) by a solar heater, and holds several simulated underwater caves at the 10 metres (33 ft) depth level. Due to the warm temperature in the pool, divers can dive for extended periods without a dry suit. The complex was designed by Belgian diving expert John Beernaerts as a multipurpose diving instruction, recreational, and film production facility in 2004. Popular Mechanics rates Nemo 33 as one of the top 18 strangest pools in the world. It is the deepest pool in the world poland.The depth of nemo 33 was recorded the deepest.

Polish adventurers and would-be divers will soon be able to take the plunge in the world’s deepest swimming pool.

Based southwest of Warsaw in the town of Mszczonów, the Deepspot pool will reach 45 metres deep. The pool will hold 8,000 cubic metres of water — or the equivalent of 27 25-metre swimming pools.

When the venue opens its doors in autumn 2019, it will take the world record from the Hotel Montegrotto Terme, whose own pool, the Y-40 Deep Joy, reaches a mere 42 metres.

The team behind the project hope that the pool will be the perfect place for professional or experienced divers to practice their skills, although beginners are also welcome. If you don’t fancy getting wet, meanwhile, a special viewing tunnel will also reach out under the water itself.

Deepspot won’t hold its crown for long, however. The Blue Abyss swimming pool in the English city of Colchester is already poised to snatch the world record with a 50-metre-deep pool, set to open in 2020.
