Located in Brussels, Belgium, NEMO33 is officially the Deepest Pool in the World with a depth of 108 feet. The complex was designed by Belgian diving expert John Beernaerts as a multi-purpose diving instruction, recreational, and film production facility, and opened in 2004. 

The pool is filled with 660,430 gallons of non-chlorinated, highly filtered spring water.

 “The water that fills the pool comes from a spa and it’s heated by solar panels to keep it nice and warm.”

 Imagine jumping in to a pool minus the chlorine smell. The temperature is  maintained at 86°F and contains several simulated underwater caves at the 32 foot depth level. At this level there underwater windows that allow outside visitors to peer into the pools at various depths. The pool is a big hit with recreational scuba divers who are able to enjoy the constant controlled atmosphere and water temperature for varying levels of instruction. The pool has two large basin areas at depth levels of 16 ft and 32 ft, and a large circular shaft descending to a depth of 33m (108 ft). There are three permanent bells of air under pressure where air is renewed constantly, this aids instructors to spend more time with students at depth.
