Feature: Poland digs world's deepest swimming pool

Swimmers in Poland are set to dive into the world's deepest pool in late 2019.

Known as "DeepSpot", the pool has caused a buzz due to its spine-chilling depth, which reaches 45 meters -- roughly corresponding to the height of a 15-story building.

"Engineers appreciate the enormity of the challenges associated with the construction of such a pool. It's a piece of extreme engineering," DeepSpot Marketing Manager Bartek Wiecek told Xinhua.

To fill it, owners will pour in over 8,000 cubic meters of water. When complete, "DeepSpot" will be open to public but will be of special interest to divers and marine professionals. The complex will also boast a hotel, restaurant and conference center.

"DeepSpot will be the best solution for divers who want to improve their skills. It will deliver safe, comfortable, stable and perfect environment for diving training. It will be completely independent of external weather and open 24/7/365," Wiecek adds.

The water temperature will be slightly higher than in traditional facilities of this type, meaning divers will not need special thermal insulation foam.

According to the owners, the vast structure will boast the water equivalent of 27 Olympic-sized swimming pools and use advanced technology to filter the water flow and maintain pristine clarity.

The pool is located on the outskirts of Warsaw, at the town of Mszczonow.

"Locals are excited about our investment and support us very much. They invested a lot of time and money in the development of geothermal energy in their area, which caused that we decided to build DeepSpot there," Wiecek adds.

What makes this pool special is that it will be 16 feet (4.9 meters) deeper than the present record holder in Montegrotto Terme, a town in the north of Italy.

Wiecek says divers from all over the world are sending in questions, as well as people interested in the construction problems which must be solved to make the project possible.

"It is noteworthy to mention that a force of 50 tons acted for 1 square meter of the retaining wall. One wall of the excavation was 30x30 meters, which means that the construction of the excavation had to withstand the pressure of 180,000 tons of soil," Wiecek told Xinhua.

The developer is also responsible for the well-known FlySpot indoor skydiving tunnels which imitate parachute jumps in an aerodynamic tunnel.

Another "DeepSpot" attraction will be a state-of-the-art underwater tunnel for spectators, where they can watch people diving without getting wet.
