World is set to get deepest indoor diving pool with depth of 45 meter
Soon the world will get its deepest indoor dive pool which will be as deep as a 15-storey building. Created for divers to train themselves, it is 45m deep and will hold 8,000 cubic meters of water. Located in Poland, the pool's water will be filtered 15 times a day while the normal pool is filtered only 3 times a day. It will be open by this spring with warmer water temperatures. Efforts are done to keep it transparent.
