Future pools could be 100% natural, without chemicals. More and more individuals are attracted to this possibility and now also municipalities are choosing them as an alternative.
In these pools you do not need to change the water every day. 19 different plants are responsible for filtering the water. It is then purified in two separate before returning to the main swimming pools.
Under the pool there are 10 kilometers of pipes which are checked several times a day.
But this system also has its drawbacks. Water quality should be tested four times a week to see if the plants have done their job properly. The pool users must shower before a swim and can not use sunscreens.
In central London, King’s Cross, there is a pool of this type of 400 square meters. Only 163 people can use it every day. The temperature of the water never exceeds 25 degrees Celsius.
