If, in this analysis, there are no results that make construction unfeasible, that is, if the feasibility study is positive, then the planning phase of the public biological swimming pool can be started.
A biological swimming pool must be impermeable against the subsoil, in the majority of cases with a high quality plastic screen specially designed for swimming ponds.
The biological swimming pool allows bathing in naturalized, bath-quality, clear and transparent water. Water that is not harmful to human health or the environment, since these pools produce bathing water, through natural processes. No chemical additives, no salt, no chlorine are required.
The plants, in a biological swimming pool, play three important roles: oxygenation of water, assimilation of nutrients and shading of the water surface. Through plant bioactivity, clean, transparent and bathing water is, so to speak, poor in nutrients and rich in oxygen. It then provides an antiseptic function for organisms harmful to human health.
