In the most popular models, the swimming pool sector is structurally separated by the regeneration area (sector not too deep which contains permeable substrate) where the friendly micro-organisms (bacteria), reeds and watery plants filter water with their roots. These natural, biological and ecological swimming pools can be conceived to be adapted to any garden. They have, generally, a depth in the swimming area of 1.8 to 2 meters.

To maintain a natural aspect, the reserve structure of the swimming pool area, like concrete, stone or a walls recovering, will be darkened under the water surface. We think that the artificial structure of a biological swimming pool must be felt as less as possible, so you can really feel that you swim in a natural environment. However, our partners can also conceive swimming pools where structure is prevalent and where linear devices are used to gibe the desired effect.
