Natural swimming pools

Ecological or natural swimming pools take advantage of the properties of certain plants and microorganisms to filter their water. It is a good alternative to conventional swimming pools.

How it works

Compared to a traditional swimming pool, a natural swimming pool consists of two zones, and an optional third, the water passing from one basin to another by a pump:

  • Swimming area: swimming pool, made up of few plants. 
  • Planting area: basin of the same size as the bathing area (maximum depth 50 cm), which includes purifying plants (water hyacinth, rush…) which role is to clean water and prevent pathogenic organisms from reproducing thanks to their oxygen production. 
  • Regeneration zone (optional): made up of oxygenating plants (elodeid, aquatic buttercup…) whose role will be to guarantee good water quality. This area is generally in the form of a waterfall. 

The choice of plants will depend first of all on the climate and the compatibility of the plants with each other.
