Is the water quality of a Piscina Biológica® always good?

The water is transparent and complies with all the standards required by law for bathing water quality.

The water quality of the Piscina Biológica® depends greatly on the water quality of the first filling. We can not use all waters, e.g. those contaminated by microorganisms whose levels already exceed standards for bathing water. Also the chemical composition has to be below certain values, especially those of the nutrients for plants. Any necessary pre-treatment has to be defined at the stage of project design.

Therefore, a water analysis is mandatory before beginning the planning of the Piscina Biológica®.
