Waterfalls enchant, because the water bouncing over the stones causes pure euphoria. Hearing the murmur of water sounds like a promise. We already idealized the freshness of water, a shady place nearby, rest on hot days when we dream of relaxing in an environment to replenish our strength.

In biological swimming pools, waterfalls are also used. It may be that we need a vertical treatment due to lack of space to implement a water table of a certain size. Sometimes there are walls to take advantage of in the context of biological pool project. Transformation into a cascade wall, lined with ferns and mosses, creates a vivacious appearance and contributes to the biological treatment system. A small waterfall can also be a transitional element between an external biofilter and the basin of plants where the water visibly passes and not through tubing.

Waterfall walls that we frame in biological pools thus play a functional and ornamental role. Consequently, the choice of this water treatment element depends on the quality of the water to be treated, the configuration of the biological treatment system and the aesthetic concept for the site.

Waterfalls enchant, the lively green plants that cover the waterfall grow luxuriantly and the soundscape attracts life, visitors to the place, whether with paws or feet.
