Natural swimming pools

Natural swimming ponds

Public and private swimming ponds can be designed as natural outdoor pools with a highly aesthetic biotope appearance and without using chemicals like chlorine.

For the natural purification of the nutrient load (nitrogen and phosphorus) and a hygienically safe state, the pool water is re-circulated between the swimming area and a regeneration zone, which consists of planted soil filters for an environmentally friendly water treatment.

In 2006 we realized the redevelopment of the conventional bath pool in the city of Goettingen, Germany, in a natural pool. The treatment is implemented by constructed wetlands and shows the natural character of the system.

The water treatment plant is dimensioned for an average number of approx. 1,200 swimmers per day. It works without any chlorine or chlorine dioxide. We apply a special filter material to realize continuous high flow rates on the one hand and an effective treatment concerning disinfection and turbidity on the other hand. The regeneration and following recirculation of the treated water bases only on biological and physical processes.
