Constructed Wetlands for Holistic Kindergardens

Since 2023, four nature kindergardens built by LivingCircles GmbH have been equipped with their own treatment plants, even though they are located right in the city.
The educational concept of the institution is based on actively involving children in natural cycles and fostering a conscious use of resources. The aim is for children to experience how their own actions directly influence their environment. In line with this guiding principle, LivingCircles decided to integrate decentralized constructed wetlands into the local water cycle.

BW Green Building: A Milestone for Sustainable Construction near Stuttgart

, ,

The BW Green Building in Bietigheim-Bissingen redefines sustainable architecture with an innovative Constructed Wetland (CW) by J&S Engineers. The CW naturally treats greywater, and the purified water, combined with harvested rainwater from cisterns, is used to irrigate roof and facade greenery. This approach minimizes wastewater, utilizes excess nutrients for plant fertilization, and cools the building through evaporation, enhancing the urban microclimate. Designed as an attractive green terrace, the CW demonstrates how biological water treatment can be efficiently and visibly integrated into modern architecture.
