Constructed Wetlands for Holistic Kindergardens

Constructed Wetlands, Innovations and Research, Sustainable Architecture

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.

DWA Climate Award: Janisch & Schulz Participates

Constructed Wetlands, Nature-based solutions, Sustainable Architecture

Janisch & Schulz is participating in the DWA Climate Award with a constructed wetland at the “Little Franklin” nature kindergarten in Mannheim. The system naturally treats wastewater on-site, avoiding discharge into the public sewer. The purified water infiltrates locally, creating wetland habitats that enhance biodiversity and serve as green, cooling areas. This project demonstrates how nature-based wastewater treatment can support climate adaptation in urban environments. The award winners will be announced at the DWA “Water Days” in Berlin in September.
