The existing conventional sewage treatment plant will be replaced by a two-stage constructed wetland. The chosen system will be executed as a raw wastewater treatment plant, which integrates sewage sludge and wastewater decomposition by a sequence of vertical flow constructed wetlands (12.500 m² filter area on 2,3 ha total area). The process principle of reed beds is described under this LINK. The new innovative and close-to-nature wastewater treatment plant will be established in 2020. It will be the largest constructed wetland in Southern Germany.
Design planning has been finished in May 2020.
