Abstract
The purpose of this permaculture-based research is to create a sewage purification system using plants that can purify all sewages produced during a building construction. Different analyses and evaluations of water quality on a rain circulation system of a solid biotope type in KYOUDOU-no-MORI were carried out. The results show that further improvement of this system can not only enhance its purifying capacity of sewage materials, but also make it more environmentally friendly in future. Therefore, the authors have decided to carry out experiments and develop the existing permaculture system to an edible landscape based rich ecological system.
