This was specifically investigated for initiators of construction projects, like real estate professionals, property owners and developers.
The essentials are of particular interest for real-estate professionals, (public) property owners as well as developers who embark on a circular construction project, including renovations as well as building extensions.
For heating, ventilation, and air conditioning (HVAC) and other installations such as water, affordable reuse seems to be more challenging (also see essential 4).
From preliminary research, we found that initiators of construction projects, like real-estate professionals, (public) property owners and developers, play an important role in successfully realizing constructions that are circular and bio-based as wells affordable.

Introduction
China is a country with scarce water resources.
Water pollution control is gaining the attention of the people.
Fluctuation of water quantity is large because of water consumption is large in the day and is small in the night in the rural area.
Because of less demand for professionals, local labor can be fully utilized in constructed wetland management and maintenance.
