Consultancy Assignment: Domestic Wastewater Family Home
In Belgium the most popular system to treat the wastewater of single family homes, is a vertical subsurface flow constructed wetland. This system requires less surface area compared to other constructed wetlands. A disadvantage is the necessity of a pump to distribute the wastewater on top of the wetland.
