CONSTRUCTED WETLANDS FOR SEWAGE TREATMENT
A constructed wetland is essentially, a shallow basin filled with a substrate, usually sand and gravel, and planted with vegetation tolerant of saturated conditions. Constructed wetlands are efficient sanitation technologies and act as bio-filters that remove a range of pollutants from wastewater. They also increase the biodiversity in urban areas and present exciting opportunities for decentralised wastewater treatment in the city.
