Constructed Wetlands and Waterways
Wetlands absorb large amount of water and contaminants from outside sources, and their micro-organisms (fungi and bacteria) efficiently decompose and recycle the nutrients. Water leaving a wetland is almost contaminant free and of good quality.
Wetlands were once considered useless wastelands and often used as waste disposal sites or seen as potential pasture. Today however, we recognise their importance as hugely diverse ecosystems. Restoration of wetlands and construction of new wetlands benefits not only wetland plant and animal species but also many other aspects of our environment and way of life.
Major benefits of constructed wetlands are: water quality, biodiversity, flood control, water levels and flows, community wellbeing, research and education.
