Constructed Wetlands

A constructed wetland is an engineered ecosystem designed to optimize specific wetland characteristics and functions to improve water quality. Constructed wetlands provide long-term, effective treatment of tile drainage.

Smart Wetlands

Smart Wetlands, an initiative of The Wetlands Initiative, specifically sites, designs, and constructs tile-treatment wetlands to improve water quality in Illinois. Their website includes several resources for better understanding the impact of constructed wetlands on nutrient reduction.
