The constructed wetland is a shallow, earthen impoundment or group of cellular impoundments, which contain hydrophytic vegetation, designed to treat both point and nonpoint sources of water pollution. Its primary physical components include the aquatic vegetation, substrate for plant and microbial growth, the basin or cells, associated structural devices for water management, and the water that flows through the system.

In wetland ecosystems, there are biological, chemical, and physical processes that naturally clean and filter water. The waste treatment mechanisms it employs are a complex mix of physical, chemical, and biological processes. Manmade constructed wetlands are designed to mimic the processes found in a natural wetland ecosystem. They use wetland plants, soils, and microorganisms to clean water in a way that is often less expensive than more traditional water treatment systems. When properly designed, built, and operated, a constructed wetland can provide high-quality water treatment, while also adding aesthetical enhancement and wildlife habitat to your site.

This course focuses on the use of constructed wetlands used to treat wastewater, with much of the course addressing the implementation of constructed wetlands for the use of treating agricultural and livestock effluent.
