Constructed Wetlands for Reclaimed Water Treatment
- Course Number: C1071
- Credits: 1 hours
- Instructor: Ellen C. Huang, PE
- Price: $10
Course Outline
This course introduces constructed treatment wetlands through the Orlando Wetlands, a large-scale advanced water reclamation system that has operated since 1987. Students follow reclaimed water from the Iron Bridge Regional Water Reclamation Facility through inflow structures, deep marsh, mixed marsh, hardwood swamp, and outfall controls. The course explains the physical, chemical, and biological mechanisms that remove nitrogen and phosphorus, the importance of hydraulic control and water-quality monitoring, and the long-term need for sediment and vegetation management. The Orlando case study also demonstrates how treatment infrastructure can provide wildlife habitat, public education, recreation, and broader watershed benefits while maintaining its primary water-quality function.
At the end of this course, there will be a multiple-choice, open-book quiz, which is designed to enhance your understanding of the course material.
Learning Objectives
At the conclusion of this course, the student will:
- Explain how constructed wetlands use vegetation, soils, microorganisms, and controlled hydraulics to polish reclaimed water.
- Describe the treatment sequence and major hydraulic and ecological components of the Orlando Wetlands.
- Differentiate the principal mechanisms responsible for nitrogen and phosphorus removal in free-water-surface wetland systems.
- Identify key monitoring, operation, maintenance, and renovation practices needed to sustain long-term treatment performance.
