Constructed Wetlands for Pollution Control

Target Audience

Open to all (researchers, practitioners, policymakers)


This module evaluates the use of constructed wetlands (CW) in the treatment of municipal and industrial wastewaters, partially-treated effluents, run-off water and sludges. Following a review of the relevant legislative and regulatory framework associated with the discharge of treated effluents it considers the typical design criteria used for horizontal flow, vertical flow and other forms of constructed wetlands, together with their construction and commissioning, whether as new build or retro-fit.

Learning Objectives

In addition, a series of case studies are used to explore the operation, performance, treatment efficiency and ultimate renewal/replacement procedure of a variety of CWs operating under different conditions, with different types of influent, in different locations. The module evaluates the applicability, benefits and limitations of CWs as a treatment technology together with the impact on carbon footprint when using this sustainable wastewater and sludge treatment technology.
