Abstract/Summary

The use of constructed wetland systems for purifying wastewater is an area of increasing importance in water resources management. Such systems typically include a combination of substrate, wetland plants, microorganisms, and fauna, such as earthworms. Efficiency of operation depends on composition and is variable over time due to reduced purifying capacity of constituents, changes in dissolved oxygen and susceptibility to clogging of the constucted wetland system. Therefore, the design and management of constructed wetland systems is very important in maintaining purifying capacity and system sustainability. This Special Issue of Water will bring together current knowledge of the design, operation and management of constructed wetland systems. The Special Issue will help inform the future development and implementation of effective constructed wetlands.
