ABSTRACT
Constructed wetlands for stormwater comprise a sustainable development practice, as they can be implemented at various scales, can be distributed or centralized, and can produce multiple benefits. This chapter explores the planning, design, performance and sustainability features of stormwater wetlands and bio-retention basins. Comprehensive planning at the municipal or watershed scale is vital for the achievement of sustainable development. There are really two categories of problems associated with stormwater run-off. One is attenuating flow volume and run-off rate increases caused by development. The second is mitigating the pollution in non-point source run-off. The chapter discusses these challenges and demonstrates that management and treatment goals can be achieved simultaneously by constructed wetlands, while offering additional human and ecosystem benefits. It also discusses a case study of the Qunli National Wetland Park and the JEL Wade Park to emphasize the multifunctional advantages and sustainable development potential of stormwater treatment landscapes.
