23.1 Introduction

Constructed wetlands are one type of Sustainable Urban Drainage System (SUDS) that have been used for decades. They provide stormwater conveyance and improve stormwater quality. European regulations for water quality dictate lower concentrations for an array of dissolved pollutants. The increase in the ambitions of the removal efficiency for these systems on industrial areas requires a better understanding of the characteristics of stormwater and the functioning of constructed wetlands as SUDS.

For a detailed view on the achievements of constructed wetlands for stormwater on industrial sites, knowledge on stormwater quality and characteristics is essential as described in the next paragraphs:

  • Stormwater quality
  • Industrial stormwater quality
  • Fraction of pollutants attached to particles
  • Research on suspended solids
  • Particle size distribution.

The removal efficiency of constructed wetlands is considered in paragraph 23.2.4. Special attention is given to the Dutch situation as an example, since recent monitoring on the characteristics have led to an abundance of data on the ...
