The use of wetland for stormwater pollution control

Developing and implementing a stonnwater management strategy requires several keycomponents. Research must be undertaken to develop local rainfall distribution statistics,determine stonnwater pollutant loading characteristics, determine the effectiveness of variousstonnwater treatment practices and identify design criteria for each type of the bestmanagement practice. The practice of urban stonnwater management has until recentlyfocused only on drainage and flood control. But now days more and more concern are takento reduce pollution's wash out loads to water recipients by implementing source controlmanagement, on-site treatment and building stonnwater pollution control facilities. In thearticle overview and basic principals of stonnwater quality management are presented.General stonnwater treatment and pollutant removal mechanisms are explained. Swnmaryresults of study of the pollution removal in constructed wetlands for stonnwater treatment aredescribed.
