Abstract:-Waste water treatment costs extra strain on every private and civic body. Previously waste used to be just dumped at refusal area without prior treatment. But it caused pollution and several environmental issues. Different treatment methods are implemented to treat this waste but are associated with certain limitations. Researchers have developed a wetland treatment method as a cost-effective technology dependent on nature for the treatment of waste. Vegetation and associated micro-organisms growing on wetland can break down the waste without charging extra operation cost. Constructed wetlands (CWL) are found to be capable enough to treat municipal, industrial sewage as well as stormwater runoffs. Pollutants present in wastewater are adsorbed by plants and microbes so their level is reduced down to make water reusable. In the present study, three case studies show evidence of the efficiency of CWL to treat different types of waste using locally available plant species. CWL also provides a natural habitat for living organisms and provides an aesthetic view for wetland landscape.
