Abstract — The majority of disease spreads through the sources of water and the waste produced should to be treated before it is finally disposed-off in the open or in the natural water body for its further purification by self-purification process. In the area where there is unavailability of the treatment plant for the treatment in wastewater treatment plant as the cost of construction is very high and in such cases the water is directly thrown in the open land and this wastewater reaches the underground water table and contaminating the whole aquifer of the water present in that area and as there is unavailability of water treatment plant so people in such areas use the underground water directly causing various water borne disease. In such areas where the cost is one of the major factor, there the constructed wetland can be use very effectively as the cost of construction and maintenance is very low and can serve as an effective mean of treatment of domestic waste water
