Abstract: In India, about 38,255 million liters of sewage produced daily, out of which only 22% of the sewage is being treated. Wetland construction is a solution for the treatment of sewage water through the natural process of growing a plant. In this experimental setup, a wetland is constructed to investigate the performance of Typha latifolia when planted in sewage water and investigated for a period of 4 weeks. The constructed wetland (CW) setup was filled with sewage water with a hydraulic retention period of 7 days. Within the stipulated period of 4 weeks, the change in the characteristics of the sewage was tested for every 7 days. During the treatment period, the plant Typha latifolia has considerably reduced the chloride content by 29.69% and the BOD content by 20.51% in the sewage. Hence, it is inferred from the project that the plant species Typha latifolia has the ability to reduce the saline nature of the water. It is also noted that the efficiency of the treatment of sewage water by the plant species increases with the increase in the time period in which the CW system is maintained properly.
