This study was carried out to analyze the treatment efficiency of water hyacinth constructed wetland system with greywater. Greywater was collected from Boys’ Hostel in SVNIT campus for constructed wetland reactor. Parameters such as pH, conductivity, BOD3, COD, TS, TSS, TDS and TKN were analyzed. This study was observed in two phases. Water hyacinth wetland system operated in continuous mode with 3 retention time 1, 2 and 3 day. In continuous system, water hyacinth wetland system operated for 5 days with each different retention time. From the results of the continuous system, it can be concluded that the water hyacinth wetland system will work efficiently for a retention time of 2 days with high removal of BOD3 and COD of 88.55% and 79.20%, respectively. TDS reduced by 56.76% in a continuous system, whereas, TS reduction occurred only by 14.03% in wetland operated with 2-day retention time. After the treatment conductivity, pH, TS, TSS, and TKN of greywater increased when operated in continuous modes as water hyacinth reintroduces nutrients to greywater. During the continuous operation of the water hyacinth wetland system, plant biomass also analysed  and observed for its growth. Water hyacinth increased by 61.83% by mass after the treatment. This shows the high greywater-suitability of water hyacinth for its growth.
