Through this study, it was identified that the system is capable of removing organic and inorganic impurities such as Total Suspended Solids (TSS), Total Dissolved Solids (TDS), Nitrates, COD, BOD and microbes. The results acquired from the analysis of treated grey water can be used for agriculture, planting, gardening, car wash or any other domestic purpose.

I. INTRODUCTION The discharge of domestic sewage pollutes most of the water resources. Due to indiscriminate discharge of wastewater, most of our water bodies, surface as well as groundwater, are suffering from pollution. The contaminant load often exceeds the natural capability of that water body to dilute it to a harmless form. Sewage encourages the growth of phytoplankton, and due to extensive growth of which, the oxygen level of the water bodies gets depleted, causing an adverse effect on the faunal life. Organic and inorganic impurities, are present in the sewage, also there is very high concentration of bacterial growth, pathogens, viruses, causing waterborne diseases. So Instead, this domestic sewage/ greywater can be treated with the help of a constructed wetland with a view of reducing the pollutant load and also reusing it for activities such as gardening , car washing and other similar activities after the water is brought within safety parameters after treatment.
II. LITERATURE REVIEW AUTHOR AND YEAR :- Ram Bahadur Singh Maharajan (2012) TITLE: - The Potential Role Of Water Hyacinth In Wastewater Treatment DESCRIPTION This study examines the efficiency of water hyacinth plants in wastewater treatment. Reduction in concentration of BOD, TN, TP were observed and analysed for four weeks. Through this experiment it was observed that, there was clear reduction of the nutrients/pollutants in the treatment system having water hyacinth plant. AUTHOR AND YEAR :- Atif Mustafa (2013) TITLE: - Constructed Wetland For Wastewater Treatment And Reuse DESCRIPTION: In this study, A pilot-scale constructed wetland was tested for removal efficiency of various physical and chemical parameters from pre-treated domestic wastewater. AUTHOR AND YEAR :- P.M Diaz (2016) TITLE: - Constructed Wetlands and Water Hyacinth Macrophyte as a Tool for Wastewater Treatment DESCRIPTION: Through this Study, the efficiency of a bio-hedge based water hyacinth system is highlighted. The sand filtration method is also outlined. The different removable factors and the mechanisms used for their removal are also mentioned
