Malaysia is experiencing water pollution crisis recently. In particular, greywater discharge directly to drains. Therefore, a greywater treatment system was designed to overcome this drain pollution. To investigate the operation and performance of the treatment system, constructed wetland was designed and builds for a small single household. Lepironia Articulata was chosen for populating wetland. The wetland was supplied with kitchen greywater. The selected house is appropriate because it lacks proper drainage system. This study evaluates the characteristic of kitchen greywater before and after treatment. The quality parameters of greywater that involve in this study are Total Coliform and E-coli. The range for reduction efficiency for Total Suspended Solid was 16.02 to 60.56, E.coli was 26% to 51% and Total Coliform was 5% to 63%. Generally, this study showed improved kitchen greywater quality before discharging to the nearest water body. The findings can be used significantly to enhance the knowledge in constructed wetland where it can serve as effective and integrated solutions for managing greywater discharging using control at source approach. A constructed wetland was best chosen due to its good visual impact, removal efficiency of organic material and other pollutant, as well economical.
