---------------------------------------------------------------------------------------------------------------------------------Abstract- Scarcity of water has become a major issue. With the increasing population water demand also increases. This report initiates natural method for grey water treatment called phytoremediation. The technique of phytoremediation is an engineered natural way to treat waste water using properties of wetland plants. For the remediation of grey water a small-scale unit is constructed and laboratory reports of various parameters are compared. Reports have promising results, including reduction in BOD and COD levels, complete removal of oil and grease, reduction in turbidity etc. Keywords- Grey water treatment, phytoremediation technique.
