The international water management institute system predicts that by 2025, one person in three will live in conditions of absolute water scarcity. When grey water properly managed, grey water can be a valuable resource for horticulture, agriculture growers as well as flushing for toilet. The paper presents a design of Grey water treatment system for treatment of grey water for residential area. The Treatment system combines biological treatment with physicochemical treatment .The Treatment system produced effluent of excellent quality, meeting the BIS quality regulation. Grey water treatment system was very efficient in removal of Suspended solids, Turbidity, Total hardness, Sulphate, Nitrate, Total phosphorous, Sodium, BOD, Total colliform, Faecalcolliform& E-coli. Total colliform, Faecalcolliform& E-coli is absent in produced effluent & that also met drinking water standards. Futher,the paper discusses the implications on the applicability of grey water reuse for toilet flushing purpose. Recyling of grey water reduces the amount of fresh water needed to supply and reduces the amount of waste water entering sewer or septic tank.
