Abstract - Water from the kitchens, bathrooms, showers, tubs, and washing machines are referred as the grey water. Even though the grey water looks dirty, the treated grey water can be made useful in several beneficial purposes like irrigation and laundry purposes. The aim of this experimental study is to use the treated grey water in concrete making and to analyse its effects on the workability and strength aspects which can be utilized in concrete structures. The mortar and concrete compressive strength results obtained at 7 days moist curing time showed a significant increase. Mortar and concrete mixes using TGW cast at curing times of 28 days led to no significant effects on compressive strength.
