Ideals with the introduction to treated domestic wastewater utilized in concrete preparation where the scarcity of fresh water. Discuss the physical properties of materials and chemical properties of treated domestic wastewater experimental programme is presented in mix proportion of M20 grade concrete are present. Compressive strength results of M20 grade concrete cast by using treated wastewater. M20 grade at 7days the average compressive strength for all mixes will be same At the end of 14 days marginal increase in compressive strength. By using natural sand, M-sand and washed M- sand. Compressive strength at 28days will be higher, tensile strength of the concrete is nearly same and higher strength is achieved at the age of 28days. Flexural strength is comparatively high. At the age of 28days by using reclaimed water
