Nowadays, water supply and sanitation play an important role and impact more on public health and the environment. Day by day the urbanization increases due to population migration toward cities so the clean water demand increased, and hence, the water security becoming more important. In the context of India’s ongoing water crises, it is essential to explore alternative water sources and adopt effective management practices, particularly within the construction industry. In India, wastewater treated is discharged in water bodies. The wastewater from the tannery industry can be effectively utilized for construction purposes, helping to significantly alleviate water shortages. To preserve natural resources, the effective utilization of wastewater treatment is essential. Recently, WHO and UNICEF highlighted as climatic point it has grown demand for the wastewater treatment technology (WWTT) infrastructure especially in developing countries. Sanitary wastewater is typically processed using several conventional methods, including sewage treatment plant (STPs). Utilization of treated water in manufacturing of concrete and curing of concrete can be good approach toward sustainability. In this review work, the compressive strength and the tensile strength of M35 and M40 grade of concrete will be found by casting cubes with curing of concrete also carried out by using the treated wastewater. In this research, durability test through microstructural analysis such as SEM scanning electrons microscopy. In conclusion, treated wastewater presents a viable alternative water supply for concrete production, providing a sustainable approach to mitigate water scarcity and diminish the environmental impact of building.
