In a future world, the population is going to be under high water scarcity according to WorldWater Development (UN) report. Countries of Africa and Asia like Cambodia, Bangladesh, China, and India are still developing are likely to face water scarcity more. It was expected that by 2055, 70 to 75 % of the population will leave in the city of India. With the shrinking of water, low rainfall, etc it is difficult to provide water to such a high population. Water is one of the most highly consumed materials in the world. Scarcity of fresh drinking standard water is becoming evident due to increasing population, improvement of lifestyle, climate change, and lack of appropriate water resource management. Therefore, the conservation of freshwater is becoming an important issue. The study reported 825 billion liters of freshwater were required to satisfy the world's concrete requirement in 2010. This research aimed to use treated industrial wastewater as a substitute for fresh water in the mixing and curing of concrete. Water samples were obtained from the central wastewater treatment plant of Chittagong Export Processing Zone (CEPZ), Chittagong, Bangladesh which generally is disposed to the Bay of Bengal after treatment. Firstly, treated wastewater quality is examined and compared with the relevant standard of pure drinking water. Cement setting time and mortar flow were evaluated using both freshwater and treated wastewater. Both types of water were used to produce and cure concrete. Workability, compressive strength, and Ultrasonic Pulse Velocity(UPV) tests were conducted on the concrete samples. It is concluded that treated wastewater could be a replacement for freshwater in the production and curing of concrete and can help to save a large amount of valuable freshwater and thereby achieving sustainability in the concrete industry. This study tries to provide problems arising due to waters car cities in India.
