Secondary Treated Wastewater in Construction

Human life, as with all animal and plant life on the planet, is dependent upon water. Not only do we need water to grow our food, generate our power and run our industries, but we need it as a basic part of construction purpose. Now at present stage water is in great demand in the field of construction. So as to fulfill the demand in this project the water used in concrete is replaced by secondary treated wastewater from Sewage water treatment plant. Sewage treatment is the process of removing contaminants from waste water and household sewage, both runoffs (effluents), domestic, commercial and institutional. It includes physical, chemical, and biological processes to remove the contaminants. The aim of the present research work is to investigate the possibility of using the secondary treated wastewater for the purpose of construction works on continuous basis. By evaluating and comparing the compressive and tensile strength of the conventional concrete cubes and secondary treated wastewater concrete cubes it is found that the strength obtained is greater in secondary treated wastewater concrete cubes. Hence, on the continuous basis secondary treated wastewater can be used for the construction purpose.
