With development of country and rapid increase in population, the demand for fresh water intakes has increased drastically. At the same time the production of kitchen and sewerage wastewater has increased proportionately. Therefore, the expenditure incurred due to fresh water supply and the disposal of wastewater has increased annually. Moreover, due to lack of proper wastewater treatment system, untreated wastewater has been discharged directly to the nearby environment polluting the environment and also posing the significant risk to the public health. Therefore these rapid urbanization has demanded for more sustainable and alternative methods of wastewater treatment system that can be implemented at a decentralized level besides the conventional and mechanized sewage treatment systems and septic tanks. This paper analysis the feasibility of Decentralized Wastewater Treatment System (DEWATS) to produce a highly efficient, viable, sustainable and eco-friendly, low cost solution for managing community wastewater in the hostel complex of the College of Science and Technology (CST) campus, Royal University of Bhutan.
