Sustainable Waste Water Treatment in Developing Countries: A Case Study of IIT Kharagpur Campus
Abstract Treatment of wastewater and its reuse in irrigation and agriculture can mitigate the inevitable scarcity of safe drinking water in coming decades. For developing countries like India and especially in its under-privileged regions, it is high time to focus on sustainable wastewater treatment which will be economical and easy to construct, operate and maintain by unskilled users without much dependency on electricity. Addressing this issue, various sustainable methods of wastewater treatment was critically analyzed and the Waste Stabilization Pond system was selected. A facility was designed for 20,000 residents of Indian Institute of Technology Kharagpur campus based on its geo-climatic and wastewater characteristics. Detailed calculations were carried out to demonstrate the effluent quality with reduced BOD and E-coli is suitable for unrestricted irrigation. This project with minor customisation can act as a prototype for adjacent vast rural areas where land is available but water, electricity and skilled technicians are not. If implemented, this project will bear social benefits beyond campus such as water supply to drought prone areas, better harvest and rural employment. Moreover, it underpins government’ several initiatives to develop rural infrastructure and inclusive growth of the country.
