Dr CSP OJha, professor of civil engineering, IIT Roorkee believes that Cleanliness of Ganga could be achieved spending half the budget allotted for ‘Clean Ganga’ campaign using eco-technology. The professor has been associated with cleanliness operations undertaken on various rivers for the past 25 years.
According to Dr. Ojha, “Central government had spent Rs. 939 crore till Feb 2014 on the Ganga Action Plan under different schemes. But, there are many cost-effective waste water treatment options which can expedite the rejuvenation of the river Ganga,”
By using technologies like soil scape filter, soil aquifer treatment and green bridge, we can treat waste water. If waste water passes through green bridge in the sewerages, it would be filtered before falling into the river and organic pollutants, bacteria and viruses could be removed,” he said.
Dr Ojha views explaining the major problem in cleaning the river is disposal of sewerage. He said “”Two-third waste and sewerage water is still being disposed of in the Ganga. There is a need to treat this water first to bring Ganga nearest to its pristine form
