A natural facility created at a cost of just Rs 1.8 crore is treating 600,000 litres of sewage each day at Rajokri, a village on the border of Delhi and Gurugram.
This innovative project is a solution for cities struggling to deal with the problem of wastewater and not having the money to set up expensive sewage treatment plants (STPs).
A traditional, mechanised STP gets built for anything between Rs 7 to Rs 62 per thousand litres of sewage to be treated. In contrast, the natural system at Rajokri comes for just a little over Rs 1 per. . .
