Subhajit Mukherjee, the founder of city-based NGO, Mission Green Mumbai, has found a cost-effective solution to the problem of rainwater wastage using PVC pipes and a water barrel/drum.


In an exclusive interview with The Better India (TBI), Mukherjee revealed that the idea was initially shared by retired IPS officer and governor of Pondicherry, Kiran Bedi, almost a month ago.

“I spoke to her and researched further about how a system like this could be adopted. I got in touch with engineers at IIT Bombay who were able to help with the modifications required to make the system effective. Even they thought that the idea was cost-effective and wouldn’t require complex engineering knowledge to build. And, at the same time, it would give us immediate results.”

How does the system work?
