Nallah-Hood: Toward a Healthy Mula Mutha
How can Pune’s waterways become an interconnected water system that not only holds, filters and distributes water but also provides social and cultural benefits? In order for Pune, India to harness the full potential of its watersheds it must see its river as one unified system of a river and its nallahs. Nallahs are seen as neighborhood waste canals but a design focus on Nallahs can unlock a multi-scalar approach to resilience in Pune. Nallahs are inherently decentralized, demarcate the low ground and have great potential to hold water. Pune’s watersheds or “Nallah-Hoods” could significantly help to mitigate issues related to flooding, water scarcity, pollution, and habitat loss. A water holding system cannot be realized without first taking an in-depth look at the pollution issues that surround the cities waterways. Our proposal is three-pronged. The first and most important system is the water holding network of Nallahs and interconnected infrastructures. The second and third system work in parallel. One system implements a web of physical waste collection and harvesting points that incentivizes communities to collaborate in the clean up their neighborhood. The other system filters and treats polluted nallah water before its eventual release into the Mula Mutha.
