Very good initiative! It’s missing only one component to make it fully sustainable - using Bioenzymes based cleaning products so that toxic chemicals from the HUL cleaning supplies does not contaminate.
There are 16 such Suvidha centers in Mumbai already and from what I know they plan to expand to 25 by next year. Would love to see such models come up in other cities with other players as well.
This is awesome news, Thank you for sharing, I guess Dharavi shouldn't be called a slum anymore, if they are doing these things that are not done in most of the elite residential complexes
this is such an eye (and mind) opener ! One would never have believed this would be in any realm of possibility, especially in a slum (such are our biases) - wonder why it hasn't garnered the publicity it deserves? Great example of if there's a will..... Thank you for sharing.
The Sewage Treatment process being used at Dharavi probably does NOT use the Nutrients, N and P, but merely filters them out.
A more scientific solution would be to use the nutrients to produce the oxygen required to treat the sewage. During photosynthesis nutrients, N & P, are consumed to produce O2.
The question is what to grow using sewage?
Diatom Algae are the best type of phytoplankton / micro-algae,
they can be grown in underground tanks using electric lights, so space is not a problem.
Thank you for writing and sharibg this new perspective on climate solutions, very informative, are there any specific grades for treated water and its usage in turn for flushing, landscaping or washing. I suppose the grades will be higher in that order.

Thanks for writing about your experience! I hope this is replicated elsewhere.

Thanks, Anindita! Hope to see more examples like this :)
A broader connection between sewage and climate change is that people buy food and fuel.
Food contains nutrients, N & P, and fuel releases CO2.
The nutrients can be used to grow Diatoms to consume the CO2.
Diatoms are consumed by fish.
So the final result would be that the Carbon goes into fish and O2 remains in the water or escapes into the atmosphere..
