I hardly saw any slums in India. I do not know what that means. It might be that there aren't that many of them in Hyderabad, or that they are located in the parts of the city that I did not visit. Occasionally we would see a single "house" or even a row of them, here and there, mostly along the bigger roads close to the city center. There was also one such "house" on the empty land plot nearby Anil's parents' house. I was told that not all neighbors were happy about that poorer family living there and were surprised that Anil's parents would not ask them to leave.
On the last day of my stay in India it was raining heavily, and it seems that such weather is considered to be a perfect one to do laundry if you do not have running water at home:
