Zamrudhpur is a vertical slum township located near a posh residential area of Delhi. It consists of multi-storied structures where 6-10 people live crammed together in tiny single rooms with difficult conditions. Many residents are migrants who have lived there for 10-20 years or more, working as day laborers for neighbors. Sanitation is poor, with only one toilet for every 30 households and public toilets used mainly by men. The community has a heterogeneous population from various cultures and some local efforts are underway to improve sanitation issues.
