labor moved in, but there was no government effort to plan or invest in any infrastructure in or near Dharavi. The living quarters and small scale factories grew haphazardly, without provision for sanitation, drains, safe drinking water, roads or other basic services. But some ethnic, caste and religious communities that have settled in Dharavi at that time helped build the settlement of Dharavi, by forming organizations and political parties, building school and temples, constructing homes and factories.
