Dharavi is one of the largest slums in Asia, home to over 1 million residents in just 2.1 square kilometers. It faces a major issue with access to safe drinking water, as many residents must purchase water from informal and unregulated sources that are susceptible to contamination. Both the national and state governments are responsible for ensuring access to safe water for all citizens according to policy, but implementation has been lacking, especially in Dharavi due to its large population and lack of formal land tenure, posing health risks that must be addressed.
