Thousands of conservancy workers employed by the Municipal Corporation of Greater Mumbai clean tonnes of garbage that is thrown into the city's streets and gutters every day. But it's this section of the society that is by and large ignored by the public. It took a lot of courage for photographer Sudharak Olwe to capture the lives of these people. All this has been presented in the form of a book titled In search of dignity & justice: The untold story of conservancy workers.
