An official of the West Bengal Pollution Control Board gave Outlook a lowdown on the fetid state of affairs. “There are difficulties in implementing projects due to the fact that much of the area has now been claimed by promoters, developers and slumlords. Demolition has never been on the agenda of governments since these are votebanks. Rehabilitation attempts, too, have failed because the livelihood of most of the inhabitants of these slums, lower economic groups forming the ‘urban poor’, who work as sweepers, cobblers, rickshaw pullers, domestic workers, etc, lie nearby.” Unemployed youth who live along the banks of the sewer (that is, the Adi Ganga), says the official, are often involved in criminal activities and used by political parties as musclemen during elections, always on a quid pro quo basis. “They usually enjoy unspoken immunity against any kind of eviction activity, which is a prerequisite of the clean-up drive.”
