The demands also included regular drinking water supply, underground sewerage connections and integrated stormwater drains.

They also sought pattas for eligible long-term residents of government and temple lands, while protecting water bodies and catchment areas. Sale deeds were sought for those who had paid for houses built by the Tamil Nadu Urban Habitat Development Board.
