Local bodies are responsible for the removal, collection and disposal of solid waste in urban areas. Until recently, the conservancy section of the city corporations and pourashavas carried out waste management, including sanitation, cleaning and other associated functions, while the transportation of waste and other engineering functions were performed by another department. As that system weakened the chain of command, Dhaka City Corporation recently inaugurated a waste management department to perform all of the waste management functions in a combined manner under a single line of authority, but this approach has yet to be replicated in other urban areas across the country.
