Based on directives of a central team which visited the city, the BMC is planning to seal large areas of slums by combining containment zones (CZs). On May 9, there were 2,643 CZs in the city of which one-third were in buildings while two-third were in congested areas.

From these 60 per cent, nearly half are manageable but the other half needs police support. Hence to ensure proper management, the BMC is planning to combine around 700 CZs.
