Statement: Of the 478 storm water drains identified for clean-up before monsoon in the city, only 167 have been taken up, and work on these is still under way.
Assumption I: There is a shortage of manpower owing to which the authorities are not able to take up the task of cleaning of all the storm water drains.
Assumption II: The authority has taken up clean-up of only those storm water drains which are in areas susceptible to water logging.
Because of inadequate data none of the assumptions is implicit.
