The Mumbai waterlogging problem is here to stay. I believe the main reason to be the following: 1.Indiscriminate landfill operations to make land for constructing towers. 2.No outlets of adequate capacity to let the flood waters into the sea during hightides. 3.Blocked gutters failing to remove waste water. 4.An outdated network of drains and spillage built by the British now woefully inadequate. It is not only the Mithi river but many low lying water channels that have been severely encroached during the dry season. The life of the people in these encroached water channels beds is hellish in the monsoons. Yet people breed and live there to eke out a living in the city to everyone's peril. One of the solutions is also to rehabilitate those who have encroached into these channel beds elsewhere and like the Mithi, widen them allowing the storm waters to flow into the sea. Landfill operations around these channels must be stopped. So also the building activity around. Like the roads we need to develop these waterways to the sea, else there is no end to the monsoon horrors year after year.
