Underpasses are terrible for coastal cities that receive a lot of rain. I am thinking in particular of places like Mumbai in the monsoons, where the water accumulates much faster than you can pump it out (enough to keep it dry-ish at all times). There is also the problem of where to pump it to, esp. if the tide's up and all the drainage is already full.
- user_7832 4y agoAs a Mumbaikar living in the Netherlands (where OP appears to be), you're right - such underpasses will be a terrible idea in the monsoon season for Mumbai-like places. However for the Netherlands, rain is much more evenly distributed across the year and even "heavy" rain days are much lesser than the amount of rain a tropical city like Mumbai gets - which is why it's unlikely to be a major issue in the NL. (Side note I don't think there are pumps at every underpass if at all, perhaps only if the underground drains/sewers overflow. Also NL maintains high sea walls/dykes partly out of necessity so there likely will be place to pump it here.)
