Looks like the local government failed to built the monsoon drainage and possibly the existing drainage system are simply not enough. Also these drainage system could be filled with rubbish that were collected for long period of time.

Singapore used to have similar problems some 40-50 years ago. LKY and his team have managed to get this sorted which took more than 10 years.

People in Singapore always complain and grumble when PAP Government dig here and there to improve drainage systems leh!
