Excessive use of concrete, widespread construction and clogged drains led to the flooding of the streets after heavy rainfall and storm that was experienced on Thursday. The unprecedented rainfall in the city, apart from throwing life out of gear, highlighted the problems that have crept into the drainage system in Chandigarh.

Waterlogging, in fact, has become a perennial problem as after every rain, the drains are not able to handle the flow of water. the surface run-off is high and instead of facilitating recharge of ground water, the water is being wasted.
