Chennai floods are not a natural disaster-they've been created by unrestrained construction
An earlier report from India Water Portal Rain rain go away, our cities can't keep the water at bay!: "Instead of introspecting and understanding the reasons for their sources drying up, the cities looked outside. Bangalore turned to the Cauvery, Hyderabad to the Krishna and Delhi to the Ganga and now all the way up to the Giri near Renuka in Himachal Pradesh. "City administration feels that water demand cannot be fulfilled locally. So the city with more political clout goes farther away to get its water. Meanwhile, property rates keep rising and politicians and builders make money by trying to sell off floodplains as prime residential destination," says Anupam Mishra. "But when it comes to monsoon, you can't dictate God that we already have water for our need so please give us only this much rainfall," he says.

These floodplains and lakes in the low-lying parts of a city, did not just fulfil the water needs of a city, but also drained it off the excess rain water that poured there. When construction blocked the path of water, it led to water-logging on the city roads. The blame then fell on the storm water drains which in most cases, were designed very long ago and were not capable of handling the excess water that seeped into the ground. The 'Mumbai Marooned' report says that the city's drainage system was designed in the early 20th century for a maximum rainfall of 25 mm per hour, assuming that half the rain would be absorbed by the soil and only half would flow into the drainage system."
