Should storm water drainage networks be banned for all cities?

For most cities storm water drains collect rain water and dump it into the nearest river and thence to the sea. This is sheer waste. Rain water needs to be harvested and used to recharge acquifers. In most non desert countries even the most densely populated cities get enough rainwater to fully meet household needs of about 100 to 150 liters per person per day. But for some unknown reason governments prefer to dam distant rivers and build expensive canal and piping networks to transport that fresh water to the cities. It would be far simpler and inexpensive to pump up that water if only the ground water tables could be maintained by recharging...and that requires banning storm water drainage networks in the first place....any takers?


I am only referring to storm water drains...sewer networks can continue as they exist with some additional treatment facilities and recycling of grey water for gardening if possible...there is also some experiment by IIT Bombay which does this treatment in an environmentally optimal way.
