Not only mumbai, but also in whole of India we lack planning a city. 1) Yamuna is contaminated 2) Ganges is polluted 3) Krishna is also getting dried 4) In chennai, one of a clean river in 19th century, coovam, is an open drainage.
Why all these happens? We didnt plan for a proper drainage. In all these cities, the drainage lines are redirected to the rivers flowing thru the city. Earlier, there were coupious ground water. So, what they thought is that for the purpose of driniking, people can take water from well and the drainage water can be linked to river so that it ultimately joins a sea/ocean. But the times have changed. Earlier in one ground (around 2400 sqft) only one house was there and maximum of 10 people lived. There were no motors to take water from ground, only well. So the water consumtion is less. But now, there will be atlease 4 families and 20 people living in same one ground. More water consumption, less ground water and u cant use the river water as it is fully contaminated. What can u do now? Take the example of US. Bring experts from other countries on how to plan for drainage & how to clean the river? How can US manage to have good drainage without contaminating their rivers? Take their advise. Nothing wrong in that.
