Series: Rainwater harvesting in chennai

Chennai is facing an unprecedented water crisis with the city’s main reservoirs running dry.

Part 1 and Part 2 of our series on rainwater harvesting (RWH) exposed how the government as well as citizens have failed in making the most of a scheme that, if implemented well, could have set Chennai as a worthy example in water management.

The state of our roads, which begin to resemble water bodies after even a brief spell of intense rain, is just one indicator of the poor state of water harvesting and storage in the city.
