In a rapidly urbanizing India, it’s time to reimagine water in cities
Live MintThe cities of the Indus Valley civilization were renowned for their sewers, drainage channels and rainwater harvesting. Generations of civil engineers have been trained in stormwater design with one objective—to build pipes large enough to transport water from a “50-year storm” as quickly as possible. Recent failures of large infrastructure projects in India and globally have raised questions about the wisdom of bringing water from distant sources and routing stormwater and wastewater away. Another emerging trend is designing cities themselves to mimic natural systems—to allow more infiltration through “low impact development”, more green spaces and “room for the river”. We need textbooks and software packages that are updated and locally relevant to train a new generation of engineers and architects to reimagine water in cities.
