| Every summer, big Indian cities — Delhi, Chennai, Bengaluru, Hyderabad — run dry. In Delhi, the Jal Board now sends out more than 1,000 water tankers just to keep people going when the piped supply fails. This is no longer a rare emergency; it has become a normal yearly crisis. As NITI Aayog’s Composite Water Management Index (CWMI) warns, our cities are using far more water than they actually have. The deeper truth is that this is less a shortage of water and more a failure of how we manage it. |
1 · The crisis in one idea — water lost before it arrives
| Non-Revenue Water (NRW): The water a city treats and pumps but never earns money from — because it leaks out of old pipes, is stolen, or is never billed. In simple words, it is water that is produced but lost on the way. In India, this has historically been around 50% — meaning nearly half the water never reaches a paying tap. |
- The strange paradox: The same city can flood after a few hours of rain, yet stand in tanker queues a few weeks later. Both happen because the city can neither hold rainwater nor stop its leaks.
- Living beyond means: Cities keep drawing more groundwater than nature can refill, so the underground water level keeps dropping year after year.
- Why it matters: Water security is not just about quantity — broken, on-and-off supply also lets dirty water seep in, making safety a problem too.
2 · The crisis in four numbers
|
~50%
of water historically lost as Non-Revenue Water
|
~30%
leaks away from pipes before reaching the user
|
1,000+
tankers Delhi deploys daily for basic survival
|
<20%
NRW target set by AMRUT 2.0 for cities
|
| How to read this: the first two numbers reveal the quiet leak — half the water lost, a third bleeding from pipes. The third shows the desperate coping — a tanker army. The last is the goal — cutting losses below 20%. Notice the smartest fix is hidden in plain sight: simply stop the leaking, and a “new” water source appears for free. |
3 · Why our cities keep running dry
A. We have buried our natural sponges
- Lost lakes and ponds: Cities have built over their lakes, ponds, and stormwater channels — the natural buffers that once soaked up rain and slowly refilled the groundwater.
- The result: With nowhere for rain to go, water now floods the streets in the monsoon and vanishes by summer, instead of being stored underground.
B. We chase faraway water instead of fixing what we have
- The distant-sourcing trap: Rather than repairing leaky old networks, cities keep hunting for far-off rivers or drilling ever-deeper borewells — an expensive habit that ignores the real problem.
- Borewell overdraft: This pulls up groundwater faster than rain can ever replace it, slowly emptying the underground store.
C. Our pipes are old and leaking
- Decaying infrastructure: In many city systems, nearly 30% of water simply leaks out of cracked pipes before it ever reaches a home — pure waste.
- The double danger: Leaky sewer lines also let raw sewage escape and mix into nearby groundwater, turning a water-quantity problem into a health hazard.
4 · Way forward
| Hunt the leaks before building dams. Run a time-bound “leak hunt” — physically audit and fix high-leak pipe stretches. Saving even a few percent of lost water equals an entire new local source, at a fraction of the cost. |
| Audit big users and plan openly. Quickly check the biggest bulk consumers — government buildings, malls, large campuses — for waste, and publish an honest emergency plan showing storage levels and ward priorities. Transparency calms panic and curbs hoarding. |
| Reuse every drop of used water. Cheaply upgrade existing sewage treatment plants and mandate dual-piping in new high-rises — so treated greywater (used water) handles flushing and gardening, sparing precious fresh water. |
| Build “Sponge Cities”. Add permeable pavements and revive lakes and floodplains so rain soaks into the ground instead of flooding the road — letting the city store water naturally, the way it once did. |
| Find the money to repair. Since city bodies are cash-strapped, a small ring-fenced water cess on property tax — locked only for cutting pipe losses — can fund the unglamorous but vital repair work, alongside AMRUT 2.0 support. |
| India’s urban water crisis will not be cured by one giant dam or pipeline. It needs a quieter, smarter shift — from reacting with tankers each summer to fixing the system all year round. Stop the leaks, store the rain, reuse the used water, and share honest plans with citizens. The cheapest new reservoir a city can build is the water it is already losing. Saving that is the surest path to a water-secure urban India. |

| India’s recurring urban water crisis is a failure of governance rather than of nature. Examine the structural causes and suggest how a shift from supply-side projects to demand-side management can secure urban water. (15 marks · 250 words) |
Structure hint:
Introduction — Note the normalised summer crisis (Delhi’s 1,000+ tankers) and the ~50% NRW problem.
Body Part 1 — Structural causes — encroached water bodies, the distant-sourcing trap, decaying leaky pipes.
Body Part 2 — The flood-then-drought paradox and groundwater overdraft.
Body Part 3 — Demand-side fixes — leak hunt, bulk-user audits, wastewater reuse, transparency.
Way Forward — Sponge City model, dual-piping greywater, AMRUT 2.0 targets, ring-fenced water cess.

Conclusion hint: Argue that the cheapest new water source is the water a city already loses — making leak reduction and reuse the heart of sustainable urban water governance.
