Not One Lake Is Safe In Bengaluru — Not One

SIBY JEYYA

💧 Not One Lake Safe. Not One.


Out of 147 lakes left in Bengaluru, not a single one is safe to drink from. Not one is safe to bathe in.

Let that sink in.

In 1897, the city had around 2,300 water bodies. Today, fewer than 150 survive. And nearly all of them are polluted, encroached upon, or chemically unsafe.

This isn’t nature failing the city.

This is the city failing itself.



🏗 1. A 400-Year-Old Genius System — Destroyed


In the 1500s, Kempe Gowda built an interconnected chain of lakes. Overflow from one fed the next. Gravity did the work. It was sustainable, elegant, and resilient.

By the 1960s, about 920 lakes still existed.


Then came explosive growth.

The population jumped from roughly 4 million in 1991 to over 14 million today. Paved surdata-faces increased by over 1,000% in five decades. Lakes were filled to build bus stands, stadiums, and tech parks.

Dharmambudhi Lake? It’s now a bus terminal.



🚰 2. A City That Outsourced Its Water

Today, Bengaluru pumps drinking water 100 kilometers from the Cauvery River, lifting it 300 meters uphill — an expensive, energy-heavy workaround.


Why?

Because it wiped out the water system it once relied on.



🧪 3. Sewage Overload and Lakes That Catch Fire


The city generates around 2,120 million liters of sewage daily. It can treat only about 1,350 million.

The rest flows into drains and lakes.


Bellandur Lake alone receives nearly 40% of the untreated sewage. It has caught fire multiple times. Toxic foam spills onto roads during monsoons. Methane levels have been recorded at 1,000 times higher than in clean lakes.

This isn’t symbolism. It’s a chemical reality.



📉 4. The Numbers Are Brutal


Nearly 40% of lakes fall into the worst water-quality category for months at a time.
98% data-face encroachment.
90% receive untreated waste.


A $426 million World bank plan promises revival by 2029.

But the promises started a decade ago.


The real question isn’t whether Bengaluru can fix its lakes.

It’s whether it can fix the mindset that destroyed them.
