At the edge of a small temple lane in Bengaluru’s Sampangiram Nagar, a circular stone well sits behind a metal grill canopy.

A few years ago, most people walked past it without stopping. Some avoided going near it at all.

Plastic waste floated on the surface. Broken concrete and silt had settled at the bottom. Tree branches hung low over the opening, dropping leaves and debris into the water. The stone walls had cracked in places, with weeds pushing through gaps that had widened over years of neglect.

For many residents, the well had stopped feeling like a water source long ago. It had become a dumping ground.

Today, the same well draws people to it every day.

Residents arrive with steel pots and plastic buckets. Water is pumped into an overhead tank connected to public taps. Families collect water for daily use through the day. Small eateries nearby use it for cleaning. On days when municipal supply is irregular, the well becomes a source they can turn to.

Even in difficult summers, it continued to hold water.

For a city where many families now plan their days around tanker timings, dry borewells, and uncertain water supply, this change matters. A forgotten well becoming useful again may seem like a small neighbourhood story. But in Bengaluru, it points to a much larger possibility: old water systems can still help a growing city face its present water crisis.

The Sampangiram Nagar well is one example of a wider effort across Bengaluru. Residents’ welfare associations, citizen groups, and environmental organisations are restoring traditional wells that had slowly disappeared from public memory as borewells and piped supply systems took over.

When Bengaluru’s water disappeared underground

For decades, Bengaluru’s water story slowly moved underground.

As the city grew, borewells began replacing open wells in homes, schools, apartment complexes, and public spaces. What was once visible to everyone, a well in a courtyard, beside a temple, or inside a neighbourhood, gradually disappeared behind pipes, pumps, and motors.

Deep drilling gave neighbourhoods access to groundwater far below the surface. It felt convenient. Turn on the motor, and water would come up.

But this also changed how people understood water.

With an open well, the water level is visible. After good rain, people can see it rise. During dry months, they can see it fall. The well reminds a neighbourhood that groundwater depends on rain, soil, and recharge.

A borewell does the opposite. It hides the water level deep underground.........
