Mumbai Man Revives 100-Foot Borewell With Rainwater

Chetan Soorenji watched his Mumbai neighborhood dig deeper and deeper for water, chasing a resource that seemed to vanish with every new home built. What started as a 30-foot borewell serving three houses eventually plunged to 100 feet, bringing a new problem: the water tasted salty and unusable.

He remembered when the water tasted sweet at 30 feet. The solution, he realized, wasn't to dig deeper but to refill what had been drained.

Chetan researched groundwater recharge and discovered that rainwater harvesting could raise water levels naturally. His 50-year-old home couldn't handle major renovations, so he worked with what he had.

He connected his roof to the old 30-foot borewell with pipes, directing every drop of rain back into the ground. He also built a simple percolation pit where water could seep slowly into the earth.

Then he spotted another water source going to waste. His air conditioner produced 25 to 30 liters of water daily during Mumbai's scorching summers. After filtering it, he piped that water into the pit too.

Even vacant land near his home became part of the system. Two pipes now carry rainwater from that land underground instead of letting it flow into drains.

Chetan kept costs low by using pipes and fittings he already owned. Beyond building the percolation pit, the entire system required almost no money, making it easy for anyone to replicate.

The old 30-foot borewell, long abandoned, filled with water again. "After installing the water harvester, even the old well was recharged and now has water throughout the year," he says.

The Ripple Effect

The transformation spread beyond Chetan's property. Two neighbors discovered their borewells had refilled without them doing anything. Springs that hadn't flowed in years began running again.

"Today, we can see streams of crystal clear water flowing, like a small rivulet in our backyard," Chetan shares. The neighborhood's groundwater table had risen enough to reverse years of depletion.

His garden now thrives year-round with passion fruit, coconut, mango, mulberry, jamun, and vegetables. The plants never lack water, even during brutal summer months, because the ground stays saturated.

On his terrace, vines and plants create what he calls a mini forest. The green cover naturally shades the building and keeps summer heat at bay without air conditioning costs.

Chetan's advice is beautifully simple: "If you can't afford to spend much, then store the water flowing from your roof in a small tank." One person's decision to stop wasting rain brought an entire neighborhood's water supply back to life.
