How Surat Man Turned Rainwater Into a Sustainable &  Profitable Bottled  Water Business

13 May 2025

Making rainwater drinkable and bottling it for sale is an untapped opportunity. Surat's Rahul Kacha shared how this free resource can be turned into a profitable and sustainable business.

Before starting, Rahul researched the science behind collecting and purifying rainwater. He learnt about filtration methods, storage solutions, and regulations for selling bottled water.

He then built two massive storage tanks: one with a 2 lakh litre capacity and another with a 1 lakh litre capacity to harvest rainwater.

These tanks were equipped with an effective pumping and filtration system, ensuring a steady supply of water for purification and bottling.

To install all of this, Rahul pitched his idea to investors and secured Rs 35 lakh to build his facility. Crowdfunding and government grants are also potential funding options.

He then procured approvals from FSSAI and local water boards -- required to sell bottled water in India. Ensure your facility meets safety and hygiene standards before launching.

Rahul also educated potential customers about the potential of rainwater harvesting and bottling. This helped create demand and trust, while helping others adopt RWH.

Today, Rahul supplies filtered rainwater to over 150 households in Surat. Begin by targeting eco-conscious consumers and expand by partnering with retailers and institutions.

Beyond his business, Rahul assists others in setting up their own rainwater harvesting systems. Expanding services can increase impact and profitability.
