What is rainwater harvesting?

Rainwater harvesting is the process of collecting and storing rainwater — from rooftops, paved areas, or open land — for later use or to recharge groundwater. The stored water can be used directly for irrigation, cleaning, and other non-potable purposes, or allowed to percolate underground to replenish depleted aquifers. Tools like filters, storage tanks, and recharge pits make this process efficient for homes and businesses.

Why is rainwater harvesting necessary in India?

India faces mounting pressure on its water resources, making rainwater harvesting more of a necessity than a choice. Here is why it matters.

  • Low rainfall capture: India captures only about 8% of its annual rainfall due to inadequate harvesting infrastructure, losing the rest to runoff.
  • Heavy groundwater dependence: India is the world's largest user of groundwater, drawing on it for the majority of both irrigation and drinking water needs.
  • Falling water availability: Per capita water availability in India has declined to around 1,100 cubic metres, close to the internationally recognised water stress threshold.
  • Government mandates: States such as Tamil Nadu, along with cities like Pune, Mumbai, and Bengaluru, have made rainwater harvesting compulsory in new buildings to slow groundwater depletion.

→ Key takeaway: With India capturing only 8% of its rainfall and relying heavily on shrinking groundwater, installing your own rainwater harvesting system is one of the few water-security steps a household can take directly, rather than waiting on infrastructure or policy.

What are my financing options to buy rainwater harvesting tools?

When buying rainwater harvesting tools, you have two straightforward ways to pay. Here is how they compare.

  • Pay the full amount upfront: Pay the entire price, ranging from Rs. 4,500 to Rs. 19,500 depending on the tool, at the time of purchase.
  • Use the Bajaj Finance Insta EMI Card: Get a pre-qualified card loan of up to Rs. 6 lakh and split the cost across 3 to 60 months, without needing a separate credit card.

→ Buyer scenario: A homeowner buying the Rainy FL - 300 filter at Rs. 19,500 can use the Insta EMI Card to avoid paying the full amount upfront, spreading it across a tenure that suits their monthly budget instead of dipping into savings for a one-time purchase.

The table below shows how the same Rs. 19,500 purchase breaks down across different tenures, so you can see how a shorter or longer repayment period changes your monthly EMI.

 

TenureIndicative EMI
3 monthsRs. 6,500
6 monthsRs. 3,250
12 monthsRs. 1,625
24 monthsRs. 830

Disclaimer: These are indicative figures based on a simple division of the product price across the tenure shown, with no interest, processing fee, or other charges factored in. Your actual EMI amount will depend on the terms of your card loan offer.
