How to Recharge Borewells Through Rainwater – A Complete Guide
“Borewell Dry? Blame the Sky — or Not Harvesting It Right.”
Introduction:
Across Maharashtra, hundreds of borewells run dry by April. But here’s the good news: you can recharge your borewell using the rainwater from your own rooftop!
Why Borewells Go Dry?
- Over-extraction
- Poor rainfall absorption due to concrete surroundings
- No groundwater recharge system
Solution: Borewell Recharge Using Rooftop Rainwater
Instead of wasting rainwater into drains, channel it into a recharge pit directly connected to your borewell’s aquifer.
Basic System Includes:
- Catchment (Roof)
- Gutter System
- Filtration Chamber
- Recharge Pit / Borewell Casing
How It Works:
- Rainwater collected from the roof flows through gutters
- Passes through mesh & sand filter
- Clean water flows into the recharge pit
- Pit allows water to percolate and refill the borewell below
Key Points for Maharashtra:
- Works well in both urban homes & farmhouses
- Needs permissions in some cities – check with the local civic body
- Can recharge borewell with 40,000 – 2 lakh litres per year, depending on roof size
Maintenance Tips:
- Clean roof & filters before monsoon
- Desilt the recharge pit every 2 years
- Use non-corrosive gutters to ensure no blockage
Common Issues to Avoid:
- Using PVC gutters that crack or deform
- Overflow due to improper pipe slope
- Lack of an inspection chamber
