Rainwater Harvesting For Farms: Turning Every drop into diamond

As we find the evidences of depleting groundwater level, in form of urban water crisis, the urgency of having a solid roadmap for water conservation becomes necessary.

According to World Bank, 163 Million Indians lack access to safe drinking water, the country being the world's largest extractor of groundwater, and 89% of this extraction being used for agriculture.

Why Should Every Farmer Care About Rainwater Harvesting?

1. 60% of Indian farms still depend only on rain

2. Groundwater level is falling 1–3 metres every year in many states.

3. One good drought can wipe out your entire year’s income

4. Tube-wells are getting deeper, electricity bills higher, and water saltier

   
   

But here’s the good news:

The rain that falls free on your field can fill your wells, your ponds, and your children’s future, if you just catch it properly.

Real Benefits You Will See in 2–3 Years

1. Crop yield increases 30–100% (real numbers from hundreds of villages)

2. No need to wait in queue for tankers in summer

3. Borewell that was 300 ft dry starts giving water again at 100 ft

4. Soil becomes softer - less diesel for ploughing

5. Vegetable & fruit farming becomes possible even in summer

6. Fodder grows → more milk → more income

7. Women do not have to uphold the dual burden of walking 2–3 km for water

Simple Rainwater Harvesting Methods That Actually Work for Small Farmers

1. Farm Pond (Khuddi Talai / Dobha)

• Dig a pond in the lowest part of your farm (even 50 ft × 50 ft × 10 ft is enough)

• Line with ordinary plastic or cement only if you can afford (even without lining it stores water for 6–8 months)

• Cost: ₹40,000–₹80,000 (government gives 50–90% subsidy in most states)

• Stores 10–15 lakh litres – enough for 2–2 acres of protective irrigation

  
  

2. Contour Bunds + Trenches (Shet Tale)

• Make small bunds along the slope of your land

• Dig continuous trenches (CCT) or staggered trenches on the upper side

• Rainwater slows down, sinks in, and charges your borewell

• Cost: almost zero if done with MGNREGA labour

• Most successful method in Vidarbha & Marathwada

3. Recharge Pit for Borewell/Tubewell

• Dig a 10 ft × 10 ft × 10 ft pit, 20–30 ft away from your borewell

• Fill with pebbles, sand, boulders (3 layers)

• Divert rooftop + field runoff into this pit

• Your borewell water level can rise 20–50 feet in just one monsoon

4. Check Dams / Cement Plugs

• Perfect if a nala (stream) passes through or near your village

• Even a 3–4 ft high loose stone or cement plug can store lakhs of litres

• Entire village benefits – groundwater rises for everyone

5. Rooftop Harvesting (Even for Cattle Shed or Small House)

• Connect your tin/rooftop pipes to a dug pit or directly to borewell recharge

• 600 mm rain on 1000 sq ft roof = 60,000 litres free water every year

  
  

Government Schemes You Can Use TODAY (2025–26)

1. Jal Shakti Abhiyan - Catch the Rain → up to 90% subsidy

2. MGNREGA → free labour for digging ponds/trenches

3. PM Krishi Sinchayee Yojana (Per Drop More Crop) → ₹50,000–₹1,50,000 per farmer

4. Maharashtra’s Magel Tyala Shettale → farm pond completely free for SC/ST & small farmers

5. Rajasthan’s Mukhyamantri Jal Swavlamban Abhiyan → still active

Your first step could be :

1. Start with contour trenches – cost is almost zero. One season’s extra yield will pay for a pond.

2. Your Next Step (Start This Week!)

3. Walk your farm after the next rain. See where water flows out.

4. Mark the lowest point for a pond or trench line.

5. Talk to 4–5 neighbours.

6. Visit your Gram Panchayat and ask for Jal Shakti/MGNREGA work.

7. Start small. Even one trench this year will show results next year.

Remember:

The rain god doesn’t discriminate. He sends the same rain to everyone. The difference is who catches it.

Farmer brothers and sisters, let us make our villages water collecting chambers.

Let our children never know what water shortage feels like.
