Overview
In the canal belts of Rajasthan water arrives on a roster, not when the crop needs it — a farmer might get a few hours once a fortnight. A diggi is the answer: a lined tank that captures that allotted water (or rain) and holds it, so a drip or sprinkler system can draw on it steadily instead of the field going thirsty between turns.
The subsidy is large because the structure is the whole point. Small and marginal farmers get 85% up to ₹4 lakh; other farmers get 75% up to ₹3 lakh. The tank has to be lined to stop seepage in Rajasthan’s soils, and it pairs naturally with a drip or sprinkler set — which is why farmers often apply for both together on the Raj Kisan portal.
What you get
The benefit as the state notifies it — nothing here is an estimate.
- 85% subsidy up to ₹4 lakh for a small or marginal farmer to build a diggi.
- 75% up to ₹3 lakh for other farmers.
- Stores rostered canal water or rain so a drip/sprinkler system can irrigate steadily between supply turns.
- Pairs with micro-irrigation, which carries its own subsidy — the two are often claimed together.
Who is eligible
State schemes usually state their criteria as prose rather than a checklist. This is that prose, unpacked — the department’s verification is what decides.
You qualify if
- Farmer cultivating in Rajasthan, in a canal or water-scarce area
- Land record in your name of sufficient size for the tank
- Applying before construction starts on the Raj Kisan portal
- Bank account for the subsidy transfer
Not covered
- Diggis built before sanction — the subsidy is not paid retrospectively
- Unlined structures that do not meet the specification
Documents you need
Have these ready before you start — most rejections are a missing paper, not a missing right.
- Aadhaar card
- Jamabandi land record
- Bank passbook
- Raj Kisan portal application
How to apply
Fewer steps than a central scheme, and usually one office rather than a portal.
- 1
Apply on Raj Kisan before building
Register and apply at rajkisan.rajasthan.gov.in. Applying before construction is what makes the diggi eligible.
- 2
Build to the lined specification
Construct the diggi after sanction, lined to the required specification so it holds water in Rajasthan’s soils.
- 3
Verification and subsidy
The department verifies the completed tank against the sanctioned specification and releases the 75–85% subsidy.

A lined on-farm tank that stores rostered canal water or rainwater, so a drip or sprinkler system can irrigate steadily instead of the field going dry between supply turns.
