Every farmland deal that goes wrong in south India goes wrong the same way. The buyer checks the title, checks the survey number, walks the boundary, signs -- and finds out in the second summer that the borewell the seller demonstrated in December runs dry by March.
Title problems are recoverable. You can litigate, you can compound, you can wait. A dry plot is not recoverable. You either drill deeper, buy water by tanker, or hold an asset that produces nothing.
So verify water first, before you spend a rupee on legal due diligence.
The three sources, and what each actually guarantees
Borewell. A private bore on the plot. Guarantees nothing by itself -- depth, yield and recharge matter far more than the existence of a pipe.
Canal. Fed from a reservoir through a government-run network. The strongest guarantee available, but only if the plot sits inside the official command area and only for the seasons the canal is scheduled to run.
Tank or kere. Traditional tank irrigation, filled by monsoon runoff. Reliable in a good year, useless in a bad one, and increasingly compromised by upstream encroachment.
A plot can have all three and still be water-poor. A plot with one good canal connection can be worth double its neighbour.
Verifying a borewell
Ask for three things. If the seller cannot produce them, treat the bore as unproven.
1. The drilling receipt. It states the depth drilled and the depth at which water was struck. A bore drilled to 800 feet that struck water at 750 is a very different asset from one that struck at 200. The first is scraping the bottom of a falling aquifer.
2. A yield test you attend. Not a demonstration -- a test. Run the pump continuously for at least two hours and watch the discharge at the outlet. A bore that starts strong and thins after forty minutes has low recharge. Measure it crudely: time how long the discharge takes to fill a known container, and do it at the start and at the end of the two hours. If the second measurement is materially lower, the bore is being drained faster than it refills.
3. The month you are testing in. This is the one buyers skip. A bore tested in December, after the northeast monsoon, tells you almost nothing about April. If you are buying between November and February, assume the yield you see is the annual peak and discount it heavily. The honest test window in most of peninsular India is late March to May.
Walk the neighbouring plots too. Ask the adjacent farmer what depth their bore is at and whether they have deepened it recently. A cluster of farmers who all re-drilled in the last three years is telling you the water table is dropping, whatever the seller says about this particular plot.
Verifying a canal connection
Canal water is allocated by command area, and command area is a mapped, official thing -- not a matter of proximity. A plot fifty metres from a canal that sits outside the command area gets nothing.
Ask for the plot's survey number and check it against the command area records held by the irrigation department division office for that canal. In Karnataka this sits with the Water Resources Department; in Maharashtra with the irrigation circle offices; in Tamil Nadu with the PWD Water Resources Organisation. The record you want confirms the survey number is ayacut -- inside the irrigated area -- and states the sanctioned extent in acres.
Then ask a question most buyers never ask: where on the canal is this plot? Head-reach plots, near the source, get water first and get it reliably. Tail-end plots get whatever is left after every farmer upstream has taken their share, which in a dry year is nothing. Two plots in the same command area, same paperwork, can have completely different real-world reliability based on position alone. Ask the neighbours which reach they consider themselves in. They will know immediately.
Verifying tank irrigation
Tanks are the hardest to assess because their condition changes year to year.
Look at the tank itself, not the paperwork. Check the bund for breaches and the sluice gates for whether they still operate. Check the catchment upstream for new construction -- a tank whose feeder channels have been built over will not fill regardless of rainfall. And check whether the tank is on the revenue records as a live irrigation source or has been quietly reclassified.
Tank-fed plots are worth buying when the tank has a functioning water user association that actually desilts it. Ask who maintains it. If nobody can name anyone, the tank is decorative.
The seller tricks worth knowing
The borrowed bore. The pump being demonstrated draws from a neighbouring plot's bore, connected temporarily. Trace the pipe physically, all the way, before you accept a demonstration.
The wet-season visit. Viewings scheduled only between October and January. If a seller resists a summer visit, that resistance is the information.
The green crop. A standing crop proves water was available for that crop's cycle, not that water is available year round. Ask what was grown in the previous three cycles. A plot that only ever grows a single short monsoon crop is a rain-fed plot being sold as an irrigated one.
The "borewell point". A dowser's mark and a promise that water is available at 300 feet. This is a cost you are being asked to absorb, priced as if it were an asset. Value the plot as though it has no water, because it has none.
What to do with the answer
Water quality matters alongside quantity, and it is cheap to check. A basic water test at a district agriculture lab covers salinity, pH and total dissolved solids for a few hundred rupees. High TDS rules out several horticultural crops entirely, which changes what the land can earn and therefore what it is worth.
Once you have verified water, the rest of the due diligence sequence follows: the ownership record, the encumbrance history, the chain of title. Start with how to read an RTC or Pahani, then work through the Encumbrance Certificate and the mother deed and chain of title.
If you are buying in Karnataka specifically, the full sequence is laid out in the step-by-step Karnataka farmland buying guide. For a wider view of what farmland actually returns once water is accounted for, see the farmland investment guide.
