Free Groundwater Survey Online

Updated July 2026 · ~6 min read

A paid survey has its place — but you should never pay just to find out whether a plot is worth surveying. That first pass can be free, for any location on Earth.

What "free survey" should include

• A groundwater probability score for the exact point you choose.
• An estimated depth band to target.
• A water-quality indication.
• A recommended drill point with a survey direction.
• A shareable PDF report for your driller.

JalDrishti is free worldwide: unlimited groundwater scans, reports, maps and a bore calculator, with voice guidance in 33 languages. You only ever pay if you choose an optional certified-geologist review.

What a paid survey adds

A resistivity or seismic survey physically probes the subsurface at the points you nominate. It is more definitive than any remote analysis and worth paying for before a deep or expensive bore. The saving comes from arriving with a shortlist rather than asking a crew to test the whole property.

Typical drilling costs this avoids

Drilling is priced per metre, and a dry bore still costs the full amount. Depending on country, terrain and depth, a failed borewell commonly runs from several hundred to several thousand US dollars — which is the entire reason to spend time on siting first.

How to run yours in a minute

• Install the app on Android or iOS.
• Drop a pin on your plot or search the place name.
• Run the scan and read the score, depth band and drill point.
• Download the PDF and take it to your driller.

Is there a catch?

No advertising wall on the report and no credit card for the core app. The business model is the optional certified-geologist review and the provider marketplace, not the scan itself.
