Underground Water Detection App

Updated July 2026 · ~5 min read

You do not need an expensive detector device to get a strong first read on underground water. Satellite data plus AI does the desktop-study work instantly, from your phone.

Detect without a device

The app reads NDVI/NDWI satellite indices, terrain elevation and regional geology to estimate underground water probability, depth and quality at any point.

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.

When you still want a device

Physical detectors (resistivity/ERT, ADMT, PQWT) are valuable to confirm a shortlisted point on site. Use the app to pick where to survey, then survey there — saving time and money.

Works anywhere

Pick any location on Earth; the app and voice guidance support 33 languages.
