Where to dig a well?

A fast, worldwide first estimate of the depth to groundwater and how promising a location is for drilling a water well — plus an optional, detailed AI report in your language.

How it works

  1. Pick a location — click the map, enter coordinates, or use your current location.
  2. Get the depth for free — estimated depth to groundwater, unlimited. This is free.
  3. Unlock a location — spend 1 credit to unlock that location's suggested well depth, drilling suitability category and expected well yield, because depth alone doesn't tell the whole story: a well can be unproductive even where water is present. 1 credit = 1 location, and unlocked locations stay saved to your code so you can return to them.
  4. Get the detailed AI reportincluded with the unlock (no extra credit): a professional, easy-to-read AI report in your chosen language. For ambiguous sites you can add an on-site photo or a short terrain answer to refine the result. Export to PDF or Word.
Watch (2 min): how the depth to groundwater is estimated, and how to gauge well depth before drilling.

What you get

Free

Unlimited quick estimates on the map: depth to groundwater.

Unlock (paid)

1 credit unlocks 1 location: its drilling suitability and expected yield, plus a structured hydrogeologist-style AI report in your language — with regional context, yield scenarios, a clear final recommendation, and PDF/Word export. See pricing →

Who is behind it

Methodology development lead: Prof. Milan Radulović, PhD in Hydrogeology. The estimate combines global open datasets — satellite imagery, digital elevation models, hydrography and geological data — within a hydrogeological estimation model.

Important

All results are rough, indicative estimates based on publicly available global datasets and are not a substitute for a field hydrogeological survey. The decision to drill is yours; the author accepts no liability for drilling outcomes.
