Our Technology
Well Water Finders runs on a patented, non-invasive technology that measures groundwater and depth at a specific site - without drilling or disturbing the land. Here's how it works, and where it came from.
How It Works
The survey is a reading, not a dig. Our patented system sends electromagnetic signals into the ground and interprets what comes back - then measures groundwater location, depth and potential volume across the acres you survey.
Send the signal
Equipment at the surface sends electromagnetic signals down through the ground. No drilling, no trenching, no disturbance.
Read the response
Aquifer layers return distinct signatures. Our patented system captures and analyzes those signals in real time.
Measure and map
We measure groundwater location, depth and potential volume at the surveyed coordinates, then deliver a report mapped to landmarks on the property and exact coordinates for your driller.
Built on a patented foundation
Well Water Finders didn't start with groundwater. It started with a family legacy of detection technology.
Electrical engineer Franz Vandekop built the first solid-state over-the-horizon positioning system - technology deployed by NOAA, the military, and the oil industry before GPS. Working with his son Andrew, a robotics engineer and the company's CEO, the two adapted that detection expertise to groundwater, earning a U.S. patent on the method after years of field testing across diverse terrain.
U.S. Patent No. 10,830,915 B2
A method of determining subsurface properties using multifrequency electromagnetic depth sounding - plus a patent-pending next-generation system.
Verified accuracy
Across the wells drilled after our surveys, our technology has found groundwater with 90%+ accuracy - measured by how often the depth and location we detected matched what the driller found.
What the technology can't guarantee is the well itself. Drilling outcomes depend on factors beyond the survey - local geology, nearby wells drawing down the aquifer, drilling technique, and pumping equipment. The survey gives you the best data available to make a drilling decision. It doesn't replace the drill, and it doesn't control the variables that come after.
And because better-sited wells mean fewer dry holes, the payoff runs three ways: better for budgets, better for equipment, and better for the long-term water picture.
What's next: TunnelHawk™
In 2025, Well Water Finders filed a patent-pending application for TunnelHawk - a next-generation sensing system built on the same electromagnetic foundation.
TunnelHawk extends the technology beyond groundwater, with the ability to detect underground features like water leaks and structural risks - opening new applications in infrastructure resilience and resource conservation.
