Private Utility Locating at Fish Hatchery

Ground Penetrating Radar Systems (GPRS) was contacted by a fish hatchery in Southern Illinois to come out and locate private and public utilities for running new communication lines underground. After scanning for a couple miles, we were able to confidently direct the electrical contractors away from hitting any utilities while trenching.


This particular fish hatchery has supplied over 500 million fish throughout its years of operation. Fish hatcheries in Illinois are also very important as they supply Lake Michigan and many other surrounding lakes with fish in order to keep up with the growing rate of recreational fishing.

“Time is a primary currency traded on any given construction project. At Ground Penetrating Radar Systems, our everyday efficiency in operations allows us to respond to the immediate needs of our customers, often within 24 hours or less.” (

Scan before you plan! This ensures worker safety and saves valuable time by targeting specific areas of concern. GPRS can also provide GPS reports overlaid on Google Earth or overlay information on pre-existing CAD files for future building plans. This is all done in a safe, time efficient, non-destructive manner.

GPRS assists by giving a real-time depth view of subsurface hazards such as reinforcing, utilities, conduit, underground storage tanks, voids, etc. This reduces the likelihood of subsurface obstruction strikes during core drilling, saw cutting, trenching, soil boring, directional drilling, anchoring, and other sub-surface applications.

Ground Penetrating Radar Systems uses the GSSI (Geophysical Survey Systems, Inc.) Sir-4000 technology in locating. GPRS also uses the RD-8100 Locator to locate live power and radio frequency (RF) signals underground. We can also detect utilities in or under concrete via induction or conduction with an exposed or known surface utility line.
