THE BOTTOM LINE
GPRS paired specialized equipment with our industry-leading sewer pipe inspection process to locate a sewer line hidden 40 feet below the campus of the 124-year-old Carnegie Mellon University and ensure the safe installation of a foundation for a new building.

PROBLEM
- Existing as-built documentation indicated that a sewer line ran through the planned location for the new building’s foundation, but the contractor had not been able to locate the line themselves
- The sondes (instrument probes) built into GPRS’ sewer inspection rovers can only locate sewer lines up to 15 feet deep
- Due to the hilly conditions on campus, the sewer line was presumed to be located deeper than normal
Solution
- GPRS Project Manager deployed a Prototek Durasonde ‘super sonde’ Transmitter, which is locatable in nonmetallic pipes over 50 feet in depth
- Sewer pipe was located, and location and depth were marked on the surface using spray paint, so project team knew where they could and could not dig
- Data was uploaded into SiteMap® to document sewer line’s location for future O&M purposes
Benefits
- GPRS helped prevent subsurface damage that could have otherwise derailed the project and led to service interruptions
- Documentation of the line’s location and depth in SiteMap® will streamline future O&M
