Lost Manhole Mystery: Sewer Inspection w/ Metal Detector and EM-61 Plan | multiVIEW Locates Inc.

Welcome to another intriguing episode of our sewer inspection series! In this video, we delve into the challenges of locating a lost access manhole buried beneath thick, uncut grass. Join our skilled technicians as they tackle the problem using a basic metal detector, and discover why a Geonics EM-61 time domain electromagnetic device may be the key to solving the mystery in the future.
Introduction:
In today’s episode, we face an unexpected obstacle during a routine CCTV sewer inspection. Our goal was to inspect the sewer system, but we encountered a significant issue: the access manhole we needed was lost and buried under a dense layer of uncut grass. The episode showcases the complexities involved in such situations and the tools used to overcome them.
The Situation:
When our team arrived at the site, we were ready to commence the sewer inspection. However, we soon realized that locating the access manhole would be more challenging than anticipated. The manhole lid, which is typically straightforward to find, had become obscured by overgrown grass that had not been cut in a long time. This made it nearly impossible to identify the exact location of the lid using visual cues alone.
Using the Metal Detector:
To tackle the problem, our technician employed a basic metal detector. This tool is commonly used for locating metal objects underground and seemed like a good starting point. The video captures the technician’s meticulous approach as he sweeps the metal detector over the grassy area, carefully searching for any signals that would indicate the presence of the metal manhole cover.
Challenges Faced:
Throughout the video, we highlight the challenges of using a basic metal detector in this context. The thick grass and potentially irregular depth of the manhole lid made it difficult for the metal detector to provide clear and accurate signals. The technician’s patience and methodical approach are evident as he attempts to adjust the detector and interpret the signals.
These insights are valuable for viewers who might encounter similar issues in their own inspections.
The Technician’s Recommendation:
After an extensive search with the metal detector, the technician concludes that while the tool provided some useful indications, it was not sufficient to pinpoint the exact location of the manhole lid. Based on the difficulties encountered, the technician recommends using a more advanced piece of equipment in future visits.
The recommended tool is the Geonics EM-61 time domain electromagnetic device. This sophisticated device is known for its effectiveness in detecting metal objects buried beneath various materials, including thick grass and soil. The EM-61 offers greater precision and depth capabilities compared to basic metal detectors, making it an ideal choice for locating buried manhole covers.
The video provides an overview of the Geonics EM-61, explaining its operation and advantages.
Future Plans:
As the video concludes, we outline the next steps for resolving the manhole location issue. We plan to schedule a follow-up visit equipped with the Geonics EM-61 to accurately locate the buried manhole lid. This future inspection will be documented in a subsequent video, providing viewers with a detailed look at how the advanced technology performs in practice.
Conclusion:
Thank you for joining us on this journey through a challenging sewer inspection scenario. We hope this video provides valuable insights into the difficulties of locating buried access manholes and the tools available to overcome these challenges. Stay tuned for our next video, where we’ll use the Geonics EM-61 to find the elusive manhole lid and continue our exploration of sewer inspection technology.
