CCTV Video Camera Pipe Inspection

GPRS Conducts a CCTV Video Camera Pipe Inspection in Oklahoma City, Oklahoma

Ground Penetrating Radar Systems’ (GPRS) video pipe inspection services were called out to a school in Oklahoma City, Oklahoma to locate a sanitary sewer pipe for a local mechanical contractor.  The client is performing renovations to some classrooms and needed to know where the sanitary pipe was located below the slab and had a visible clean out in their construction area.  Our client also requested the approximate size and depth of the sewer line to determine if they could utilize this pipeline or if they needed to search for a different location to tie in.  

After removing the clean out cap, I was able to visually seethe direction and material of the sewer pipe in question.  At this point, I provided the client with the first depth measurement utilizing a tape measure down to the bottom of the 90-degree fitting.  I then inserted the ridged push camera and was able to confirm that the pipe was only going in one direction from this clean out.  After a couple feet into the sanitary pipe, I was able to visually see two taps/laterals and marked their locations at the main.  I pushed another 10 ft and then provided another mark on the floor in crayon.  At this location I took an approximate depth measurement with our Radio detection 8100 pipe locator and noted it on the floor and sketch for the customer.  This process helps the customer in multiple ways; first by utilizing the ridged push camera we were able to see that there were laterals inside the work area that the customer could use to tie in his new sink, second by providing estimated depth measurements, the customer was able to calculate if they would have enough pitch to tie into this sanitary system, and last the customer now has the location of the sewer pipe for their saw cut.  They mentioned to me onsite that they took a chance on exploratory digging on a previous job but did not find the target pipe they were looking for which wasted them a lot of time and money.  After the onsite investigation was performed, we provided the customer with a Blue Beam sketch documenting our findings.  This sketch included the approximate size and depth of the pipeline which the customer could confirm with a test hole.  Further utilizing our services our GPR team were scheduled to follow up behind us to let the customer know if there are any conflicts in the concrete slab for their saw cut.
