Video Pipe Inspection Services To Locate Sanitary Line

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

After removing the cleanout cap, GPRS was able to visually see the direction and material of the sanitary line in question. At this point, GPRS provided the client with the first depth measurement utilizing a tape measure down to the bottom of the 90-degree fitting. The Project Manager then inserted the ridgid push pipe camera and was able to confirm that the line was only going in one direction from this clean out. After a couple feet into the sanitary line GPRS was able to visually see two taps/laterals and marked their locations at the main. The pipe camera was pushed another 10 ft and then provided another mark on the floor in crayon – noting the pipe location. At this location the PM took an approximate depth measurement with our Radiodetection 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 ridgid 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 line, and last the customer now has the location of the sanitary line for their sawcut. They mentioned to GPRS onsite that they took a chance on exploratory digging on a previous job but did not find the target line 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 pipe 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 sawcut.
