Video Pipe Inspection Services To Locate Sanitary Line - Seattle, Washington
GPRS video pipe inspection services were called out to a
school in Seattle, Washington to locate a sanitary line for a local
mechanical contractor. The client is performing renovations 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 and begin the assessment. 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 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 / sewer line GPRS was able to visually see two
taps / sewer laterals and marked their locations at the main. The sewer pipe camera was pushed another 10 ft and then
provided another mark on the floor in crayon – noting the pipeline location. At this location the Project Manager took
an approximate depth measurement with our Radiodetection 8100 pipe locator and noted it on the floor and sketched for
the customer. This process helps the customer in multiple ways; first by utilizing the sewer 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 sewer pipeline investigation was
performed, we provided the customer with a Blue Beam sketch documenting / assessing 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.
The GPRS Video Pipe Inspection team is ready and equipped to handle any of your
pipe inspection needs. We have multiple different CCTV pipe cameras to handle most situations. This includes various
push cameras that can fit into pipes that are above 1’ ¾” in diameter. GPRS also utilizes the Envirosight Rover x
mainline and Rover x Sat lateral launch camera to prevent and locate cross bores.
Video Pipe Inspection Services of Sanitary Sewer System - Seattle, Washington
Recently GPRS was called out to a job site in Seattle, Washington for an inspection of their sanitary sewer system.
sewer inspection and assessment took place over the course of six days. While working on-site GPRS closely followed
safety regulations, including wearing proper PPE and coming off the area of work to keep pedestrians safe. During our
pipeline inspection we used our Robotic crawler camera (CCTV) to inspect the main sanitary pipelines as well as our
push camera when the robotic crawler was not feasible. Our robotic pipeline and sewer cameras come equipped with a
sonde that allows us to pinpoint any locations in the pipe including at laterals that are cause for concern. This
makes it easy for any excavation crew following up after us to dig in the correct area, saving them time and money.
Directly pinpointing the problem area avoids unnecessary digging for our clients. We also coordinated with a local
pipeline / sewer jetting company to help clear out any pipes that were unable to be inspected due to debris build up.
This ensures the client gets the best results due to a clear and visible sewer pipe for reporting. Over forty
individual sections of sewer pipe were inspected over the duration of the project. Along with sewer camera video, the
client also receives a detailed NASSCO report and assessment for each sewer pipe including damaged sections inspected.
They are also provided with a detailed sketch of the scope of work, that serves as a visual aid to accompany the
video, so the client knows exactly what section of inspected pipe they are viewing.
GPRS runs the sophisticated
Envirosight RovverX Sewer Inspection Crawler; with six-wheel drive, 12 quick change wheel options, and full pan and
tilt 360-degree inspection pipeline camera. The RovverX is considered the workhorse of inspection robots. GPRS can
fully inspect sewer mainlines, sewer laterals, and pipe manholes. We conduct lateral launch sewer
inspections, cross-bore-mitigation, sewer and water inspections, water and sewer mapping and manhole inspections near
Seattle, Washington. We provide detailed mapping and video inspection
files. Our project managers are training in pipeline assessments, lateral pipe assessments and manhole
GPRS is a nationwide utility locating service serving Seattle, Washington with experts in underground utility locating, concrete
scanning, and video pipe inspections (CCTV). For more information about GPRS capabilities or questions on how we could

GPRS Performs Video Pipe Inspection of Sewer and Storm Lines - Seattle, Washington
The sewer and storm lines at the
Fashion Center Mall in Seattle, Washington, were a mess. The stores in the mall opened and closed and
leases were signed and broken due to the roller coaster of events that was the pandemic of
2020. The old Nordstrom building, in particular, had significant problems with the sewer
and storm lines backing up and not draining correctly.
Ground Penetrating Radar Systems (GPRS) was called out to perform a video pipe
inspection of the sewer line to diagnose the problems. Using CCTV, GPRS Project Manager,
Arthur J Formoso, responded from the Seattle, Washington, location, with the help of Area Manager
At the site, they began to inspect the integrity of all sewer and storm lines
ranging from 18-inch to 24-inch diameter lines. They lowered a robotic crawler camera down
the main line, recording a video of what they found. The rover-type sewer camera they used
can crawl up to 1,000 feet into a main line and perform video inspections.
During the inspection, they found gravel obstructions and some areas where the
pipe had completely collapsed. As a result of the video sewer inspection service, GPRS was
able to find, inspect, and provide NASSCO-certified documentation so the property owners
could make the necessary repairs for future mall tenants.
GPRS offers many different subsurface inspection services including manhole
inspections in Seattle, Washington, cross bore locating in Seattle, Washington, storm inspections in
Seattle, Washington, sewer pipe locating in Seattle, Washington, and sewer lateral video
inspections in Seattle, Washington.
