Drain Sewer Pipe CCTV Survey ServiceBecause drains are largely hidden from view, the exact cause and nature of the problem may not be immediately apparent. That`s why inspection and diagnosis are crucial features of D&L Drainage service`s. With the passage of time and usage, drains and sewers can deteriorate. It may take several years, but drains can suffer as a result of many factors such as ground movement, poor construction, tree root invasion etc.The D&L Drainage CCTV survey is specifically designed to investigate a drain`s condition for the following reasons: Problem Solving - Sometimes, nothing less than a visual assessment of a problem will meet the need. In such cases, television provides the full picture. CCTV surveys of drains, pipes, and sewers provide an accurate and cost effective way to detect problems to the source and help establish the most practical remedial options. Problem Prevention- When problems with drains or pipework are to be avoided at all costs, CCTV enables potential faults to be identified before they become a problem. The CCTV Surveying ProcessA CCTV Survey can be carried out with the minimum of fuss and disruption. The process is as follows:
STEP 1 Camera Inserted into Drain.The CCTV camera is introduced into the
drain via the appropriate access point and pushed or powered through
the pipe STEP 2 Operator Observes & Records. As the camera travels along the
pipe, the image is relayed to a monitor screen above ground. The
operator will then log any structural defects and record the location
of each along the pipe length STEP 3 Survey Report Provided. The survey report is then provided
which lists the type and location of any defect. This can be backed up
with photographs, video or CD evidence together with a site plan
showing the drain`s location.
