Drains are hidden underground, which is fine when they are working, but inconvenient when they are not. If we need to discover the source of a drainage problem, we have to first be sure where the pipes are located, and what path they take.
This is where drain tracing is such a valuable asset.
What Direction Do Your Drains Take?
Sometimes the existing drainage network plans fail to provide a complete picture. Some drains are old, dating to Victorian times, and over time there have been additions made but not accurately recorded.
This means the plans are not reliable. This doesn’t just affect when we need to identify problems. If there’s going to be building work over existing utilities, it’s vital to know where drainage and sewer pipes are located.
Builders and developers need this information, otherwise they can risk costly and disruptive mistakes that will set their projects back thousands of pounds.
It’s best to be prepared. Using sonar technology, we can trace the pathways of drains and discover where areas of disturbance, damage and deterioration are.
Sonar is essentially about building up a picture from the use of sound. Using state-of-the-art equipment, we send a transmitter into the drain. This will read the inside of the drain using electronic pulses, or pings.
Above ground, we have a receiver to read the pings. Here we are making the use of echo as a way of locating features inside the drain.
Typically, we will have CCTV footage of the drain to give us an idea about its overall condition. Now the sonar lets us accurately pinpoint the location of trouble spots, hidden chambers and manhole covers.
Using this data, in conjunction with the video record, we can build a more detailed picture of the drainage network without having to conduct any exploratory excavations.
We may also use dye testing to confirm or clarify the route that liquid is taking once in the system.
All this enables us to prepare remedial work without having to factor in potentially expensive exploratory work. This makes drain tracing a cost effective means of drainage diagnosis and knowledge-gathering.
