Where is Trenching Used?

April 10, 2011

Last weeks blog talked about what trenching is used for, so today, let’s discuss where these trenches are being used.

Generally speaking, trenches can be used to protect the underground distribution of such things as fiber optics and mechanical piping, but more often than not, we are protecting electrical wires that are required to move the power from some type of generating source (such as a generator at a hydro dam) to a point where that power is being diverted and/or transmitted (such as a swithgear building). This underground transmission typically ends up exiting the ground and continues it’s path, eventually to your home, through such traditional means as along the hydro lines we see beside most of our country roads and highways.

So, we are typically making trenches for substations where they are harnessing this power and converting it to a more usable form by the consumers.

Here is what a typical installation looks like:

Not all trench ends up on a substation site. This last summer we had a request for some trench that was much bigger than the standard sizes we typically make. We were asked to supply trench to a site in Northern Alberta where big pumps were required to move water through large 24″ pipes for about 30 km (about 20 miles) overground. We met the challenge and as I write this post almost all trenches have been installed.

Here is a picture of a small portion of the trench in ground:

I hope you get the idea of why companies use trench. The one benefit it brings to the customer that is really essential to them is the ability to access these cables/pipes/fiber optics quickly. As you can imagine, a lot of people are relying on the consistent source for their power, so if there is a failure, they need to fix the problem immediately. By having the removable lids easily accessible, they can be lifted quickly and the faulty unit repaired or replaced without having to worry about digging into the ground and possibly cutting the lines as they try to access them.

I hope this clarifies for you why people need our trenching. If you have any questions, please e-mail me at info@barkmantrenching.com and I will be glad to answer any question you may have.
