From Drain Spotting to Drain Inspection

For some people, a drain is a thing of beauty. Sheffield has its own self-confessed drain spotter, who spends his time looking for rare sewer covers.

As part of a local preservation group, he works to retain public heritage features, including covers that date back to Victorian times.

While we can appreciate the detective work and attention to detail, our own work involves a different kind of drain inspection, including drain tracing, CCTV drain surveys and dye testing.


What We Need to Know

Admiring and studying drain covers is one thing, knowing where the drains actually run to is quite another. With construction projects, for example, it is often of vital importance to know sewer and drain network locations, because damaging an existing drain can have serious implications in terms of both time and expenditure.

The plans that are available giving details of the drainage network can often be out of date, particularly when you think that some drainage systems date back to Victorian times, hence the vintage drain covers.

It’s important, therefore, to have fully up to date knowledge of the drainage network.


Drain Tracing in Action

Finding where drains run to underground requires a degree of professional detection expertise, which is where our drain tracing services come in.

We have a range of drain tracing procedures we can employ, depending on the complexity of the individual situation.

Our main drain tracing technique involves the use of sonar. Here we transmit electronic pulses which enable us to take accurate readings about what kind of condition the drains are in, and where they are located.

Hand in hand with sonar drain tracing is our use of CCTV. We can send cameras down the drainage network in order to record the interior state of the pipework in a drain survey. This can help us identify problem areas and issues prior to undertaking any physical exploration work.

We also use a process known as dye testing for drains. This involves using a non-toxic liquid dye to indicate where there are leaks and blockages in the drain. It’s also useful in situations where we need to test how well the drainage system is connected. We can also use different coloured dyes for different sections of drain.

Drains may be a source of fascination for some, and frustration for others. For us, they’re our speciality, and we’re here to make sure they work properly.
