Who would have thought that? The old china clay drainage systems that I was involved in back in the day, easily detectable. Theres certainly no system over here to my knowledge that will detect waste/sewer pipes and gullys of that nature.
Drainage has more clues on the surface that other services. It's easy to open manholes and put dye down the one at the top of the run and see which manholes it passes. And you can mostly assume that it's going in a straight line.
Cheers, you can be quite ruthless at time!Midday today ...
What you do is run a line called a flexi-trace down the pipe. You then plug that in to a ‘genny’ and the ‘cat’ detects the electric current in the trace, hence it’s a relatively simple task to map drainage runs.
No you can’t! You’d be surprised how many drainage runs have kinks or curves in them!
Is that a request to pipe down?
Think he means the thread is getting watered down.
