We specced safe-trace with 1800lb pullback strength for our current project and
will likely makenthat the standard for anything drilled in moving forward. Not
sure it is overkill.

14 gauge is rugged and will last. I think the gas company out here uses 14
gauge. 20 gauge on up is not terribly strong. UDOT recently changed their
spec for the tracer molded into MD7 microduct from 20 gauge to 14 gauge.

Don't you have some random copper laying around? Our fiber tracer wire is 24
awg. Just place the conductive wire in the same hole as the water/sewer lines.
The color is kind of pointless but I guess you could spend the money and
follow the rules *shrug*.
If the wire ends the locate ends. Why not just extend the wire with the new
pipe?
14 gauge seems like way too big if you ask me, that's a lot of money down
that new sewer line.

I'm working on doing specs for a project (home) which will require burying
new water and sewer lines on the property.
I'm tired of not being able to locate these after they're buried so I plan
on having the contractor bury some tracer wire along with the plumbing.
I've learned that the best option for things like this is to either spec or
provide exactly what I want buried. Otherwise you'll end up with some
inexperienced contractor which installs something which won't work.
Apparently the choices for tracer wire are far more varied than I had
expected. Insulation, metal type, gauge, color, and so on.
It looks like 14AWG copper HMWPE might be what I'm looking for. But there
are other options as well. Does any of this work better or is less (or more)
likely to be damaged in a way which makes it untraceable? I'm assuming green
and blue will be needed for sewer and water.
I don't think the following will apply, but there is also the possibility
that at least one of the lines won't terminate at one end anywhere that we can
poke the wire up above the ground (tapping into existing line) I'm assuming
that one can resolve this by laying a ground rod in the trench and terminating
to that.
Any other things I should watch for here?
