I have looked in the NC but cannot find any information on what is allowed in terms of sharing trenches with other trades; i.. – electrical & plumbing in the same trench. I recall having read something about it somewhere but I can’t find it. Any help?

I'm always willing to help Taunton Press sell a book:

*Common trench for gas & electric services ok
*No sewer in common trench
As usual, check local codes.
*I've been allowed to put sewer in a common trench in some areas, below everything else. Some inspectors (local rules or just personal preference?) want some things above others. Electric above potable water, potable water above sewer. I suppose in case of multiple leaks, during a time of no water pressure to minimize the chance of water wetting the wires or sewerage getting in the water supply. Always seemed odd reasoning to me. Your mileage may differ. Objects in mirror are closer than they appear. Always check locally before breaking ground. -David
