Sharing a trench

This may seem a silly question but, can a plastic gas line and a PVC water line share the same trench? I've got a deal to dig the trench(s) and a plumber buddy will lay the pipe but I didn't ask this question and he's unavailible for a while.

I'm getting ready to run a 1" PE gas line and a 3/4" water line to an addition and this issue is unresolved.

Thanks,
Bugman

We were able to run our well pipe and the electrical service for the pump in the same trench. Of course we had to encase the electrical and keep them 6" apart, but I'm not sure why exactly because it has been about 5 years. In our area, the propane had to be 2' away. Codes may have changed, so it may be a good idea to call the building inspector to find out what they require in your area.

Codes in our area are similar to onourown's.
You can run the water in the gas trench or the the electrical trench.
Just can't run gas and electrical together.

Ask your local plumbing inspector, these codes are strict and can very from place to place.

Inspectors

That's part of the problem. We don't have plumbing inspectors or building inspectors for that matter. You're kinda on your own. Mississippi adopts the Uniform codes but the rural areas really have no enforcement. I just want this done correctly.

It's kinda difficult to get things done properly in the county. I have had to study and ask many, many questions and buy code books along with threatening contractors to get the answers needed for most projects.

Anyway,

Thanks for the replys.

I know under UPC that sewer and water can be in the same trench if both materials are permitted inside the building, but if both are not allowed inside a building then the water pipe must be 12" away for the sewer line in all direction and put on a shelf.

I don't know what the requirements are for gas and water in the same trench.

That code is in the one and two family dwelling code book, which I don't have.

Maybe someone else that uses UPC will be along to give you a definite answer.
