(OP)
Does anyone know if there would be any problem with putting gas, electrical and water line in the same trench?
I would think there would be a problem with water and electrical in the same trench but not sure.
Thanks

With electric on the first bench, then gas on the second and water the deepest.
One problem you may run into is with the gas company who will own the line. If it is a high pressure line they wont allow this, if it is a low pressure distribution line they probobly won't mind.
As long as each line can be excavated in the future without impact to the other lines.

Watermains are usually deeper than power cables to avoid freezing. Where I come from water mains are usally 900mm down power cables, 450mm unless particularly high voltage.
RE: In trench utilities
This is for our provincial parks so we own the secondary line we put in, plus it is going to be low pressure.
We rarely have a gas leak or electrical problem but have lots of water breaks. How would you excavate that utility trench to get at the water without impacting the other lines using your standard detail?

RE: In trench utilities
Sounds as if you are alluding to possible water pipeline corrosion from stray currents from the electric line affecting the water line. I'm definitely not an expert in this field but it's wise to be concerned. Are there any forums here that have corrosion engineers?
BigInch, aren't pertroleum pipelines often concerned with the possibility of this type of induced corosion? Maybe you have some guidance on this aspect of the issue?

There is a corrosion forum where you can probably get
