Can electric and water utilities be in the same trench? And if they can what is the seperation allowed and can the electric conduit be laid over(on top of ) the water line?

Re: utilities in trench
What do you mean by utilities?
There is no code restriction I can think of that restricts electrical systems to be in separate trenchs from other systems. There is also no specified separation requirement.
When you say utility, I think service entrance. Most likely the POCO will not permit the service lateral to share a trench with another system. At least the ones in FL don't.

Re: utilities in trench
My PoCo dictates those rules mostly.
Sometimes it's hard to dig a bunch of parallel trenches. On the surface it would seem that you could dig one wide trench that would fulfill all the spacing requirements for the various utilities; stake of the conduits and pipes; put some tracers in the trench; backfill with sand.
But, many will not allow trench sharing no matter how wide or deep your trench is. Sometimes with sharing they make you dig "shelves" for the shared conduits/pipes and put the big conduits/pipes in the bottom of the trench.

Re: utilities in trench
Once a trench is closed, is width such an issue? For arguments sake, the ground when closed does not know how wide the trench may have been. The POCO here will permit utilities in the same trench as long as a width separation that they require is maintained. The service conductors on top of the water is not permitted.

Re: utilities in trench
The conduits I am talking about would be a electric utility secondary. And also a conduit for some lighting (branch circuit)The water line is 6' deep and while the trench was open we wanted to use it so we wouldn't have to dig another trench. This is a road crossing that was previously paved.

Pierre: That's what I'm getting at
Once the trench is closed three trenches become no trenches, and one trench becomes no trench. There is no difference if you start with three separate trenches or if you start with one big wide trench for everything.
Thank you for distilling my answer down to its element. In the end you end up with no trench.
