Underground electric/drainage question

[lman]

I was not concerned about water getting into the PVC. I know it eventually will. I just wanted to help drain the area where the electric line will be, just had a free trench to do it in the right location. The farm drain tile would be to dry up the ground above, nothing to do with the PVC electric line other than the same trench.

Sounds good as long as the electric company doesn't object.

In my area in Central Texas, the power company required an easement to run from the transformer, located on the road side powerline to the meter at the house. It is a buried line 810 feet long, 36" deep, using 4" PVC conduits. I requested metal conduits, but was informed I actually have little say over the matter, since the power company will own the line from transformer to the meter. And that's the way it should be, because any transmission loss along that 810 feet is on the power company and not the end power user.

The easement was a 5 page legal document with survey attached, filed at the local court house, defining the easement as 810 feet long by 10 feet wide and listing my responsibilities as surface owner to maintain brush clearance, and prohibits any digging along the easement without prior notification to the power company.

Why didn't you just run the high voltage primary to grade mounted transformer closer to the house.
Much smaller wire, smaller conduit and less voltage loss.
What size wiring did you run in that 4" conduit 600MCM.

Zero reason to put tile above it below. Put the cable in the pvc and bury it. Done and per code

So, I have actually read through this thread... (not saying other haven't... but they haven't)... We also have this working... Our driveway is a little over 1/2 mile long & our power is on poles for 2/3's of it, then the power goes underground to the house. Because the slope of the land, the woods & our driveway we have drainage pipe installed above our our electrical (direct burial) cable. It is not there to remove water from around the cable; it is there to remove water that would saturate that part of the ground from ground water (& literally... oh, & physically, sink a vehicle driving past... yes not over... past). The drainage pipe runs along about a 200+ foot sections & connects to a drain distribution box, that also has a surface grate that the driveway pitches to, which then diverts the water under the driveway to the opposite side to daylight. It works flawlessly & keep the ground from being a sink hole.

I know some will worry about the... what if you need to dig for a repair... First the odds of digging up your electrical service in your lifetime would mean something pretty serious & having to fix a little bit of drainage will be miniscule to whatever caused the power issue... (even if you dug a wider trench odds are the drainage will be effected by the excavation for the repair)

Just make sure you check with your power supplier & the local inspectors... Our had no issue with it & it has worked... Oh, & ours was a retrofit to fix an issue that already existed prior to us buying the property.

Except if you would actually read.....he is wanting drainage in the area to dry up a wet spot. Has nothing to do with electrical....other than the possibility of sharing the trench since it's open

From the transformer an underground electric line is going to be ran to the house. It will be in 4 inch schedule 40 PVC. It needs to be at least 36 inches underground. The area it runs tends to get wet. After the electric line is it reasonable above the PVC to place a 4 inch perforated plastic farm drainage tile? I would already have the trench open and could easily place the farm drainage tile in and connect to other tile to help drain the area. I could put some fill material between the two.

Typically drainage comes from the bottom up on drain tile pipes, not as much as from the top down. Hence, the reason for putting drain holes down (single side/hole) or sides (2 side holes). This said, the conduit would be sitting in water anyway.

Typically, crushed rock (without fines - I've used 1/2- in the past) is under the conduit. I've also used PVC pipe wrap around the joints - not typically code, but cheap insurance.

This is hilarious. Out of all these answers only about two or three people actually understood the question. Poor OP.

So you offered this.
