Here's a good one for you. I just got a call from a client on a out of state project I did last summer. It's a vacation home in WA. The utility company phoned her to say that there is water coming out of the meter base.
I asumed that they meant the water was coming out of panel. I told her to call the contractor that put in the water pipes that were in the same trenches as the secondary conduits.
The well contractor went out to the site and determined that the water was actually bubbling out of the ground below the meter panel. Appearently the roughly 500 feet of trenching were acting as a "french drain". The meter location is at the lowest elevation on the property and the water from the 5 acres must be channeling to the trenched areas, soaking thru the clay soil (which doesn't hold water), into the sand bedding around the conduits, and making it's way down to the end of the trenches at the meter and coming up to the surface. The trenches were all backfilled and compacted well.
The main trench from meter to the home site closely follows the natural drainage path .
Has anyone ever seen anything like this before, and if so, are there any solutions to resolve this besides reworking site drainage in general?
I guess we could turn it into leach field for the septic system when ready. Is there anything in the code against having conduits in leach field? (Joke!)
