I might suggest adding a marker underground when you close in the trench.
When I ran conduit water lines from the well, and electric lines between
the house and the barn and
hamshack the trench was 5 feet deep. First water pipe, then dirt, then
electric and adding
another foot of earth.
We then ran a red plastic marker "Buried Electric" the length of the
trenches (400 feet). The marker
has between 1 and 2 feet of earth on top. The hope is, sometime in the
future the electric or water isn't
severed, and a bad thing happening when an uninformed person digs a
trench uncovering the marker
first.
Available at electrical supply houses, similar to the yellow "Caution"
tape used at construction and
accident sites
Good luck, we're all counting on you ...
