Dana, bury the conduit below frost line, whatever that is in your area, and to code. Then when you filling the ditch, about 18" form the top lay 4 or 5 strands of red or yellow plastic flagging tape the length of the ditch. Then cover it all up.
In the future if anyone ever digs in that area with a hoe or excavator, they will dig up the plastic flagging tape warning them before they rip up your lines. Most excavators know if they dig up flagging to use extreem caution.
All my underground is marked that way, drains, power, water etc.
