Is it a good or bad idea to lay or run a french drain over spectic lines. It would be appoximately 8" deep and run perpendicular to the septic lines which run 24" deep.
Or, how about just a drain line without the perferation to move a little water to a more desirable location that would run above the septic line in a similar way?

If you DO cross the leach line alignment, by all means do use just strictly "transportation" pipe and not perforated. [img]/forums/images/icons/tongue.gif[/img]
