Driving over septic system

    Hi,

    I need to take down a large tree in my backyard where the only way to
    do it is either through a climber (very expensive) or by bucket truck
    (much cheaper and I liked the owner). $2,000 vs $600

    The main issue is that there is no way to avoid crossing the septic
    system. Mine is about 45 years old.

    I once heard you can't drive over any part of the septic system. What
    he plans to do it to use ground protection mats to create a path to
    the tree. He says it is not good to drive directly over the tanks,
    but it would be fine to go over the pipes using these mats. In
    particular this would be the pipe between the house and the tank (not
    the leach fields). I estimate the pipe is buried only about a foot
    and a half. He says that because of the round shape it can take a
    great deal of pressure without breaking.

    This is a site with mats like he is describing:
    http://www.alturnamats.com/

    Does this sound ok and safe to do or should I go the more expensive
    route and get a climber?

    Thanks,
    Steve

    No problem as long as he doesn't put the truck _in_ the tank--the lids
    are not designed to support that kind of load. I wouldn't worry too
    much about the drain field for a (relatively) light truck, either, for
    a field that has been in place that long as long as you don't do it
    during a period of wet weather. That's not to recommend driving around
    all over it, but a single track in and out during dry weather w/ a
    truck that won't be more than say 5-6000 lb isn't likely to be a major
    problem. If he were to start cutting obvious ruts in the area when he
    started in, that would be a bad thing (TM) :), but w/ the load
    distribution mats I wouldn't worry much at all...

    I used the 10" round black plastic pipe (very similar to septic pipe)
    as drain pipe under my drive. It's buried about 16" deep. Then I had
    loggers cut 20 acres of pine on the back of my property. They drove 18
    wheelers loaded with logs across the drain pipe in the drive and never
    damaged it. So yea, that round pipe can take a lot of pressure.

    get a estimate on a new septic system then decide if the savings are
    worth the risk.

    My leach field is on the other side of my driveway from the house. About
    thirty years of all kinds of trucks, including garbage trucks driving across
    the pipe from the tank to the field (gravel driveway) hasn't hurt it.

    If this is the single line from the house to the septic tank and it is only
    18 inches deep it is worth a little investigating. In an area that the truck
    will NOT drive over, dig down to the pipe. Be careful because 45 years ago a
    lot of clay pipe was in use and it will be brittle. If the pipe is cast
    iron, you should take care because stress can crack it and the 5 foot
    lengths will add to its fragilness. If it is vitrified clay (glazed clay) it
    can shatter under the load, do not let him drive over it unless you are
    prepared to replace it. If the pipe is black fiber "No-Co-Rode" pipe, it
    probably will hold up as it has a little bit of play. If the pipe is black
    polyethylene, you will have no trouble. I cannot think of any other types of
    pipe in use 45 years ago. If the best intentions fail, and whatever pipe you
    have fails, you should be able to easily replace it with modern 4" PVC sewer
    and drain pipe.

    How do you figure a foot and a half? Is your tank sticking up
    out of the ground or something?

    IME, it's OK to do. Did you ask him what he'll do if he does
    crush it? You might like the answer. If not, ask a couple other
    contractors and compare answers. Many know what they're doing, a
    few don't of course, but that's part of what they're being paid
    for.
    It shouldn't be a problem, really.

    If you're the grudge type, get the climber out there.
