I have a house that I think needs to have the septic system replaced.

If you are anywhere near civilization you will likely be mandated into
installing a raised, sand-mound sysem. It will be partially raised above
the existing ground level and toppe with topsoil and seeded with grass
*only*. It allows the effluent from the tank to escape into the sand and,
because it is raised, evaporate rather than sagnate. Pretty expensive
project. Get ready for sticker shock - sorry.
