How can you replace sewer pipes without digging up my landscaping?

    As some of the others here have alluded to there is a method of lining existing sewer lines known as "Slip Lining".  It is generally used in public utility sewer rehabilitation programs.  In the municipality I worked at we had contracted with "InsituForm" to reline several miles of older sewer pipe in a multi-million dollar program mandated by state and federal laws.  The process involves reaming and pressure cleaning the existing lines, then inserting a fiber reinforced resin sleeve which is expanded and "cured" with high pressure steam.  The cost of mobilizing the equipment and personnel make it impractical for residential applications.   For a residential application it is far cheaper and easier to have a crew of two or three come out with a backhoe and replace the terra-cotta or Orangeburg pipe with PVC pipe in a day or two.  The disturbance to your landscaping need not be a strip wider than about 24 inches.  Mature shrubs that are removed can generally be replaced if sufficient care is exercised in their temporary removal and grass can easily be resown or re-sodded.

    You could have your sewer line "bored" or "jacked", but is late in the year, and few things are growing, so if you want things to be SIGNIFICANTLY cheaper, dig out the bushes/plants in that area (take a picture first), then when the work is done, but everything back where it was.

      "Jack and Bore" is a method of installing sewer and utility conduits under an existing roadway and is significantly MORE EXPENSIVE than open trench construction in a residential yard.

    Ask "them".  They know the tools they got to put in a pipe liner.  Ask more than one.  Some are just Joe with a shovel.  The other guy is fully equipped with the latest sleeving tech. to do this. They can do oil wells, so a turd pipe is not a big deal or very long.  They also have that machine that made a Tunnel under the English Channel to join Britain with the mainland by the Chunnel.  20+miles.

    My septic is in the back of the house so they ran a pipe up the front of my lawn past the side of the house to where the house septic pipe comes out and disconnect from the tank and connect to the pipe. The sewer pipe on the road was about 15 feet deep.  You almost can't tell they were there.  Mind you that was several years ago.

    afaik, you can't. the sewer leaving the house should go out in a fairly straight line for some feet. That's usually where folk put their landscaping. Since this portion of the sewer line is your responsibility, the landscaping is also your worry and your responsibility. [In my community, the 'usual' design is that the sewer line is under the largest front window and usually within 18 inches of the center of that window. It runs perpendicular to the wall of the house.]

    You might look into having the existing pipes lined, which is done by a machine and requires minimal excavation. But if the pipes have collapsed that is unlikely to be feasible.

    It really is not possible.  To save your landscaping, you might have to consider using and outdoor portable sh*tter.

    First, the can rotor it out, cleaning out all the garbage and branches inside. After they do that they can reline it with a flexible sheath of plastic from one end or the other. All they will have to do is dig a hole at one end or the other. If you have a big enough access pipe up at the house they will not even have to dig a hole.

    There is no ways it can be done without digging up your landscaping.

    IF they run under your landscaping, then you can't.
