Sewer line replacement can seem like a huge expensive ordeal but it doesn’t have to be.
Newly constructed lateral sewers made to connected to existing public main sewers require excavation and digging in order to place the sewer lateral pipes underground.
Traditionally, when replacing a sewer line, excavation is needed to dig up the existing sewer pipes remove them and replace them with new sewer pipes. This method of replacement includes added costs for the excavation, whether by machine or by hand, and reconstruction of any landscaping, decks, concrete etc. that was built over the sewer line.
Sewer Line Replacement by Excavation or Trenchless
Trenchless rehabilitation can save you a lot of money on sewer replacement as it incorporates all or part of the existing sewer line structure to improve the performance of the pipe. These methods often do not require any excavation as the existing sewer path can be use to put in a new line to replace the old one, either by relining or pipe bursting methods.
Either way, you won’t have to dig up the old sewer line, saving the cost of labor and of replacing any topography above the sewer line like decks or landscaping.
There are a variety of trenchless sewer line replacement methods to restore the performance of the existing sewer line rather than construct a new sewer line to serve the same function.
- Pipe bursting – Pipe bursting is a method of inserting a new pipe inside the existing pipe which causes the splitting or bursting of the existing pipe to make room for the new pipe. The broken pieces of the old pipe remain in the ground.
- Slip lining – Slip lining is a method of inserting of a new pipe inside the existing sewer pipe and the space between the pipes is then grouted.
- CIPP – Cured in place pipe lining is a method of inserting resin tube into the existing pipe which is then inflated so it expands to lay flat against the inside surface of the existing pipe and is then cured in place covering over any cracks or other breaks in the pipe.
