Trenchless Tech. Cured-in-place Lining 1

[qaztor]

Hello.
I've read a lot about trenchless tech. to rehabilitate existing sewer mains (Cured-in-Place lining, Slip lining, Pipe bursting). Does anybody know the range of prices for these types of pipe rehabilitation for a 36" sewer line?
The project (sewer main) where we want to consider these options is about 6000 LF long.

Thanks

Trenchless Tech methods vary a lot. Questions that will need answers. how deep is it? Sanitary or storm? water table? under roads? what material is the existing pipe? soil type? Do you want to upsize? access to pipeline? Is there a new use for this line? general area pipe is located? US, state? All these affect costs. If you want to talk to contractors, maybe I know some near this line.

BRIS thanks for the links. Very helpful.

dicksewerrat these are some other details:
how deep is it? < 11 feet
Sanitary sewer, under city street, the existing pipe is prestressed concrete cylinder pipe (some of the concrete core has collapsed exposing the steel cylinder). Access is limited because it is a pressure sewer (not force main)

This line can be rehabbed in about three days. One day to bypass, clean and inspect. One day to line and cure and one day to tear everything down and be gone. Where is this line? Sounds like something we do every day all year long.
