Asbestos Cement Sanitary Sewer
(OP)
Does anyone have an idea on the typical lifespan of an AC sanitary sewer. Sewer is 6" and has been in service since 1974. Any good publications on this issue?
Thanks in advance.
Thanks in advance.

Therefore, I agree with cvg; make an inspection of the interior. If it is in good condition leave it alone. If not, perhaps it can be relined in place.
If relining is not practical, I suggest abandoning it in-place with a replacement line installed nearby (if possible).
Because of the necessary and expensive procedures needed to handle asbestos based products safely, disturbing or removing it should be a last resort, IMHO.

A sewer service that was built that long ago probably has numerous leaking joints and is probably in need of repair/replacement.
As CVG posted, the best method to inspect the pipe is to use a remote camera at a cost of several humdred dollars.
If the service is not extensively damaged, then you may line it or replace it.

BIMR, I was inspecting clay and PVC pipe for sanitary lines in the 70's. Never saw one installed made of AC. That is not 'along time ago'. The pipes I worked on that were installed in 1880's was a long time ago.

AC pipe was first used in the 1930's. In the mid 70's about a third of the pipe being installed was AC pipe. AC pipe was never banned, people just stopped using it.

dicksewerrat: If you were truly installing pipe in the 1880's, one would have to agree that was "along time ago", not "that long ago".
