Question: How Long Does a Sewer Line Last?
Top Answer (25% of 8 votes): 40-60 years.

Answer: 60-80 years
Explanation: Depending on the material used during installation. Cast iron corrodes and breaks down 45 to 60 years is typical prior to needing replacement. Terra cotta (clay) can last longer if it is installed on a hard bottom ditch with no settlement and no big trees nearby. Same for concrete. Proximity to large trees is always the worst scenario. A properly installed PVC sewer service line is good for a 100 years.
