The lifespan of a sewer line depends on several factors, including the material it’s made from, the environment it’s in, and how well it’s maintained. For example, a sewer line made from cast iron can last 75 to 100 years, while one made from PVC can last 50 years or more. And while clay pipes may only last 30 to 40 years, they’re often found in areas with high water tables or poor drainage, which can shorten their lifespan.

As for the environment, sewer lines that are buried deep underground tend to last longer than those that are shallow. This is because they’re less likely to be damaged by tree roots or other objects. And finally, proper maintenance is crucial to prolonging the life of any sewer line.

This includes regular cleaning and inspection, as well as prompt repair of any leaks or cracks.


Most sewer lines are buried between four and six feet underground, although the depth can vary depending on a number of factors. The soil type, for example, can dictate how deep a sewer line must be buried. In addition, the size and type of pipe used for the sewer line can also affect its burial depth.

Finally, local building codes may require that sewer lines be buried at a certain depth in order to prevent them from being damaged by frost or other environmental factors.
