Your home’s sewer main plays a crucial role in maintaining the functionality of your plumbing system. But, like all plumbing components, they don’t last forever.
Understanding the lifespan of your sewer main and the factors that can affect its longevity is essential for ensuring the reliability of your plumbing system. Keep reading to learn about the lifespan of sewer mains, including the different substrates used over the years.
In Cincinnati, sewer mains have been constructed using various materials, each with advantages, disadvantages, and lifespan expectations.
Clay: Clay pipes were commonly used for sewer mains in the early to mid-20th century. While clay pipes are durable and resistant to chemical corrosion, they are susceptible to cracking, root intrusion, and shifting soil conditions. The lifespan of clay sewer mains typically ranges from 50 to 60 years.

Cast Iron: Cast iron became a popular choice for sewer mains in the mid-20th century due to its strength, durability, and resistance to corrosion. Cast iron pipes are less prone to cracking than clay pipes but can still deteriorate over time due to rust and scale buildup. The lifespan of cast iron sewer mains ranges from 75 to 100 years with proper maintenance.
PVC: PVC pipes emerged as a modern alternative to clay and cast-iron sewer mains in the latter half of the 20th century. PVC pipes are lightweight, durable, and corrosion-resistant, making them an attractive option for residential plumbing systems. The lifespan of PVC sewer mains is estimated to be 100 years or more under normal operating conditions.
