What Is the Lifespan of Sewer Pipes?

The lifespan of sewer pipes can vary depending on several factors, such as the material used, the environment and manner in which they are installed, and the level of maintenance and care they receive, among other things. Need to check whether your sewer pipes are up for a replacement or likely in need of trenchless pipe repair in Kailua-Kona, HI? Here are the average lifespans of different sewer pipe materials.

Cast Iron

Cast iron pipes have been broadly utilized for sewer systems in the past. They are prominent for their durability and long lifespan, ranging from 50 to 100 years. Nevertheless, the lifespan can be affected by factors such as soil conditions, corrosion, and chemicals in the wastewater.

Clay

Clay pipes have been used for sewer systems for centuries due to their resistance to chemicals and durability. The average lifespan of clay pipes can range from 50 to 60 years. However, they are susceptible to cracking or breaking if subjected to excessive pressure or ground movement. Luckily, trenchless pipe repair can be utilized when clay pipes become damaged.

PVC (Polyvinyl Chloride)

PVC pipes have become increasingly popular in modern sewer systems due to their affordability, lightweight nature, and resistance to corrosion. PVC trenchless pipe replacement can be done after 50 to 70 years, depending on the quality of the material and the installation.

It is important to note that these lifespans are estimates and can be influenced by various factors. Environmental conditions, such as soil acidity, temperature fluctuations, and corrosive substances, can impact the deterioration rate of sewer pipes.
