Why are sewer lines made out of clay?
Clogged drains quickly back up into buildings. Most older sewer lines are made from clay, and even most newly built structures with PVC drain lines eventually discharge into a city waste system comprised of clay pipes. Any product that would dissolve dirt and clay lodged in a drain pipe would also attack the system itself at some juncture.
How long does it take to make clay sewer pipes?
Modern vitrified clay sewer pipes are air dried for 24 hours and then fired in a kiln for 50 hours, creating a ceramic-like end product. This material, also referred to as terra cotta, is stronger and fits together more tightly than older clay plumbing.

What’s the difference between terra cotta and clay sewer pipes?
This material, also referred to as terra cotta, is stronger and fits together more tightly than older clay plumbing. It’s still routinely used in public sewer systems today. Modern installations include encasing the clay pipes in concrete to protect against root intrusion and damage from ground shifting.

What are the pros and cons of clay sewer pipes?
Cons of Clay Sewer Pipes Hard to work with: PVC is much easier to handle, with its light weight and smooth surfaces that connect easily and securely. Difficult to transport: Clay is incredibly heavy, which is why many cities in the 19th and 20th centuries had their own pipe manufacturing plants.

Which is better for a sewer line clay or ABS?
In most new sewer line installations, you may find yourself being steered in the direction of PVC or ABS plastic pipe over clay and cast-iron. While the plastic pipe is undoubtedly easier to work with, clay and iron have strong points, such as longer lifespans and strength (for the iron). Plastic: PVC and ABS
