Sewer Pipes

For generations, different types of sewer pipes have been used. As a result, knowing the different types of obsolete and new sewer pipes can aid in proper maintenance or the design and installation of an efficient sewer pipe system.

What Are Sewer Pipes?

Sewer pipes are used to dispose of waste. Sewer pipes are made of various materials and come in a variety of sizes.

Sewer pipes’ main job is to transport wastewater or sewage from residential or commercial structures to the drainage system so it can be treated or removed. Sewer pipes can become damaged or decay over time, necessitating repairs or replacement.

The sewer pipes are installed a few feet beneath the surface, providing the home and business owners with a good amount of clear space. Various types of sewer pipes are used depending on the weather in the area, and they are also repaired, replaced, or upgraded depending on the time.

This article discusses the various types of sewer pipes, including cast iron,clay, copper, PVC, acrylonitrile butadiene styrene (ABS),  and Orangeburg.


Types of Sewer Pipes| Cast Iron Sewer Pipe

cast Iron Sewer Pipe

This type of sewer pipe is typically used in older residences. Cast iron sewer pipes are great because, in comparison to other sewer pipes, they have incredible strength. It is stated that a linear foot of 4 inch-diameter cast-iron pipe can sustain 2 tons of pressure. Other pipes, such as ABS, PVC, and clay pipes, have the potential to break. Despite its enormous strength, it has some drawbacks, such as the fact that it is difficult to operate due to its weight and difficult to cut the pipe to the appropriate length.

Concrete Pipes

Concrete Pipes

Concrete has been used as a piping material as well as an encasement for clay piping. Concrete sewer pipes are extremely durable, with an average life span of about 30 years. Concrete is regarded as one of the sewer pipe materials of the new generation, along with plastics. While concrete sewer pipes are not immune to damage or aging, which can require repairs or replacement, this type of sewer piping is currently popular due to its affordability, strength, and longevity.

Types of Sewer Pipes| Clay Sewer Pipes

Clay Sewer Pipes

The most common type of sewer pipe is clay sewer pipe. These are capable of transporting the majority of waste and are constructed from a clay and shale mixture. They are also inert, which means they will not catch fire. Despite being rust-proof, reinforced concrete pipes are more durable than clay pipes. Although they are the least expensive option, these pipes are prone to cracking when placed under extreme pressure.
Due to more advanced and effective materials, these are now rarely used and difficult to find on the market.

Types of Sewer Pipes| Copper Pipes

Copper Pipes

These sewer pipes are thought to be more expensive than other types of pipes. However, they are incredibly durable and have the highest level of heat resistance. Copper pipes can be utilized in situations when the walls of the pipe may expand, as well as when the sewer pipe is covered in concrete.

Types of Sewer Pipes| Galvanized Pipes

Galvanized Pipes

Galvanized pipes are designed to endure longer and are commonly used in household drainage systems. Galvanized pipes are strengthened by being dipped in molten zinc. Actually, they are designed to withstand rust. However, despite being slightly more expensive due to their complex manufacturing process, galvanized pipes can be used practically everywhere in your house.

Orangeburg Sewer Pipe

Orangeburg Sewer Pipe

Orangeburg pipe is a bituminized pipe made of layers of wood pulp fibers crushed and bonded by a water-resistant adhesive coated with liquefied coal tar pitch. The sewer pipe has the benefit of being water-resistant since it has a water-resistant adhesive added to it. Currently, in the plumbing system, plumbers are accustomed to preferring this type of pipe since it is lightweight and simple to cut to the required size with a standard wood saw. This type of pipe decreases installation stress when first laid on a sand bed for proper fiber conduit pipe installation. Because this type of pipe has a lifespan of more than 50 years, it is no longer visible in the plumbing system.

Types of Sewer Pipes| PVC and ABS Sewer Pipe

PVC & ABS Sewer Pipe

PVC and ABS sewer pipe are two types of plastic pipe; PVC is white plastic pipe and ABS is black plastic pipe. Both the black and white plastic pipes for solid waste have a smooth interior part for carrying. At the same time, it has a smooth exterior that helps prevent tree root anchorage. The PVC and ABS plastic pipe has a diameter of 4 inches and is very easy to use and readily available near the construction site. Nowadays, these types of pipes are the most common and affordable, as well as the easiest to cut and lightweight. Another advantage of this kind of plastic pipe is that it can be used with cast-iron and clay pipes.

Most Common Types of Sewer Problems


Pipe corrosion

The sewer line’s pipes react to the wastewater as it passes through them. Metal sewer lines are commonly used in most homes. Excessive corrosion speeds up line wear and tear and raises the risk of leaks into your home. To find corrosion, conduct a camera inspection.



This occurs when you flush items that cannot drain correctly down your drain. If you flush diapers, wipes, and tampons down the toilet, you risk clogging it. Water backup, gurgling pipe noises, and slowed drains are the most common signs of a blockage.


Tree root intrusion

Tree roots may come into contact with your sewer line when they extend out in search of moisture. If the pipes have cracks, the roots may, over time, cause them to collapse or cause sewer blockages. Therefore, to prevent future sewer issues, be aware of where your plumbing systems are located when planting trees.


Pipe shifting and breakage

Your sewer pipes may also burst due to aging and pipe displacement, in addition to tree roots. Your sewage line may start to alter shape and obstruct appropriate wastewater drainage when your foundation changes as a result of too much weight or when excessive rainwater seeps underground.


The house has a sewage odor

This seemingly insignificant issue could have a huge impact on your indoor air quality and comfort. Whenever your drain caps are missing or not properly installed, your home may begin to smell like the sewer system. Practice checking your P-traps or drain caps.
