Introduction:
Sewer laterals are essential pipes that connect a home's plumbing system to the public sewer main. They play a crucial role in transporting wastewater away from homes for proper treatment and disposal. Maintaining sewer laterals regularly is vital to prevent issues like clogs, which can lead to sewage backups, property damage, and potential health hazards.
Several things can cause clogs in sewer laterals. Some of the most common causes include:
- Flushing non-flushable items down the toilet. This includes items such as wipes, paper towels, diapers, and feminine hygiene products. These items can clog the sewer lateral and cause backups.
- Grease and oil buildup. Over time, grease and oil can build up in the sewer lateral and harden, which can eventually clog the pipe.
- Tree roots. Tree roots can grow into sewer laterals and cause damage. This can lead to leaks and clogs.
- Foreign objects. If foreign objects, such as toys or jewelry, are flushed down the toilet, they can get stuck in the sewer lateral and cause a clog.

Understanding Sewer Laterals
What is a Sewer Lateral?
Sewer laterals, also referred to as house sewers or drain waste vent (DWV) pipes, are essential components of a home's plumbing system. These pipes, typically buried underground, play a critical role in transporting wastewater from a residence to the public sewer main for proper treatment and disposal. Sewer laterals are commonly made of clay, cast iron, or PVC and typically measure 4 to 6 inches in diameter.
A sewer lateral is a pipe that connects a home's plumbing system to the public sewer main. It is typically made of clay, cast iron, or PVC and is buried underground. Sewer laterals are responsible for carrying wastewater from a home to the sewer main, where it is then treated and disposed of.
Sewer laterals are divided into two sections: the public section and the private section.
Public section:
The public section of the sewer lateral is the portion that runs from the sewer main to the property line. It is the responsibility of the municipality or sewer district to maintain the public section of the sewer lateral.
Private section:
The private section of the sewer lateral is the portion that runs from the property line to the house. It is the homeowner's responsibility to maintain the private section of the sewer lateral.
