Sewer Lateral

Sewer laterals are an important part of a building’s plumbing system, as they allow wastewater to be transported away from the building and into the public sewer system.

Proper maintenance and regular inspections of sewer laterals help prevent blockages and other issues that can lead to costly repairs.

Let’s move on to know more about sewer lateral.

What is a Sewer Lateral?

A sewer lateral is a pipe that connects a building’s plumbing system to the public sewer system.

It is typically located underground and runs from the building’s foundation to the public sewer main. Sewer laterals are responsible for transporting wastewater away from the building, and it’s important that they are functioning properly to prevent backups and other issues.

It can be made of a variety of materials, including clay, PVC, and cast iron.

What is a sewer lateral inspection?

Regular maintenance and inspections of sewer laterals can help prevent issues and ensure that your plumbing system is running smoothly.

Issues with sewer laterals can arise due to blockages caused by tree roots or debris, corrosion, shifting soil, or other factors. If there is an issue with the sewer lateral, it can cause backups, slow draining, and other plumbing problems.

If you suspect that there is an issue with your sewer lateral, it’s important to contact a professional plumber. They can perform an inspection using specialized equipment and determine the cause of the problem.

Sewer lateral replacement

Sewer lateral replacement is a process of completely removing and replacing an existing sewer lateral with a new one. This process may be necessary if the existing sewer lateral is damaged, corroded, or has other issues that cannot be repaired.

Common issues with sewer laterals include blockages caused by tree roots, buildup of grease and debris, and damage caused by corrosion or shifting soil.

In some cases, a sewer lateral may need to be repaired or replaced in order to prevent further damage and ensure that the plumbing system is functioning properly.

SEWDEF and how to prevent future sewer problems

Our SEWDEF service is an automatic defect detection system in sewerage networks based on artificial intelligence and artificial vision. Analyzes sewer network videos for defects such as sedimentary deposits, sewer blockages and many others.

To known more about the SEWDEF system:

These types of sewer inspections are the most cost-effective way to pinpoint the exact location of the problem. With this information, you can act quickly.

Remember that this system is respectful with the environment, since there is no excavation for the simple hypothesis that the problem is in a certain point.


If there are blockages or overflows in the sewer lateral, it is necessary to clean the pipes or use other methods to clear the blockage.

In general, regular maintenance and inspections help ensure that your sewer laterals are working properly and prevent costly and dangerous problems from arising.
