Sewer Contracting


We are a licensed and bonded sewer contractor in the city of Los Angeles, though it may be easy to mistake companies like ours as a plumber.

Our license and years of experience enable us to provide services that require work in the streets, under sidewalks, or in the public right of way. As with any project, when looking for a sewer contractor it’s important to choose someone familiar with your type of work.

L.M. Olson, Inc. works for commercial and industrial contractors, as well as residential customers.

New Lateral Connections

This service is provided when the contractor needs a new lateral from the sewer mainline to the property line. As this service is a key part of many projects our team is highly experienced in lateral connections.

Septic Tank Abandonment

We offer septic tank abandonment services.

Lateral Replacement

We offer a traditional-style lateral replacement, which consists of an excavation cut from one end of the lateral to the other.

Trenchless Line Replacement

Advances in technology have changed the processes for replacements and enable us to provide more durable solutions. This style of replacement is less invasive, making it easier to preserve the landscape and other surrounding elements of the property.

Spot & Line Repair

When a video inspection reveals an easily localized blockage or collapse, we can isolate the compromised section and repair it with minimal invasiveness. Call us for information about spot repair options.

Grease Interceptors

New installation or removal of existing grease interceptors.
