When Do You Need a New Sewer Line?
There are several situations where a new sewer line installation may be necessary:
New Construction
If you're building a new home or an addition that requires plumbing, a sewer line must be installed to connect the property to the municipal sewer system. Professional installation ensures proper slope, flow, and compliance with local building codes, setting the foundation for a reliable plumbing system from day one.
Severely Damaged Pipes
Pipes that are cracked, collapsed, or crushed, often due to soil shifting, root intrusion, or age, may be beyond repair. In these cases, a full sewer line replacement is the most effective and long-lasting solution. Damaged pipes can lead to frequent backups, foul odors, and potential contamination, making timely replacement essential.
Upgrading Old Infrastructure
Older homes often have sewer lines made of outdated materials like clay, cast iron, or Orangeburg (compressed wood fiber), which degrade over time. These materials are prone to corrosion, leaks, and root intrusion. Replacing them with modern, durable piping like PVC ensures greater reliability and long-term performance.
Poor Drainage or Frequent Backups
If you’re constantly dealing with slow drains, recurring clogs, or sewage backups, the issue may be deeper than a simple blockage. These signs often indicate a failing sewer line that needs replacement. A professional inspection can determine if installing a new line is the best long-term fix.
Major Home Renovations
Planning a significant remodel, such as adding a bathroom or expanding your kitchen? Your current sewer line may not have the capacity to handle the increased flow. A new sewer line installation ensures your updated plumbing system can perform efficiently and comply with local code requirements.
Our Installation Process
At Ongaro & Sons, we begin every project with a detailed site evaluation and sewer line inspection. We’ll walk you through every step of the process, from selecting the right materials to securing permits and ensuring code compliance. Our team uses proven installation methods to minimize disruption to your property while ensuring long-lasting results.
Depending on your property and needs, we may recommend:
- Traditional Excavation for full line replacement
- Trenchless Installation Methods, such as pipe bursting or pipe lining, for a faster and less invasive solution
To make your project even more manageable, we offer flexible financing options (on approved credit), helping you complete the work you need without straining your budget.

Why Ongaro & Sons for Sewer Line Installation
A new lateral is set once. Grade and bedding decide how it performs for the next fifty years.
Schedule Service →Grade set correctly, because it cannot be adjusted later
Too flat and solids settle. Too steep and liquid outruns them. Both produce blockages that look like a usage problem.
C-42 sanitation system classification
The classification the work requires in Santa Rosa, held directly rather than borrowed.
Bedding and backfill done properly
Most premature failures on new laterals are bedding failures. Compaction and material matter as much as the pipe.
Connection and permitting coordinated
Connecting to the main means coordinating with the jurisdiction as well as the county. We manage the sequence.
North Bay since 1932
A new lateral is inspected before it is covered, and that record follows the property. Ongaro & Sons has worked in these counties since 1932.
