Sewer Line Replacement: Traditional vs. Modern Methods

A damaged sewer line is one of the most significant plumbing challenges a homeowner can face. For decades, the only solution involved massive excavation that destroyed landscapes, driveways, and sometimes even parts of the home itself. Today, homeowners have choices. At Judd's Plumbing, we believe in educating our customers about both traditional and modern approaches so you can make the best decision for your property and budget.

The Traditional Approach: Excavation Sewer Replacement

How It Works:

Traditional sewer replacement is exactly what it sounds like—heavy machinery digs a trench along the entire length of the damaged pipe, exposing it completely. The old pipe is removed, new pipe is laid in the trench, and the excavation is backfilled.

The Process:

Site Marking: Utility lines are located and marked
Major Excavation: Large equipment digs a deep trench across your property
Pipe Replacement: Old pipe is removed and new pipe installed
Backfilling: The trench is filled with soil
Restoration: Landscaping, hardscaping, and surfaces are repaired or replaced

When Traditional Might Be Necessary:

Severely collapsed pipes that cannot be pulled through
Major pipe misalignment that prevents trenchless methods
Extensive root damage throughout the pipe system
Situations where multiple utility lines complicate trenchless access

Advantages:

Complete visual inspection of the entire pipe run
Can address other issues found during excavation
May be less expensive for very short replacement runs

Disadvantages:

Massive property destruction requiring extensive restoration
Longer project timeline (often weeks including restoration)
Higher overall cost when restoration is factored in
Significant disruption to daily life and property use

Modern Trenchless Sewer Replacement Methods

Method 1: Pipe Bursting

How It Works:

A conical bursting head is pulled through the old pipe, simultaneously fracturing it outward while pulling a new HDPE (high-density polyethylene) pipe into place behind it.

The Process:

Two small access pits are dug (at start and end points)
Bursting equipment is set up
Old pipe is fractured as new pipe is pulled through
Connections are made at both ends

Best For:

Replacing severely damaged but not collapsed pipes
Upsizing to a larger diameter pipe
Situations where minimal disruption is critical

Method 2: Cured-In-Place Pipe (CIPP) Lining

How It Works:

A flexible epoxy-saturated liner is inserted through an access point and inflated against the host pipe's interior walls. The epoxy cures, creating a "pipe within a pipe."

The Process:

Small access point is created
Pipe is cleaned and prepared via hydro-jetting
Epoxy-saturated liner is inserted and inflated
Heat or UV light cures the liner solid
Ends are trimmed and connections restored

Best For:

Pipes with cracks, holes, or root intrusion
Preventing future corrosion and root problems
Situations where maintaining existing pipe diameter is acceptable

Comparing the Two Approaches

Property Impact:

Traditional: Extensive damage to landscaping, hardscapes, and structures
Trenchless: Minimal disruption, often only small access points required

Project Timeline:

Traditional: 3-7 days for excavation plus weeks for restoration
Trenchless: Typically 1-2 days from start to completion

Cost Considerations:

Traditional: Lower upfront plumbing costs but significantly higher restoration expenses
Trenchless: Higher plumbing costs but minimal to no restoration costs

Long-Term Results:

Traditional: New pipe with expected 50+ year lifespan
Trenchless: New pipe or liner with 50+ year lifespan, often more resistant to roots and corrosion

How to Determine Which Method is Right For You

Start with a Camera Inspection:

Before any decisions are made, our technicians perform a comprehensive camera inspection to assess:

Extent and type of damage
Pipe material and condition
Pipe location and depth
Access points available

Consider These Factors:

Your landscaping: Are you willing to have it destroyed and restored?
Your timeline: How quickly do you need the problem resolved?
Your budget: What can you afford for both plumbing and restoration?
Future plans: Are you planning to sell or make other property improvements?
