Sewer line replacement options for Lebanon County yards and driveways

Hearing that your underground sewer line has collapsed or broken beyond repair is news no homeowner in South Lebanon Township or Lebanon County, PA wants to receive. In the past, replacing a sewer lateral meant watching a backhoe tear a deep, destructive trench through your manicured lawn, front walkway, and paved driveway.

Fortunately, modern plumbing technology offers homeowners multiple paths forward. Understanding the differences between traditional open-cut excavation and modern trenchless pipe bursting allows you to make the best financial and structural decision for your property.

Option 1: Trenchless Pipe Bursting

• How It Works: Instead of digging up the entire line, we excavate only two small access pits—one where the sewer leaves your home, and one at the property boundary or street main connection. A heavy steel cable is fed through the old pipe and attached to a conical hardened-steel bursting head.
• The Bursting Action: Powered by a high-tonnage hydraulic pulling machine, the conical head is pulled through the old damaged clay or cast iron pipe. As it advances, it shatters the old pipe outward into the surrounding soil while simultaneously pulling a continuous, heavy-duty High-Density Polyethylene (HDPE) pipe into place behind it.
• Key Benefits: No trenches through beautiful landscaping, paved driveways, or concrete porches. The resulting HDPE line is completely continuous, eliminating all joints where tree roots could ever enter in the future.

Option 2: Traditional Open-Trench Excavation

• Pipe Bellies & Loss of Grade: If your existing sewer lateral has settled into a severe belly (a sagging dip where water pools), pipe bursting will follow the same dip. Open-trench excavation allows us to dig down, re-establish a true 1/4-inch per foot slope, and bed the new Schedule 40 PVC pipe in crushed stone.
• Completely Collapsed Lines: If the old pipe has suffered a total collapse where a cable cannot be fed through, excavation is required to remove the blockage.
• Utility Conflicts: If other utilities (gas lines, electric conduits) run directly adjacent to the sewer line, careful open excavation avoids accidental utility damage.

Point Repairs: Targeted Sectional Fixes

If our video camera inspection reveals that 90% of your sewer lateral is sound and the failure is isolated to a single crushed joint near the foundation or under the sidewalk, a full replacement may be unnecessary. We can perform a targeted 'point repair,' excavating only a 6-foot window to replace the broken joint with heavy-gauge PVC and shielded transition couplings.

Honest Local Assessments

We always inspect the entire lateral with fiber-optic cameras before recommending any replacement strategy. Call our South Lebanon team at (207) 419-2600 to explore your options and receive upfront, transparent pricing.
