Case Study
Emergency Trenchless Pipeline Repair in Nashville's Gulch District
Project Overview
Client: Rental Property Owner, The Gulch, Nashville
Location: The Gulch District, Nashville, TN
Service: Trenchless Pipeline Relining (CIPP)
Timeline: 3 Hours (Same Day Completion)
Challenge: Offset Joint Between PVC and Cast Iron Under Marble Patio
Result: Zero Excavation, Minimal Disruption, Happy Tenants
The Challenge: Sewer Emergency in Historic Gulch Property
When a rental property owner in Nashville's prestigious Gulch district contacted Prodigy Sewer & Drain, they were facing a plumbing nightmare. The property's sewer system had failed, leaving tenants without working plumbing and threatening the beautiful marble patio that was a centerpiece of the property.
Initial Problems Discovered
The property was experiencing multiple critical issues:
- Complete sewer backup – Tenants couldn’t flush toilets or use drains
- Previous partial repair – Another plumber had fixed one broken pipe but missed the root cause
- Hidden structural issue – An offset joint between PVC and cast iron piping was causing the failure
- Difficult access point – The problem area was directly beneath an expensive marble patio
Property Constraints
This wasn’t a typical repair job. The Gulch property presented unique challenges:
- High-value marble patio that couldn’t be damaged or removed
- Active tenants needing immediate resolution
- Historic district with strict renovation guidelines
- No access for traditional excavation equipment
- Tight timeline to restore property functionality
Tenant Impact
With the sewer system down, tenants were unable to:
- Use any plumbing fixtures
- Flush toilets
- Run water through drains
- Maintain basic hygiene and daily routines
The property owner needed an immediate solution that wouldn’t require weeks of excavation work or damage to the expensive hardscaping.
Our Solution: Trenchless CIPP Relining
After assessing the situation, our team at Prodigy Sewer & Drain determined that trenchless cured-in-place pipe (CIPP) relining was the perfect solution. This advanced technology would allow us to repair the damaged pipeline without excavating the marble patio.
Inspection & Diagnosis
We began with a comprehensive CCTV camera inspection to pinpoint the exact location and nature of the problem. Our high-definition cameras revealed:
- The precise location of the offset joint beneath the marble patio
- The connection point between PVC and cast iron piping
- Additional stress points in the line
- The overall condition of the sewer system
The Prodigy Approach
Our strategy focused on three key principles:
- Minimal Disruption: Complete the repair without disturbing the marble patio or landscaping
- Maximum Speed: Restore full functionality within hours, not days or weeks
- Long-Term Reliability: Install a solution that would last 50+ years
Technology Used
We deployed our advanced trenchless technology suite:
- High-Definition CCTV Cameras: For precise diagnosis and post-repair verification
- CIPP Relining Equipment: To create a seamless new pipe within the existing damaged line
- Specialized Curing Systems: To ensure proper installation and immediate strength
- Professional-Grade Testing Tools: To verify complete restoration of flow and function
Step-by-Step Repair Process
Step 1: Advanced Camera Inspection
Time: 30 minutes
Our certified technicians inserted a high-definition camera through the existing access point to map the entire sewer line. We identified the offset joint where the PVC section met the cast iron pipe, located precisely beneath the marble patio. The camera footage confirmed that traditional excavation would require removing several square feet of expensive marble.
Step 2: Identifying the Offset Joint Issue
Time: 15 minutes
The camera inspection revealed that while another plumber had recently repaired a broken pipe, they had missed the critical offset joint. This joint misalignment was causing sewage to back up and preventing proper drainage. The location under the marble patio made traditional repair methods impractical and expensive.
Step 3: Trenchless Relining Installation
Time: 90 minutes
Using our trenchless CIPP technology, we:
- Cleaned the existing pipe thoroughly using hydro jetting
- Inserted a resin-saturated liner through the access point
- Positioned the liner precisely to cover the offset joint and surrounding pipe
- Inflated the liner to conform to the pipe walls
- Cured the resin using our specialized system, creating a new, seamless pipe within the old one
The new pipe bridged the problematic joint between PVC and cast iron, eliminating the offset and creating a smooth, continuous flow path.
Step 4: Quality Testing & Verification
Time: 45 minutes
After the liner cured, we:
- Conducted another camera inspection to verify the repair quality
- Tested water flow and drainage
- Checked for any potential leaks
- Ran multiple flush tests to ensure full functionality
- Provided the property owner with before-and-after camera footage
Results: 3-Hour Turnaround with Zero Excavation
Just three hours after we arrived on site, the tenants were back to using their plumbing normally. The marble patio remained completely untouched, and the property owner avoided weeks of disruption and tens of thousands in excavation and restoration costs.
