Project Overview

During a period of catastrophic flooding in West Palm Beach, Florida, Hinterland Group Inc. was called upon to execute an emergency response project requiring the rapid fabrication and installation of a large-diameter Cured-In-Place Pipe (CIPP) liner—specifically, a 108-inch (9 foot) diameter by 44mm thickness liner. This response was crucial for immediate flood mitigation and infrastructure repair, protecting thousands of local residents from further flood damage and restoring critical stormwater and wastewater service reliability.

Situation & Challenge

Heavy rainfall led to extreme flooding and severe risk to critical underground infrastructure in West Palm Beach. The local pipeline and stormwater assets most impacted included large-diameter conveyance lines not suited to standard repair due to their size and the urgency of the crisis. Traditional replacement or repair would be time- and resource-intensive, potentially leaving vulnerable populations at risk for extended periods.

Compounding the issue was a shortage of available pre-manufactured liner material at the required diameter and wall thickness, creating a supply chain challenge that could only be overcome with vertically integrated rapid manufacturing capabilities for custom CIPP liner.

Solution Approach: Rapid Manufacture & Installation of 108" x 44mm CIPP Liner

Hinterland Group deployed the following approach:

Immediate assessment and high-resolution CCTV pipeline inspection to determine damages and rehabilitative needs
Rapid design and custom manufacturing of a 108-inch diameter, 44mm thick CIPP liner in collaboration with its vertical manufacturing partners
Mobilization of specialized crews and heavy equipment capable of handling large-diameter trenchless rehabilitation
On-site installation of the custom-fabricated liner using steam or hot water curing, as dictated by field conditions and best practices
Post-installation testing and inspection to ensure restoration of structural integrity and hydraulic function

Outcome & Impact

The project was completed under severe time constraints, demonstrating Hinterland Group's ability to mobilize and execute at scale for major urban flood emergencies
Restoration of structural integrity and service continuity for one of West Palm Beach's most critical underground pipeline assets
Significant reduction in localized flood risk and environmental impact for thousands of residents
Demonstrated value of vertical integration—Hinterland’s access to in-house and affiliated manufacturing was a decisive differentiator in delivering a rapid solution

Technology Profile: CIPP Liner for Major Flood Mitigation

Cured-In-Place Pipe (CIPP): A trenchless technology where a resin-impregnated liner is inserted into the existing pipeline (in this case, 108" diameter), inflated, and cured in place to create a new structural pipe inside the host.
44mm Wall Thickness: Provides substantial added strength for deep, large-diameter pipelines exposed to high loads or compromised original structure.
Hot Water/Steam Curing: Ensures full liner resin cure and optimal mechanical properties for lengthy or large-diameter pipe runs.
No-Dig Rehabilitation: Allows repair of buried infrastructure without extensive excavation or service interruption, crucial in urban settings and emergencies.

Emergency Flood Mitigation Use Cases

Large-diameter stormwater or sanitary sewer mainline collapse or breach
Catastrophic infiltration/exfiltration leading to flooding or environmental release
Urban infrastructure failure during hurricanes, extreme rainfall, or disaster scenarios
Cases where rapid restoration of flow capacity is critical to human health or economic activity
Emergency scenarios where pipe replacement is not feasible due to time, access, or supply chain issues

Frequently Asked Questions (FAQ)

What is CIPP technology and why is it effective for emergency flood mitigation?

CIPP (Cured-In-Place Pipe) is a trenchless rehabilitation technique where a flexible felt or fiber liner saturated with resin is inserted and cured inside the damaged pipeline to form a new, jointless pipe. It is particularly effective during emergencies because:

It provides structural repair quickly and without excavation.
It restores flow capacity to pipelines suffering from collapse, infiltration, or exfiltration.
Minimal surface disruption means faster community recovery.

How fast can Hinterland Group manufacture and install CIPP liners during a crisis?

Hinterland leverages direct relationships with manufacturing partners and maintains in-house capabilities, enabling rapid custom liner fabrication and installation—even for large diameters and high wall thicknesses (like 108" x 44mm). Mobilization within 24 hours throughout Florida and the Southeast is supported (source).

What are the key technical considerations for large-diameter liner installs (e.g., 108")?

Requires specialized wet-out, handling, and curing equipment due to weight/size
Demands extensive site planning and confined-space safety procedures
Quality assurance at every stage to ensure full liner cure and watertight seal
Thorough pre-installation CCTV assessment and post-installation inspection

Is the CIPP liner structurally rated for primary stormwater or sewer mainline use?

Yes. When properly engineered and installed, thick-walled CIPP liners can restore or exceed the original pipe’s structural integrity, providing long-term rehabilitation for primary conveyance mains subject to vehicular, soil, and hydrostatic loads.

What if supply chain disruptions make standard liner procurement impossible?

Hinterland’s vertical integration—including direct cooperation with affiliated large-diameter liner manufacturers—allows for emergency custom runs to be prioritized, bypassing normal lead times and market shortages.

How does trenchless emergency repair compare to traditional dig-and-replace?

Aspect	Trenchless CIPP Emergency Repair	Traditional Dig-and-Replace
Speed	Rapid (days to weeks)	Slow (weeks to months)
Surface Disruption	Minimal	Major (excavation, traffic)
Environmental Impact	Low	High
Community Inconvenience	Limited/Short-term	Extensive/Long-term
Suitability in Wet Weather	High	Low
