✈️ Whitehorse Airport Storm Line Rehabilitation

Client: Erik Nielsen Whitehorse International Airport
Pipe Size: 150mm (6″) Storm Drain
Location: Beneath Departure Lounge Water Feature
Service: Structural CIPP Lining (Trenchless)
Duration: 1 Day + Cure & QA

⚠️ Project Overview

A critical 6” storm line located under the departures lounge at Whitehorse International Airport was showing signs of structural failure. With a severe sag at 101 feet and a partial collapse at 116 feet due to rock intrusion, the pipe posed a serious risk to terminal operations and infrastructure.

Excavating through the finished flooring of a secure, active terminal was not feasible. Nu Flow BC was brought in to deliver a no-dig, trenchless solution.

🔧 Challenges

High-Traffic Area: Located directly under a secure, active passenger terminal
No External Access: Only one internal cleanout available
Pipe Damage: Sag and collapse with rock pushing from above
Operational Constraints: Needed to avoid demolition, disruption, and delays

⚙️ Our Solution

Nu Flow deployed a trenchless Cured-In-Place Pipe (CIPP) liner using internal access only.

Process Summary:

🪜 Accessed via interior cleanout
⚒️ Cleaned and descaled pipe using Picote Maxi-Miller with 10” Cyclone Chains
📊 CCTV verified damage and mapped liner requirements
✉️ Wet-out structural liner and inverted into place
⏳ Cured in place using ambient conditions
🔄 Post-lining CCTV confirmed 100% structural restoration

✅ Results

❌ Zero demolition of floors, walls, or finishes
⏱ Minimal downtime — terminal remained operational
✔️ Full structural restoration of a compromised storm line
📈 Extended system life with seamless, corrosion-resistant liner

🖼️ Site Highlights

Left: Terminal exterior with restored historic aircraft
Center: Technician preparing liner in secure interior corridor
Right: Departures lounge above repaired pipe — no evidence of intervention

“No Dig. No Disruption. Just Results.”

✨ Why Nu Flow

When excavation isn’t an option, Nu Flow delivers. Our trenchless lining technologies restore even severely damaged pipes using existing access points — fast, clean, and with minimal impact.

Trenchless rehab is ideal for high-risk, high-finish environments where failure is not an option. Whitehorse Airport avoided a major facilities shutdown, preserved critical infrastructure, and gained long-term performance in just one working day.
