Two NuFlow Certified Contractors joined forces to complete a 4,300-foot in-building pipe rehabilitation at a Colorado ski resort – compressing a 180-day schedule into just 90 days using NuDrain pull-in-place CIPP, NuCure UV curing, and brush coating technologies.

Project Overview
The HOA of a condominium building at a popular Colorado ski resort faced an escalating plumbing crisis. Built in the early 1980s, the property’s cast-iron infrastructure – spanning both vertical stacks and horizontal sewer lines, had reached the end of its service life. Over four decades of wear, corrosion, and buildup had led to chronic blockages, backups, and leaks that threatened the comfort of the guests and value of the property.
The HOA’s building consultant reached out to NuFlow Technologies for a consultation. After evaluating the extensive scope – over 4,300 feet of failing cast-iron lines – NuFlow connected the project with two trusted Certified Contractors: King Rooter & Plumbing and Anytime Plumbing. Recognizing the project’s complexity and compressed schedule, the contractors made a strategic decision to join forces – sharing resources, expertise, and profits to ensure success.
The Challenge
The project was originally designed as a 180-day rehabilitation, but the HOA requested completion before the July 4th holiday weekend—cutting the timeline in half. The new 90-day deadline introduced intense pressure, compounded by several technical challenges:
- Limited access required opening walls and adding new cleanouts for staging.
- Heavy corrosion and scale buildup demanded extensive jetting and mechanical descaling.
- The building’s separate vent and sewer stacks required additional access points and extended lining efforts, complicating sequencing and logistics.
- Several three-way wyes and damaged fittings were found during inspection, requiring traditional replacement in tight, hard-to-reach areas.
Execution and Technologies
A crew of 10 trenchless technicians and plumbers worked onsite daily, coordinated by both company owners, who alternated visits to maintain oversight and project continuity.
The team used NuFlow’s Field Quality Assurance system to track progress, share video and photo documentation, and communicate directly with the HOA. This ensured full transparency and streamlined reporting throughout the accelerated schedule.
Hybrid Trenchless Strategy
To address a range of pipe conditions and access points, the contractors employed a combination of complementary technologies:
- NuCure Cold Cure UV (UV-cured pull-in-place CIPP) accounted for approximately 60% of the lined pipe, offering rapid, controlled curing where temperature or access limited ambient methods. Crews would prep and drop multiple NuDrain liners at the start of each day, then switch to UV curing while those liners set.
- NuDrain CIPP (ambient-cure pull-in-place) was used strategically in sections where traditional curing was preferred or access allowed for longer setup times.
- A combination of gapping and reinstatement techniques were performed on branch connections, with traditional replacement used for select wye fittings that were too deteriorated for lining.
- Picote Xpress Brush Coating System was used at connection joints to provide complete coverage and sealing after reinstatement to apply a protective epoxy barrier on pipe surfaces that remained structurally sound but required corrosion protection and improved flow.
This targeted, hybrid approach maximized production efficiency and system longevity while minimizing building disruption.
Results and Takeaways
By June 30, crews completed cleaning, lining, reinstatement, and demobilization—meeting the HOA’s July 4th deadline. In total, 4,300 feet of pipe ranging from 2” to 8” were successfully rehabilitated using trenchless methods, with no excavation or downtime for the resort.
“This was one of those projects where teamwork made all the difference,” said Jeff Lane, owner of King Rooter & Plumbing. “We took a 180-day project and delivered it in 90. It was stressful at times, but thanks to great coordination between the two companies and the support of NuFlow, we finished on time and with pride.”
Post-project verification revealed only one minor leak, traced to a deteriorated section outside the lined area, which was quickly repaired. Two technicians remained onsite after completion to monitor system performance and address any residual issues.
Technology Spotlight: NuFlow’s Multi-System Advantage
By integrating NuDrain CIPP, NuCure Cold Cure UV, and Picote Xpress brush coating, the contractors were able to deliver both structural renewal and preventive protection within the same system.
This hybrid rehabilitation model is ideal for multi-story properties with mixed pipe conditions—providing flexibility, faster cure times, and extended service life without excavation.
This project exemplifies how modern small-diameter trenchless rehabilitation can meet complex challenges under compressed timelines. Through detailed coordination, innovative technologies, and a true spirit of collaboration, King Rooter & Plumbing and Anytime Plumbing delivered a durable, non-invasive renewal solution—ensuring the ski resort was ready for guests right on schedule.
