5-Story Library Keeps Doors Open During Pipe Repairs

Downtown Library: Sanitary Drain System Rehabilitation

Situation: This 5-story, historic, public library, located in a heavily populated urban area, experienced sanitary sewer line failures. The diameters of these cast iron pipes are 2″ to 4″. Old age caused these pipes to leak. Out of fear, the library looked for long-term solutions to protect the books.

Solution: NuDrain was used to rehabilitate the leaking sanitary pipes. NuFlow’s non-invasive, patented technology was used to line the pipes in place, which prevented the need for destruction, library closure, or disruption to visitors. A protective pipe liner is installed in the pipe system which will prevent future leaks.

The staff of a historic, urban, public library can rest easy now that NuDrain has been applied to its aged and failing sanitary drain system. After a series of leaks and costly damage to some books, this 5-story library knew it needed an effective, long-term pipe rehabilitation solution to prevent further damage and disruption.

Project: Rehabilitate failing sanitary drain lines that are located in hard-to-access areas throughout a high-traffic, downtown library.

Customer and Site: A 5-story, historic, public library, located in a heavily populated, urban area. This particular downtown library is part of a library system that serves more than a million residents and contains millions of books.

System: Cast iron sanitary sewer lines that are 2″, 3″, and 4″ in diameter. These pipes are around 60 years old and are located in ceilings, walls, and under the concrete slab.

Problem: These sanitary pipes experienced leaks as a result of age, which prompted the customer to look for long-term solutions to prevent damage to the library’s books and other documents. Since the drainpipe system is located throughout the library’s walls, ceilings, and floors, an in-situ pipe system repair seemed ideal.

Circumvention: If the customer had chosen a traditional repipe repair, the ceilings, walls, and slab would have been ripped apart in order to replace the failing pipes. This would have caused severe disruption to the library’s normal operations and it would have been a time-consuming, inconvenient, and messy project.

Solution: NuDrain was used to rehabilitate the leaking sanitary lines and prevent failures from occurring in the future. NuFlow’s non-invasive, patented process was the best solution for the customer because the library remained open and the restrooms were available for use during the work.
