The beautifully constructed Union Station located in Oklahoma City, is a historical building worth preserving as it is listed on the National Register of Historic Places. Due to its historical significance the 55,000 square foot building is set to become a museum. Unfortunately the building was moving causing cracks and damages. The safety of this building was in jeopardy and that worried the building owners.

On a mission to preserve this building, Oklahoma City, hired engineers to inspect the cause of the damages occurring. Upon inspection it was discovered the pipe was leaking. The pipe leak was so intense it caused the soil in the ground to separate. The erosion caused Union Station to be slightly displaced. The detrimental pipeline was compromising the structural integrity of the building. The engineers also noticed the fragile state of the building and advised it not be vigorous renovations with a lot of vibrations. The sewer pipe system consisted of pipes 8” in diameter and more than half of that consisted of blockages making cleaning them a very difficult challenge.

After a lot of deliberations, Union Station concluded the best solution for their frail sewer line was trenchless pipe lining. After consulting many professional pipelining companies they heard virtually the same answer: Rehabilitating such damaged pipelines is IMPOSSIBLE.

In a final attempt to save the pipe, Union Station consulted with A Nu Flow Licensee – Hi-Tech Plumbing and Leak Detect (HTPLD). Confident in their abilities and Nu Flow’s patented pipe lining process, HTPLD went ahead and assured Union Station they were up for the challenge.

The first issue they tackled was the corrosion build up which took up most of the pipe. Using Nu Flow’s cutting tool the broke apart the minerals and then pushed them out. The pipes were then back to their original diameter.

HTPLD then installed the epoxy pipe lining into the brittle pipes. The patented process , where an epoxy saturated liner is pulled into a damaged pipe system. The epoxy pipe liner was put into the sewer lines, which then cured. This creates a pipe-within a-pipe liner in the host pipes. While the liner is restoring the pipe, it also is increasing the lifeline of it as well.

Many trenchless pipe lining companies dubbed this project to be impossible, however Nu Flow Technologies Licensee, Hi-Tech Plumbing and Leak Detection proved them wrong! They also saved a historically rich building from any damages.
