The beautifully constructed Union Station located in Oklahoma City, Oklahoma, is a historical building 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 plagued by cracks and other damage. 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 find the cause of the damages. Upon inspection it was discovered a 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 took note of the fragile state of the station and advised against vigorous renovations that would cause vibrations in the building. Blockages constricted the 8-inch-diameter sewer lines by at least 50 percent, so cleaning them a very difficult challenge.

After a lot of deliberations, Union Station concluded the best solution for the frail sewer line was trenchless pipe lining. After consulting many professional pipe lining 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 assured Union Station they were up for the challenge.

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

HTPLD then installed the epoxy pipe lining into the brittle pipes. The epoxy pipe liner was put into the sewer lines and left to cure. This creates a pipe-within-a-pipe in the host pipes. While the liner is restoring the pipe, it also is increasing the life span of it as well.

Though many trenchless pipe lining companies claimed this project was impossible, Nu Flow Technologies’ licensee, Hi-Tech Plumbing and Leak Detection proved them wrong. They also saved a historically rich building from any damages.

Hi-Tech Plumbing and Leak Detect was established in 2000 as a full-service plumbing company serving the greater Oklahoma City area. Built on the foundation of customer service, HTPLD uses the most sophisticated techniques and equipment available in the industry today. For information on becoming a Nu Flow licensee, visit
