The Pottawatamie County Jail is near 100 years old. The drain piping was damaged inside an old concrete wall in the basement. This drain line was cracked and leaking. Hi-Tech Plumbing & Leak Detect, Inc. was able to clean the line, pull a new pipe liner inside the existing pipe, without compromising the integrity of the basement walls in the historically protected building. Utilizing the NU FLOW trenchless technology, cured-in-place (CIPP) repair method, Hi-Tech Plumbing & Leak Detect, Inc. was able to successfully repair the pipe, without a single person in the building being relocated or pulled from their day-to-day operations.
