Broken Underground Sewage Pipe
Broken Underground Sewage Pipe
(OP)
At a wastewater treatment plant, a 70-year old 180ft long 12in dia. crock pipe, located nearly 40ft below ground and conveying wastewater from an underground tank (via a manhole) to a tunnel, was recently found to leak and need replacement. There are several utility lines in the top 10ft of soil at this facility. Any idea about the best way to design for this replacement would be appreciated.

There are several companies in the US that do this kind of work, not sure about other locations.

I just attended a seminar for pipe rehabilitation. The company is able to line the entire pipe. They can also fix individual holes with a grout patch. If you are in the midwest you can check out their website http://www.visu-sewer.com/. With the depth, and other obstructions this may be the cheapest fix.
