Pipe Reaming Botswana

We have gone international!!

Many attempts by means of conventional pipe cracking were tried and failed by the contractor onsite, the process was significantly longer and breakdowns were a common occurrence. Due to the significant upsize and lack of displacement due to the ground conditions, conventional pipe cracking was not a viable option.

We proposed Pipe Reaming as an alternative and were contracted to rehabilitate the existing 300mm sewer pipelines and upsize to a new 450mm HDPE pipeline.

We established our American Auger DD-10 HDD Rig, and our longest consecutive pull was 94 meters (Manhole to Manhole). We completed the 495 meters over 13 days.

Pipe Reaming is a modified HDD technique that simultaneously breaks the existing pipeline, together with removing surrounding ground material and installs the new pipeline. This ensures that the level of the new pipeline will not change from the old pipeline.

While we experienced some delays, Pipe Reaming proved to be a extremely competitive solution.
