Concerns Surface From Polypropylene Pipe Installations
In some U.S. markets, contractors and engineers are being solicited to experiment using polypropylene (PP) pipe in storm water projects. Generally, when compared to reinforced concrete pipe (RCP) and other flexible materials, there are very few PP storm pipe installations nationwide. Civil engineers and underground utility contractors know very little about PP storm pipe, and the history book of successful PP pipe performance is yet to be written. While consistent, successful performance of PP storm pipe remains to be proven, there are published articles available to engineers that are interested in learning more about the PP storm pipe material, design, and installation characteristics. Recently, some interesting reports - stemming from actual installations - have emerged to raise concerns and doubts about PP pipe.
