At the 17th Plastic Pipes Conference, 2014, Chicago, Illinois, USA, The European Plastic Pipes and Fittings Association (TEPPFA) presented a paper using previous scientific papers as the starting point to prove by a non-scientific (field test) study that contractors can save installation time by using thermoplastic sewer pipes and fittings.
The previous studies reviewed were the SMP project, EPD Studies and Lifetime expectancy studies all carried out by TEPPFA.
Assumptions made in these previous research studies about the speed of installation were: “It has long been clear that installing a plastic sewer system can save time over the installation of a concrete sewer system”, but never investigated. These studies were not focused on the installation time during their research.
The results of the field testing found that the PVC pipe installation was over 30% faster (3 hours and 19 minutes vs 5 hours and 12 minutes) than the same size concrete.
That’s a time saving of 1 hour and 53 minutes on a sewer PVC pipe installation of two chamber trench 90 metres long, 2 metres deep with a diameter of 300mm.
Over the span of a major sewer pipeline installation, this time saving represents extensive cost and time savings. This result would also be applicable to installation of a stormwater pipe.
The field testing was documented by a research paper
