Sewer Installation Time – Comparing PVC with concrete

 

Peter Verlaan

Papers # 2014 Chicago

Several scientific studies underline benefits that plastic sewers have over traditional materials like clay and concrete. A few scientific studies which confirm that statement are for example:

  • Teppfa SMP project The SMP [explanation?] project showed that plastic systems have 75% fewer leaks than concrete. The full story can been found on the Teppfa website.
  • EPD Studies On average, plastic pipes have 30% less impact on the environment than alternative materials. Compared to concrete , plastic sewers have a comparable environmental impact. The full story can be found on the Teppfa website.
  • Lifetime expectancy PVC sewers have a lifetime expectancy of at least 100 years. The full story can be found on the Teppfa website. (Lifetime expectancy study for Polyolefins is under construction).

The installation time is, in these studies, an unimportant parameter which is especially for the EPD study has been set equal for sewer and concrete. Assumptions 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. By using parameters out of the three scientific studies mentioned above as the starting point, we managed to prove by a non-scientific (field test) study that contractors can save installation time by using thermoplastic sewer pipes and fittings.
