This paper, published in the current issue of Trenchless Technology , reviews the successful use over the last 40 years of  PVC  sewer and sanitary drainage pipes. It cites various reasons for this success, including the superior, all round performance of PVC piping systems compared to the various alternatives. Equally important has been the ability and readiness of the PVC pipe and fittings industry to adopt new technology and design features relevant to the Australian environment, to invest in new production equipment and expand the product range. The use of material efficient pipe constructions and the ability to use recycled PVC from a variety of sources in the core of PVC sandwich construction pipes has led to an enhanced sustainability status of PVC sewer pipe. This, along with other environmental aspects such as low embodied energy, makes PVC the most sustainable material for sewer applications in Australia. For the full article, follow this link:
