Today, in some parts of Europe plastics pipes and fittings are considered as mature products which have obtained an established position in underground applications. However, in others due to their flexible nature, their use is still sometimes questioned. This paper describes the actual performance of plastics pipes of different materials in different applications, and in a wide variety of buried conditions. To this end, use is made of an extensive computerized data base called "PiPeru, in which practical data obtained over a period of 25 years by different European companies and authorities has been collated, compared and evaluated for the first time. The majority of this data has remained unpublished until now. The data have been correlated and the outcome of this is presented. The facts as found are discussed and from this conclusions are drawn.

The type of problems encountered in existing pipelines are presented in this paper, together with the available methods to rehabilitate them. In the majority of the cases plastics are nowadays applied, either to replace the existing ones, or to renovate them by lining. The latter is increasingly gaining...

One of the main reasons that plastics have not found more extensive use in non pressure sewer schemes has been concern about the long term deformation characteristics of the pipeline. In order to investigate this phenomenon the flexural behaviour of u W C sewer pipes installed in Western European countries, including...

The main concern over the behaviour of buried plastics pipes is the occurrence of deflection. Theories are useless if not checked by field measurements to remove uncertainties, Over the last 15 years. 25 km of pipeline in 600 different sections have been measured in 5 West-European countries in quite different...
