The development of gas, water and sewerage networks greatly enhanced city life in the late 19th and early 20th Century providing much needed street lighting and dramatically reducing water borne disease. Understandably in many European cities these underground piping systems are now showing serious signs of their age. In Italy as in other European countries the government has been reluctant to invest in these systems – at least until the situation becomes critical. This has resulted in high water leakage rates in some areas which are now compounded by water shortages due to the increasingly dry, hot summers. An attempt is being made to address this situation by representatives of the complete “Pipe Chain”, from raw material producer, pipe & fitting makers, utility companies through to consumer representatives. Conceived at the last Plastics Pipes Conference in Baveno this group have tried to understand the needs and started to formulate some proposals to improve the infrastructure that can be discussed with Government Departments and other organisations. This paper describes how this process has developed and describes some of the proposals initiated so far which may provide a useful model for other countries to follow.

In Europe polyethylene (PE) has been chosen almost exclusively for gas mains for many years because of economic, technical and safety reasons but in the water industry a number of different materials are still used for pressure water mains. Indeed at sizes above 355mm (14 inch) most new large diameter water mains are...

Polyethylene has been in use for the manufacture of piping systems since the sixties and has progressed in its property spectrum not only in terms of resistance to pressure, but also both in terms of resistance to Rapid Crack Propagation and to Slow Crack Growth. In terms of processing friendliness however, further...

The key reason for investment in technology should be obvious – it is for business growth. The main volume products - PE and PVC are at a similar stage in the business cycle, where formerly rapid growth has decelerated and is in the doldrums with declining prices – the classic signs of a mature market. Meanwhile there...

Electrofusion fittings have now been widely accepted within the European Gas Industry for jointing polyethylene pipe. with a high potential demand for electrofusion couplers, Wavin applied its plastics process knowledge to develop an efficient and cost effective co-extrusion manufacturing technique. In this method a...

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...
