You are...

If you are working in the polymer industry or in sewage and drainage water management. Or if you are a plastics pipe manufacturer, a constructor, or perhaps an end users. Then you know that the management of water sewage and drainage is very important, especially for urban societies. In many cases the surplus of rain water, process water or sewage water has to be transported away from streets and buildings. Modern piping systems are increasingly made of thermoplastics, like polyethylene (PE), polypropylene (PP) and PVC. For large diameter sewage and drainage pipes also glass reinforced plastics (GRP) are used.
