Increased safety for pipe systems for potable water

The quality requirements for drinking water are defined in various international standards. It has become common practice to disinfect potable water in order to eliminate possible health risks. Disinfection with chlorine has been proven as reliable and cost-effective, and has therefore become the most common treatment. An important consideration is how the chlorination might affect the service life of pipe systems. A project has been initiated to research the long-term effects of chlorine on plastic pipe systems. This project is being organised by two professional institutions renowned for testing methods for plastics: the Süddeutsche Kunststoff-Zentrum (SKZ), Germany, an independent testing and research institute for plastics and plastics products, and IPT Institut für Prüftechnik Gerätebau GmbH & Co KG, a developer and manufacturer of test equipment for the plastic pipe industry.

IPT’s specialists are designing and manufacturing suitable state-of-the-art equipment to provide the project with a test unit that will produce reliable results. Using this equipment, a sustained pressure test on pipe systems can be performed over a range of temperatures with chlorinated medium. During the entire test duration the pH level and free-chlorine concentration of the test fluid is measured and regulated to the predetermined parameters, while data is continuously monitored, collected and documented by means of a data logging system. SKZ is contributing its expertise in the area of pipe systems for potable water supply and house installations. The company has many years’ experience of testing, supervising and certifying products and companies in the plastic industry. With the newly developed IPT unit, important knowledge will be gained

The project will be supported directly by the German Federal Ministry of Economics and Technology (BMWi).
