While the global population tripled in the course of the 20th century, the consumption of renewable water increased 6-fold. In the next 50 years, the world's population is expected to grow by another 40 to 50 percent. In combination with ongoing industrialization and urbanization, this growth will lead to a further increase in water consumption and have a noticeable impact on the environment.
Thanks to their easy laying, installation and maintenance properties, their light weight, resistance to incrustation and corrosion and their long service life, plastic pipes for drinking water transport are on the increase worldwide. Plastic pipes are hygienic, inexpensive and ecologically advantageous. Plastic pipes are with superior attributes, serving many purposes.
Preference is given to pressure pipes made of polyethylene, but also of PVC, as they possess the necessary chemical resistance and rigidity for underground laying. Both materials are long established in extrusion; PVC and HDPE pipes also comply with the stringent international quality standards and are recyclable.
