Pressure sewer systems

Pressure sewer systems


GRP pipes are well suited for pressure sewer (forced mains) applications, where the durability of the material, ease of installation, and uninterrupted operation are critical. More information on GRP pipes for pressure sewer applications can be found here.

The available standard diameters range from DN 100 to DN 3000 in pressure class up to 32 bars and different ring stiffness classes. For water protection areas, double wall pipes are also available on request. GRP pipe systems have been tested and approved for sewer applications, meeting the most demanding criteria of many of the world’s leading authorities and testing institutes, including:

Due to its well-proven qualities and especially for the possibility of taking over, through restrained joints, the axial loads, the ductile iron pipes remain the first choice of engineers for the discharge lines in the treatment plants. Manufactured in compliance with the most recent standard SR EN 598, the ductile iron pipes in our offer are quality certified and tested by renowned European bodies.
