Diamir Manholes – Reliability and Durability in Sewage Systems

Diamir manholes are a comprehensive solution for the construction of gravity sewage networks for various purposes – sanitary, rainwater, combined, industrial, and drainage. This system offers a wide selection of elements, allowing adaptation to the specific requirements of each project. The PP 800x315 shaft, which is an element of this system, is a key component in building an effective and long-lasting underground infrastructure.

Construction and application of the collective shaft

The PP 800x315 shaft is a collective element, without slope, designed to connect a riser ring with a diameter of 800mm with smooth inlet pipes with a diameter of 315mm. Its construction allows for effective collection of wastewater from several sources and directing it to the main collector. Made of polypropylene (PP), it is characterized by high resistance to chemical corrosion and abrasion, which guarantees a long service life even in difficult environmental conditions. Available in orange color (Diamir 800), it facilitates identification and location in the sewage network. This model is supplied without a gasket – its selection remains with the installer, allowing for optimal adaptation to specific installation conditions.

Advantages and benefits for professionals and users

• Durability and resistance: Polypropylene provides high resistance to the action of aggressive chemical substances present in wastewater and to mechanical damage. This translates into minimal need for repair and replacement of system elements.
• Versatility: The shaft is compatible with riser rings with a diameter of 800mm and smooth inlet pipes with a diameter of 315mm, which facilitates integration with existing infrastructure or construction of new networks.
• Tightness: A properly selected gasket ensures a tight connection of the elements, minimizing the risk of leaks and environmental pollution.
• Easy installation: The light weight of the shaft facilitates transport and installation, shortening the investment implementation time.
• Compliance with standards: Diamir manholes meet the requirements of PN-EN 13598-2:2020-11 and have a National Technical Assessment (KOT) issued by the Building Research Institute, the Road and Bridge Research Institute and the Railway Research Institute, which confirms their high quality and safety of use.
• Possibility of use in various configurations: “Blind” shafts can be used as sewage tanks or pumping stations, expanding the scope of applications of the Diamir system.
• Resistance to loads: The shaft exhibits high mechanical strength, meeting the requirements for vertical and horizontal loads in accordance with PN-EN 13598-2:2020-11.
• Smooth surfaces: Both internal and external surfaces are smooth and clean, which minimizes wastewater flow resistance and facilitates visual inspection.
