HDPE Storm & Surface Water Drainage Pipe (BS EN 1401)

Engineered for durability and reliability, this HDPE storm and surface water pipe is the standard solution for non-pressure underground drainage and sewerage systems. Manufactured in strict accordance with the British Standard BS EN 1401, it ensures consistent performance for applications both outside the building structure and for buried lines within the building envelope.

The pipe features a plain (smooth) internal surface which minimizes friction loss and prevents sediment buildup, ensuring efficient flow rates even during peak storm events. Its high-density polyethylene construction provides exceptional resistance to chemical corrosion, root intrusion, and ground settlement, making it a long-term investment for municipal and private infrastructure projects.

• Complies with BS EN 1401 for non-pressure underground drainage and sewerage.
• Smooth internal bore reduces clogging risks and maintains optimal hydraulic efficiency.
• High resistance to environmental stress cracking and chemical attack.
• Lightweight design facilitates easier transportation and on-site installation.
• Flexible enough to accommodate minor ground movements without fracturing.
