Underground Sewer Pipes

At Professional Building Supplies, we offer a comprehensive selection of pipes meticulously crafted to tackle the most demanding applications. These sewer pipes boast exceptional durability with reinforced walls, adhering to the stringent BS EN 1401-1 standards for strength, chemical resistance, and corrosion resilience. They are highly adaptable, ensuring a long-lasting and reliable drainage solution.

Finding the Perfect Fit: A Range of Diameters

To meet the unique needs of every project, we offer a wide range of underground sewer pipes in various diameters:

  • 200mm Drainage Pipe: A powerful solution for managing wastewater disposal. Compared to smaller options, 200mm pipes boast a significantly larger capacity, efficiently handling higher volumes of water.
  • 250mm Drainage Pipe: Ideal for larger domestic projects or commercial settings with increased wastewater volume, this size can accommodate multiple fixtures and higher flow rates.
  • 315mm Drainage Pipe: Suitable for commercial or industrial drainage systems, or large-scale residential developments that require the capacity to handle significant wastewater volumes.
  • 400mm Drainage Pipe: Our largest diameter pipes are built for heavy-duty applications in large industrial facilities and large-scale residential developments where substantial wastewater disposal is necessary.

Applications for Large-Scale Drainage

Large underground sewer pipes have a variety of applications, primarily focused on handling significant volumes of wastewater and stormwater:

Large-Scale Projects:

  • Commercial Buildings: Large office buildings, shopping centres, restaurants, and hotels all generate significant wastewater. Large diameter sewer pipes ensure smooth flow and prevent backups.
  • Industrial Facilities: Factories, processing plants, and other industrial settings often produce large volumes of wastewater with potential contaminants. These pipes can handle the increased flow and resist degradation from chemicals.
  • Large Residential Developments: Apartment complexes, student housing, and other high-density housing projects require robust drainage systems. Large pipes ensure all units can drain efficiently.

High-Flow Situations:

  • Wastewater Treatment Plants: These facilities receive large volumes of wastewater from various sources and require pipes that can handle the influent efficiently.
  • Stormwater Management: Large-diameter pipes are crucial for channelling significant rainwater runoff from large areas like parking lots, airports, and industrial sites.
  • Agricultural Drainage: In some cases, large diameter pipes are used to drain excess water from fields, especially in areas with high rainfall or clay soil.

Features & Benefits of Underground Sewer Pipes

Our underground sewer pipes are engineered to endure, offering a multitude of benefits:

  • Durability: Manufactured from high-density uPVC material, our underground drainage pipes are built to withstand the rigours of underground installation and resist corrosion for an extended lifespan. Our underground sewer pipes are certified to BS EN 1401-1, ensuring they meet the highest standards for quality and performance.
  • Strength: Large sewer pipes can handle significant pressure and weight from surrounding soil, ensuring they won't crack or collapse under load.
  • Leak-Proof Design: Featuring watertight joints and connections, our pipes minimise the risk of leaks that could contaminate soil or groundwater, protecting the environment. Our sewer pipes feature a unique captive lip seal within the sockets. This innovative design simplifies installation and ensures a secure, watertight connection every time. The seal prevents displacement, reducing the risk of leaks and ensuring a long-lasting, trouble-free drainage system.
  • Smooth Interior: The smooth internal surface allows for optimal wastewater flow, reducing blockages and the need for frequent maintenance, saving you time and money.
  • Chemical Resistance: The sewer pipes are resistant to common chemicals found in wastewater, preventing degradation over time and maintaining structural integrity.
  • Easy Installation: The underground sewer pipes are designed for ease of installation, often featuring solvent weld or push-fit connections that require minimal specialist tools, streamlining the process.
