Underground Sewer Pipes

Large diameter underground sewer pipes are the workhorses of drainage systems designed to handle significant volumes of water. Here at Drainage Sales, we offer a robust selection of pipes built to tackle demanding applications. Manufactured to BS EN 1401 - 1 standard, these solid wall adoptable sewer pipes offer exceptional durability, strength, and resistance to chemicals and corrosion, guaranteeing a long lasting and reliable drainage solution.

  • Large-scale projects: Accommodate the extensive drainage needs of commercial buildings, industrial facilities, and large residential developments.
  • High-flow situations: Efficiently transport wastewater from factories, processing plants, and areas with heavy water usage.

Large Sewer Pipes for Every Project

To meet the unique needs of every project, we offer a wide range of underground sewer pipes in various diameters to ensure you find the perfect fit.

  • 200mm Drainage Pipe: 200mm diameter drainage pipes are a powerful solution for managing wastewater disposal. Compared to our selection of 110mm and 160mm pipes, 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: This substantial pipe size is suitable for commercial or industrial drainage systems 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 projects where substantial wastewater disposal is necessary.

Diverse Applications of The Sewer Pipe

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 that needs efficient removal. 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. They prevent flooding and protect infrastructure.
  • 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 built to endure, offering a multitude of benefits:


Manufactured from high density uPVC material, our underground drainage pipes are built to withstand the rigours of underground installation and resist corrosion for a long lifespan. Our underground sewer pipes are certified to BS EN 1401-1, ensuring they meet the highest standards for quality and performance.


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.

Installation Support: From Guides to Experts

Benefit from comprehensive installation guides and expert advice from our knowledgeable team. Whether you require assistance with selecting the right pipe diameter or navigating the installation process, we're here to help.
