Underground Drainage Pipe FAQs

What is an Underground Drainage Pipe?

Arrow down

An underground drainage pipe is a length of hollow tube, usually plastic and between 110 mm and 160 mm in diameter, designed to carry wastewater away from properties and to the nearest sewer network. They form part of extensive networks held together by underground drainage fittings. 

Why Choose Plastic (uPVC) For Underground Drainage Pipes and Fittings?

Arrow down

Plastic is the new industry standard thanks to a range of benefits it offers:

  • Lightweight and easy to handle: Plastic is light, making it easy to transport, handle, cut and install.
  • Cost-effective: Its lightness also makes plastic cost-effective to transport and it’s usually less expensive to produce too.
  • Durable and corrosion resistant: Plastic is highly durable and resistant to corrosion, lasting as long as 50 years or more with proper installation.
  • Eco-friendly: Their long lifespan and recyclability make plastic pipes an eco-friendly choice. 

What is The Best Pipe to Use For Underground Drainage?

Arrow down

The best underground drainage pipe will vary by application. Different situations and drainage needs call for different sized pipes. For example, 110 mm drainage pipes and fittings are well suited to smaller domestic applications, whereas 160 mm pipes are more appropriate for larger domestic and smaller commercial properties.

How Deep Should an Underground Drain Pipe be?

Arrow down

The required depth for drainage pipes will vary based on type and local regulations. For example, sewer pipes will typically be placed deeper than domestic drainage. For domestic drainage, a depth of between 600 mm and 900 mm is common, to protect the pipes from freezing and shield them from surface disturbances such as traffic. 

Do Underground Drainage Pipes Comply With Industry Standards?

Arrow down

Every underground drainage pipe we sell carries a BSI Kitemark and adheres to the relevant industry standards, including being manufactured under BS EN ISO 9001:2015 and tested to the requirements of BS EN 13598-1:2010, BS EN 1401-1:2009 and BS EN 13476-2:2018. Along with the pipes we source from our manufacturing partners, our own brand of Vision Drainage complies with all industry standards.

Are the Drainage Pipes Compatible With Other Drainage Systems?

Arrow down

Yes, our drainage pipes are compatible with a host of other drainage systems we supply. Because our underground drainage pipe range features several different sizes and is made from uPVC, the pipes can match different-sized openings, and can also be easily cut to accommodate precisely measured connections to drainage systems like inspection bases and risers, sewage treatment systems. You can also use our flexible, underground drainage adaptors to simply connect two different-sized drainage pipes together.

Is Bulk Pricing Available on Underground Drainage Pipes?

Arrow down

What Can Our Underground Drainage Pipe Systems Be Used for?

Arrow down

Underground drainage pipe systems, including socket bends, are used to move wastewater, rainwater and excess surface water safely away from buildings and outdoor areas. These pipes prevent flooding, manage foul and surface water separately, support soakaways or mains drainage connections, and help protect foundations, landscaping and infrastructure. Our pipes are key for efficient water management in domestic, commercial and industrial settings.
