The toughest standards...

To ensure MetroSewer is up to the challenges of everyday, high-demand use, Naylor has put it through rigorous testing and standards. MetroSewer meets the requirements of both EN 13476-3 (Piping systems for non-pressure underground drainage and sewerage and WIS 4-35-01 (Specification for thermoplastics structured wall pipes – supplementary test requirements) guaranteeing resistance to internal puncture, water-jetting and the ability to meet longitudinal bending requirements. No matter the challenge, MetroSewer delivers. 

Versatility in mind

Both in construction and application, MetroSewer leads the charge in versatility and adaptability. Designed from the ground up for adoptable sewer systems with a wide range of lengths, bends and attachments available, MetroSewer is able to fully furnish all of your civils and groundworks requirements in both public and private operations.

Twin Wall Quality

Initially available in 150mm, 225mm and 300mm diameters, MetroSewer is built with Naylor's tried and tested twin wall polypropylene - offering substantial benefits including:

  • The flexibility to tolerate ground movement without damage, whilst withstanding the combined effects of backfill and loading
  • Fewer joints to reduce the likelihood of leaks and blockages
  • A high level of chemical resistance to the wide range of substances found in both effluent and contaminated soils
  • A smooth bore gives good hydraulic performance
  • WIS 4-35-01 certification for adoptable foul water sewers.
