Perforated or unperforated for soakaway and attenuation capabilities, twinwall pipes come in a variety of diameters. Twinwall pipes come in 150mm, 225mm, 300mm, 375mm, 450mm and 600mm diameters.

MDPE Water Supply Pipes

Whether it’s a blue water supply pipe or a black water supply pipe, all of the water supply pipes available from Drainage Superstore are manufactured from stress-resistant MDPE.

Bluewater pipes also have the added benefit of being able to be used for water service connections between mains and domestic residences. Water pipes come in 20mm, 25mm, 32mm, 50mm and 63mm diameters.
