Acceptable pipeline products that may be used for wastewater pipe work are:

Concrete pipes intended for wastewater applications shall be manufactured using a sulphate resistant concrete mix and, in addition to the standard thickness of concrete mix around steel reinforcing, the pipes shall have a 25 mm thick internal sacrificial lining of concrete mix. This reduced internal diameter shall be taken into account when determining the flow capacity of concrete pipes.
uPVC wastewater pipe may be used for pipe sizes ranging from 100 mm to and including 375 mm nominal diameter. Stiffness class SN16 pipes shall be specified in all cases.
