What is underground drainage?
This is the general term for sub-surface drainage. The system of underground sewage pipes and fittings transports foul water (also known as black water) away from your home or business and into the public sewer system. Underground drainage is also used to direct rainwater to a soak-away or in cases where you can prove there is no viable alternative, into the sewer.

This drainage system featuring robust PVC-u construction for pipes and fittings is a step up from older clay and plastic solutions. The smooth inner wall of the pipe promotes a much better flow rate while the robust construction resists degradation or collapse.

Under ground drainage pipes and fittings are instantly recognised because they are terracotta orange in colour. Built for compatibility with soil pipe systems installed above ground as well as manholes and inspection chambers, the available joiners and fittings include adaptors for full interoperability.
