System Information

Transport and infiltrate

Transport and infiltrate

Wavin slotted twin-wall pipes allow water to infiltrate into the surrounding soil while transporting the flow. This reduces the rainwater load on the system endpoints, minimizing the risk of flood or back-up. Easy to inspect and clean, monitoring and maintenance are minimized.

Smart wall profile

Smart wall profile

Our slotted twin-wall pipes have a smart ridged wall profile which wins over smooth-wall pipes every time. The smart profile increases infiltration capacity, as proved both in our labs and in the field though independent testing.

Compliance

Compliance

Like all Wavin products, slotted twin-wall sewer pipes meet all relevant regulation and compliance standards. Made of virgin polypropylene, our pipes deliver fifty years’ service under even the toughest conditions.
