Product Details

Osma TwinWall is specifically designed to handle the collection and disposal of surface and sub-surface water. Manufactured from either Polyethylene or Polypropylene, the system is available in diameters ranging from 150mm up to 600mm. A comprehensive range of fittings are available in all sizes.

The WavinTwin system is designed for use as a direct alternative to all non-pressurised gravity drain/sewer systems except where Local Authority adoption is necessary.

Typical applications include:

• Highway filter and carrier drains

• Rail track drainage

• Unadoptable surface water drains e.g. on industrial or commercial developments

• Golf course land drainage
