This system can, and has been used as Carrier or attenuation drainage at the Crest, 6ft, 10ft or Cess to efficiently remove water from waterlogged areas along an embankment or track.

This easily installed modular drainage system is lightweight and easy to maintain along its entire length without the need for heavy lifting equipment, Road Rail Vehicles (RRVs), cameras or jetting equipment. The system offers the ability to remove or store greater volumes of water over pipe in narrow areas where space is a challenge. This is achieved through the versatility of three different sizes and the ability to gain volume through depth over width.
