The line, which had been closed for over 30 years, and a new station and train line were constructed to provide better access for commuters as well as to supply coal to a power station.
150mm, 500mm half-perforated Ridgidrain pipe and 900mm Ridgistorm-XL half perforated pipe were installed and utilised for drainage on either side of the railway track. The pipes run into a series of catchpits, positioned at intervals along the track, in various depths and outlet designs, which will stop the overflow of rainwater. The catchpits were manufactured at Polypipe CGU’s 33,000 square metre in-house fabrications facility and delivered ready to install, saving the contractor valuable time on site.
Ridgidrain is the market leading structured wall surface water drainage product and is the complete technical and commercial answer to all non-pressure, surface and sub-surface water drainage applications. The Ridgidrain range is often preferred to traditional alternatives as they can typically be up to 94% lighter than a pipe of equivalent size.
Warren Hawkins of Edmund Nuttall was very pleased with the performance of Polypipe CGU’s products, saying: “We worked closely with Polypipe CGU to enable them to meet our requirements on this project. Both their Ridgidrain and Ridgistorm-XL pipe and catchpits have been successfully utilised for a number of railway drainage applications in the past, so we were confident that these products would deliver the specified performance requirements.
“When working on a railway line, it is essential to install a product that withstands some ground movement and differential settlement, which was a significant factor in us installing the Ridgidrain drainage system.”
