Turbo installation for Ridgistorm-XL

Posted: Monday 23rd July 2012

Polypipe, the UK’s leading manufacturer of plastic sustainable drainage and water management products, has seen its Ridgistorm-XL large diameter pipe utilised as a below ground water attenuation tank, designed specifically to supply water to a fire sprinkler system in West Yorkshire.

This application is a first of its kind for the market-leading Ridgistorm-XL system with the installation being carried out by main contractors Shanco Construction at Turbo Technologies in Huddersfield.

Ridgistorm-XL was specified for the project due to the flexibility of the system’s design and Polypipe’s expert water management solutions teams’ ability to pre-fabricate vital inspection points into the tank design.

Manufactured at Polypipe’s own water management solutions in-house fabrications department utilising 135m of 2.1m diameter pipe, the tank was designed to exact specification, including a series of pre-fabricated fittings including two T-junctions and six elbows featuring turrets.

“The site constraints during this particular project threw up some interesting challenges for us,” comments Declan Armour at Shanco Construction. “As the tank was installed on a live site with a construction footprint of just 700m², speed of installation was essential in order to negate any potential health and safety risks associated with prolonged installation. However, the light-weight nature of the plastic pipes and the use of pre-fabricated fittings ensured that installation occurred quickly and with minimal disruption.”

Polypipe’s water management solutions technical team were able to carry out structural calculations to value engineer the project, determining that a stiffness classification of 1kN2 would be suitable for the tank. Shanco’s installation team were also trained in how to join the pipes on-site using Polypipe’s electro-fusion welding technology, which further contributed to the speed of installation.

Emma Thompson, Marketing Communications Manager at Polypipe, comments: “The adaptability of our Ridgistorm-XL large diameter pipe system enables us to create bespoke solutions to many applications. This project is a great example of the capabilities and performance of the product.

“Direct benefits to Shanco Construction on-site included speed of installation and improved health and safety benefits when handling the product. Further to this, there was a reduced need for heavy plant on-site for the installation, bringing further cost and time savings.”
