An increase in routes and passenger numbers meant that Manchester Airports Group Plc (MAG) required a new shuttle bus route and 9,000 extra car parking spaces at the already popular Manchester Airport.
Working closely with the project’s contractors, Polypipe was tasked with engineering a surface water drainage system which would enable the facilities to remain operational in the event of a storm, thus minimising disruption to travellers.
Polypipe engineered a stormwater drainage system with pipework made from Ridgistorm-XL large diameter pipe and Ridgidrain and Ridgigully products.
The system captures and carries surface water from the new car park through a number of drainage runs and prefabricated chambers before entering the existing sewer run on the main link road between the car parks.
Polypipe manufactured and supplied over a hundred Ridgistorm-XL modularised chambers for the project, in diameters ranging from 900mm to 2700mm.
Polypipe also designed a number of RIDGISTORMSeparate catchpits, RIDGISTORMCheck orifice plate flow control chambers and RIDGISTORMControl chambers with flow control valves and penstocks, to restrict the flow of water downstream and avoid overwhelming the sewer system. A flap valve within a 1500mm RIDGISTORMControl chamber was used to prevent water returning after being dispelled.
As Polypipe’s plastic products are lighter in weight than traditional concrete counterparts, smaller lifting equipment could be used during the installation phase, offering a number of cost saving benefits. Polypipe manufactured its chambers to include lifting points, which made lifting during installation quicker and safer.
A key consideration for MAG was ensuring that the specified system could be easily sourced, and that guidance from the manufacturer would be readily available. Polypipe’s complete range of solutions, along with the expertise of its team, meant that a full package of bespoke pipes and chambers could be sourced and installed to schedule.
