During construction of the Rugby Western relief road a temporary pipework solution was required to divert a critical 600m diameter foul rising sewer running underneath Parkfield Road, allowing construction of an interconnecting tunnel built between two disused quarries.

The Rugby Western Relief Road was built to relieve traffic congestion in and around Rugby due to the on-going and future residential and industrial development in the town over the coming years.

As part of the on-going works, Carillion the main contractor needed to divert certain major services, including gas mains, electric cables and combined foul sewer, whilst the construction took place. Pump Supplies were approached to provide a temporary pipeline solution to the diversion of a critical 600mm diameter foul rising sewer running underneath Parkfield Road and to allow construction of an interconnecting tunnel to be built between two disused quarries in total a 280m length.

This would allow the nearby Paynes Lane Pumping Station to work as normal through Pump Supplies’ hired rising main, so Carillion could replace the existing permanent rising main which connects Severn Trent’s Newbold Sewage Treatment Works- some 1.5km away on the outskirts of Rugby.

THE CHALLENGE: To provide a temporary 600mm pipework solution at short solution including a wide variety of bend and special fabrications, including special considerations for potential damage caused by vandalism.

THE SOLUTION: Delivery of pipework including many on-site fabrications to allow the pipework to negotiate many obstacles.

Overall the job took just 3 weeks to construct, well within the timeframe given by Carillion. Commenting on Pump Supplies involvement, Carillion Works Manager Tom McPhearson, ‘This was a very bespoke temporary pipeline diversion job. Pump Supplies were able to fulfil its requirements successfully, enabling us to complete our work to the new rising main satisfactorily. The speed in which they found a solution to the problem and overcame challenges that the location, pipework configuration and ground conditions posed were particularly impressive’.
