June 2010: Battling the cold to complete a $1.6million sewer contract in Dunedin
Interflow has endured working in below freezing conditions whilst carrying out a major sewer rehabiliation contract in Dunedin on New Zealand's South Island. The relining work was done with Expanda. To deal with the extremely cold conditions Interflow fabricated a thermal cover and support frame to keep the spool of Expanda PVC profile at 15°C whilst it was on the truck and used a heater for warming the profile up as it was being fed into the winding machine.

May 2010: Interflow renews egg shaped sewer in Adelaide
Interflow has successfully renewed in total 484 metres of 525mm x 350mm egg shaped sewer and reinstated a total of 28 junctions as part of a sewer rehabilitation contract in Adelaide. This was the first time that Interflow had relined an egg shaped pipe of this size. The project was made all the more challenging because the concrete egg shaped sewer runs below a busy arterial road. To minimise disruption to the local community and road users Interflow's crews worked over successive shifts on weekends and at night to complete the relining project.
