Linwood Avenue, Christchurch, 2013

This was an emergency repair job. The 1200mm diameter pressure sewer had burst at a depth of 5m deep on a 90º bend. To repair it we had to sheet pile around the break, over-pump the Linwood Creek, design a 1200mm diameter 90º compound bend with a 30º vertical made out of fibreglass. From start to finish this repair took us three weeks. During this time the entire catchment area had to be diverted.
