In September 2010 a 7.1 magnitude earthquake struck near CHC in the South Island of New Zealand. The earthquake's epicentre was 40 kilometres west of CHC and the result of the quake was widespread damage and power outages. Aftershocks continued well into 2011, with the most devastating being a magnitude 6.3 on 22 February 2011, which caused the loss of life, extensive damage to the city of and left many people in need of assistance.
The city’s wastewater infrastructure, which had been compromised since the 2010 quake, had suffered numerous collapses in conjunction with extensive silt build-up and required immediate attention. A taskforce, consisting of several contractors from around , was mobilised in March with Kembla Watertech sending over a Combo Unit truck and a Jetting Truck.
A small army of Kembla's trenchless technology pipeline rehabilitation experts, headed up by from Kembla Watertech's Northern Division, have been living and working in the earthquake affected region since March, and due to the collapse of many buildings and the resultant shortage of accommodation, have been calling campervans and RV’s home since arriving.
Trenchless technology used by Kembla Watertech in Christchurch includes surveying and cleaning sewers, bringing the infrastructure back to use for Christchurch's residents.
