Butler, A. 2015 Christchurch residents water use in the weeks after the 22nd February 2011 earthquake : initial report from existing data sources. Lower Hutt, N.Z.: GNS Science. GNS Science report 2015/22 ii, 20 p.
Abstract: The 22nd February 2011 Christchurch earthquake caused widespread damage to the city including significant damage and disruption to the city’s essential infrastructure. The Civil Defence and supporting agencies and authorities responded to the seriously damaged and non-functioning infrastructure by supplying residents with essential alternative water supplies. There is very little documented on how residents responded to the disruption to reticulated water supplies and the adequacy and use of alternative water sources in the immediate weeks after the earthquake. This report draws on existing datasets on peoples’ experiences of the Canterbury Earthquake Sequence to derive some preliminary observations about residents’ response to non-functioning infrastructure and their consequential activities related to sourcing and using alternative water supplies. Initial results show that while the water needs of Christchurch residents were met, this was done through a variety of official supplies and emergent networks and sources. The report contributes the first preliminary documentation and analysis of the post-earthquake water related activities and recommends further analysis and investigation. (auth)
