Beban, J.G.; Stewart, C.; Johnston, D.M.; Cousins, W.J. 2013 A study of the role of rainwater tanks as an emergency water source for the Wellington region following a major earthquake on the Wellington Fault. Lower Hutt, N.Z.: GNS Science. GNS Science report 2013/16 17 p.

Abstract: The Wellington region is highly vulnerable to large earthquakes because it is bisected by large active faults. It is also at risk of being isolated due to the disruption of supply lifelines. In particular, the bulk water supply pipelines cross the Wellington Fault at several different locations, implying that severe disruptions to reticulated water provision to households are highly likely as a consequence of an earthquake on this fault. This is particularly the case for Wellington City because of its high population and isolation from local sources of water. The purpose of this study was to explore the role of rainwater tanks in providing an alternative source of water to households in Wellington City in the event of a large earthquake. (auth)
