essential systems upon which the well-being and functioning of societies depend. They deliver a service or a good to the population using a network, a combination of spatially-distributed links and nodes. As they are interconnected, network elements’ functionality is also interdependent. In case of a failure of one component, many others could be momentarily brought out-of-service. Further problems arise for buried infrastructure when it comes to buried infrastructure in earthquake and liquefaction-prone areas for the following reasons: • Technically more demanding inspections than those required for surface horizontal infrastructure • Infrastructure subject to both permanent ground displacement and transient ground deformation • Increase in network maintenance costs (i.e. deterioration due to ageing material and seismic hazard) These challenges suggest careful studies on network resilience will yield significant benefits. For these reasons, the potable water network of Christchurch city (Figure 1) has been selected for its well-characterized topology and its extensive repair dataset.

Workers repairing the James Hight building at the University of Canterbury, seen from inside the library. The photographer comments, "Yet another change of workplace for our E-Learning group, as the University juggles people and buildings to carry out earthquake repairs. Our area looks over a central roof space that has seating areas. It may be a while before we're allowed out there though".

An aerial photograph of the PricewaterhouseCoopers building. The photograph is captioned by BeckerFraserPhotos, "PricewaterhouseCoopers building at 119 Armagh Street. Its status is uneconomic to repair, so it will be demolished. Copthorne Central is visible behind it and will be staying".
