The Wellington region in Aotearoa New Zealand experiences regular earthquakes and is vulnerable to potentially lengthy outages of wastewater and road networks. Recognising this, a collaborative project was conducted between scientists and Wellington’s water network management company, emergency management body and regional public health authority to create a coherent emergency sanitation plan for a major wastewater system failure.

 ‘Planning Emergency Levels of Service’ (PELOS) are goals for the delivery of infrastructure services following a major hazard event, such as an earthquake or flood. This paper presents an operationalised PELOS framework for the Wellington region based on interviews with emergency and critical infrastructure managers and discusses important changes from the preliminary to the operationalised framework. 

How can emergency management teams communicate to potentially impacted communities what a major event causing infrastructure outages might mean for them, and what they can do to prepare? In this paper we describe the process of creating a webtool for end users to visualise infrastructure outages that the Wellington region of New Zealand would face following a rupture of the Wellington fault.

Wairarapa Engineering Lifelines Association (WELA) Risk Framework

The resilience of selected local roads in the Wairarapa region has been assessed by consideration of the extent and duration of loss of functionality in the aftermath of a large storm and a large earthquake.

To ensure rapid economic recovery following a major earthquake in Wellington, it is imperative that core infrastructure is as resilient as possible - this is the focus of the Wellington Lifelines Project. 

This report pulls together information gained from recent work carried out by the transport infrastructure providers.

This report provides a summary of likely restoration time for key lifeline utility services, following a major earthquake involving a rupture of the Wellington Fault.

This report documents the findings from a trial of emergency compost toilets conducted by WREMO in 2012. The trial demonstrated that compost toilets are a viable toilet option in an emergency where sewerage systems are disrupted.
