Engineering Lifeline Utility Operators is a description for a multi-disciplinary group of companies and authorities that look after the roads, bridges, buildings, power networks, airport, port, major industrial plants, telecommunications and flood control structures.
The CDEM Act places a requirement on all engineering lifeline utility operators to ensure that they are able to function to the fullest possible extent, even though this may be at a reduced level, during and after an emergency.
Hawke’s Bay Engineering Lifelines Project
In November 2001, Engineering Lifeline Utility Operators in Hawke’s Bay, working under the guidance of the Hawke's Bay Engineering Lifelines Steering Committee completed a 3 year project to develop a detailed knowledge of all the utility networks that Hawke's Bay relies on for our everyday lives and business. They then assessed the risk these networks face from natural hazards in the region, including tsunamis, volcanic and earthquakes, storm and flood events..
They published their findings in a report entitled 'Facing the Risks' which is available online at the bottom of this page. You can also read a summary of the report pdf directly (940Kb).
But this report is only the beginning … Utility operators which have identified sections of their networks at extreme risk will now work to reduce that risk over the next several years.
The Hawke's Bay Engineering Lifelines Project, with support from the Hawke's Bay CDEM Group, will continue to assess the risks, as we get a better understanding of the hazards we live with, and find new and better ways to reduce damage to services and networks.

Hawke's Bay Earthquake 1931 - Land movement of the embankment has allowed the landspan to drop off the first pier support of the rail bridge, collapsing it to the ground. The rail track has remained suspended free of the fallen bridge
