As a result of increasing interconnection and information the world has never
been so vulnerable. New and changing vulnerabilities have arisen from a more
open global society, complex technological systems, greater dependency on
electronic information and communication systems, integrated systems of food
production and supply, and interconnected large transport systems. Inactivation
of a few pivotal major points and functions for a long time – irrespective of
whether it is a result of a terrorist attack, sabotage or a technical failure – could
bring a large breakdown.
The paralysis or destruction of the most critical infrastructures could weaken
the defensive or economic safety of a country. These infrastructures include
telecommunication, power and transport networks, banking and financial
services, state and emergency services and, last but not least, water supply
systems. For the above reasons, a great deal of attention is being given to
the preparation of preventive measures, safety plans and risk analyses of water
supply and sewerage system vulnerability because they provide both a basic
human need and are important for the health of towns and villages.
