The broad challenge of this research is to develop new control tool for providing infrastructure services in a sustainable manner. In the last years some attempts have been provided to introduce smart control tools for water distribution system, as a part of critical infrastructure maintained in megalopolises and rural areas. Smartening Critical Infrastructure introduces inter-dependencies that increase vulnerability, as they give rise to multiple error propagation channels from one infrastructure to another. Such phenomena provide impact on environment, efficient usage of natural resources and sustainability. In this paper, starting from the state of the art and current best practice [14] we identified the most suitable set of metrics for the quantification of the interdependencies among Power, ICT and Water distributed network infrastructures. Moreover, we develop a simulation model based on state of the art theories and technologies to study the real case of Latvian city Ventspils. The proposed approaches for the analysis of critical inter-dependencies could be useful for practical adoption of methods and metrics for a broad number of Critical Infrastructures operators and stakeholders.
