Drinking water is one of the goods that absolutely must be supplied. In fact, the general public sees this as something perfectly normal. Every installation needs to be safe, despite the damage that networks can suffer over their lifetime . These incidents are very varied and the normal supply of drinking water can be , severely restricted or even impossible.

When such an incident occurs, the distributor is obliged to guarantee a minimum supply of drinking water to the population (Ordonnance sur la garantie de l’approvisionnement en eau potable en temps de crise – OAEC) by implementing preventive measures.

Although there are regulations (laws, ordinances and directives) to guide local authorities (for example, the directive W1012 issued by the SVGW), the implementation of these preventive measures remains complicated and general, insofar as there is not always a clear vision of how the network will behave during such incidents.

We could then imagine a tool that could simulate various types of incident and their consequences on the network. This tool could also be used to improve the planning of preventive measures. Lastly, it could be used to define the investments needed to optimise water networks accordingly.
