Sensor for city’s network Some issues Most common sensors are non specific Conductivity, pH, Turbidity, UV-visible absorption, Chlorine, Oxygen Limited number of available location in cities Limited space available underground Electricity availability Significant electrical consumption Costly : investment, maintenance, communication
Sensor for city’s network Need more development
Rethinking IT architecture = €€
EWS for city’s network Rough estimate But for low probability events Investment cost : ± 5 M€ Maintenance cost : > 0,5 M€/year But for low probability events At the moment sensors, infrastructure needs and global cost are evaluated
