Smarter water management through
sensor-based networks

With Thanks to Dr. Matt Dunbabin and the Autonomous Systems Lab
Australia is a big country with a small population (2.833/km2)
89% of people live in urban areas.
The rest don’t.
Australia is a dry country and water is a major issue
Australia is a major exporter of primary produce and so water
Some other interesting points
A National Broadband Network will be rolled out in
Australia and will connect all Australian premises
with fibre or wireless services
Total value is A$43Bn (Eur 29Bn)

Mission : Provision of high-quality drinking water
CSIRO : Smarter water management through sensor-based networks
Paradigm Shift
“Real Time” Water Quality Monitoring
• 1 Sample / day (week)
• Labour intensive
• Weather dependant
• Bad temporal resolution
• 1 Sample every 2 hours
• High cost
• Bad spatial resolution
• 1 Sample / minute
• Low cost
• Robust (redundancy)
• High spatial resolution
• High temporal resolution
