NETWORK MONITORING
Comprehensive monitoring of the distribution network has been made possible by
low cost battery-powered communicating sensors. This thought piece challenges
thinking about how network managers and their bosses can get the most out of the
opportunities this creates.

network monitoring with SCADA, even to create one only when it’s needed. It is not a good idea to use
monolithic technology for the water industry. But is battery power to support a system that is:
this the right thing to do?

only to send back data when it can be used effectively.

for its cost.
Most Control rooms are already drowning in alarms. Before we add to their burden we would do well to ensure
that both Control and the Network move along this path in relation to the tsunami of data that is becoming
available:
If planes can fly themselves with a pilot only as a supervisor and emergency stand-in then it should be possible
for water infrastructure to operate in the same way.
Whither Control?
Yes, that’s right. There won’t be a control room. A meeting room will be requisitioned ad hoc.
i2O’s network monitoring solution iNet therefore has these key features:
1. i2O loggers by default return data daily and on 4. Enables threshold alarms to be set and reviewed
breach of a threshold alarm which also trigger SMS or
email alerts (the system is fully configurable for data
return frequency nonetheless).
What should we conclude? The distribution network and Control are similar but not the same. It should be
possible to integrate them more closely but unwise to merge them. There are still many opportunities for
improvement in both, and further advances in enabling technology to come.
