Real-timeWater Quality

sensors

Leak detection

• Transient water pressure changes measurement.• Water use forecast to detect anomalies.• Phone call/twitter monitor

• Close connection with customer interaction.

Water Quality

• Water Quality is measured afterwards (1-7 days). So our customers consume the water before it is properly tested for WQ changes in the distribution network.

• Our vision: we need real time online and inline solutions to monitor water quality and respond to problems before they affect customers.

• Our distribution network changes from a black box to sensor controlled.
