Meters measure water consumption at each household.

In the network, other meters and instruments provide real-time readings on the flowrate,

pressure, vibration levels and water quality; and detect any leaks or changes

in quality as soon as they occur.

These instruments transmit data via communication systems.

This is what makes drinking-water systems smart.

All the data converges at a centralized control center.

These control centers combine and analyze the data

to provide insight about operations or events.

This way, analysts have a global view of the network in real-time.
