Monitoring the water supply system in the city of Brussels



Located in the north-central part of Belgium, Brussels is the richest and most populous region of the country

The quality of drinking water can be negatively affected by many human activities, because of unwanted or deliberate pollution. These pollution events can take place at the resource (raw water at the catchment), but can also happen closer to the consumer, in the distribution network, and also at other locations in between these two extreme stages (e.g. water treatment, water storage).


Once the water is polluted, it will flow downstream to the consumer if no early warning has been raised. Since many customers are connected to the same drinking water network, the spread of any pollution can expose many customers at the same time, with potential health negative consequences.

Actions and expected results


The combination of the proposed aqua3S sensors brings new information, and are able to detect new substances and reduce false alarms. Placing miniaturised sensors in the distribution network helps to better protect consumers to deliberate contamination events, not only in the capital of Europe, but also to the water utilities in increase of true positives and decrease of false alarms.
