The device is installed directly in the upper part of a sewer system pit and monitors water quality continuously, providing alerts if programmed limits are surpassed.

All work is resources saving and simple due to its autonomous and independent system, non-intrusive in the flow and with easy maintenance. Smart Cities trend drives society to a greater amount of sensors for real time information and convenient alerts.

Networks managers take advantage of gathered information for increasing their performance and reducing management costs. Treatment plants are prevented from suffering damage by spills or other events.

Data analysis and correlations will lead to the prevention or mitigation of undesired events effects.
