How to optimise water recycling with sensors

Climate change often presents itself as an issue of water availability, putting the water industry at the heart of many climate change challenges. An increasing frequency of extreme weather events leads to more frequent periods of water stress and scarcity.

Reusing water reduces the pressure on water resources and recycled water forms a sustainable source of freshwater.

The required quality of recycled water depends on its intended purpose, e.g. to water parks in urban areas, to irrigate food crops, or direct potable reuse. The key to safe water reuse is a flexible and reliable sensor-based monitoring system which can match supply and demand, in terms of both water quantity and water quality.


Water scarcity affects almost one fifth of EU territory and at least 11% of  EU population: 56 million people (European Commission).


In the Mediterranean area, 20% of the population lives under constant water stress and, in summer, this rises to over 50% (European Commission).


By 2030, water stress and scarcity will affect 50% of Europe’s river basins (European Commission).


By 2027, the volume of recycled water produced in the United States is projected to increase by 37% to 6.6 billion gallons per day (WateReuse, USA).
