The water and wastewater sectors face tremendous challenges to assure safe, cost-effective, and sustainable water supply and sanitation services. Detecting and treating emerging pollutants has become a critical need in these sectors. Innovative technologies could hold the key to solving these challenges. To support the market penetration and broader application of innovative methods and technologies in the water and wastewater sectors, DEMEAU cooperates with relevant policy makers, regulators, and standardisation bodies as well as with technology producers and users on the national and EU level. The DEMEAU newsletter delivers insights and shares developments within the DEMEAU FP7 project.
