The deployment of smart metrological procedures and practices as well as challenging operating conditions for urban water monitoring require ever more efficient tools. In this context, the OTHU IField Observatory for Urban Water Management) rehabilitated its field monitoring stations. This paper aims at demonstrating benefits from innovative OTHU's monitoring stations regarding the reliability of collected data and the decrease of maintenance costs. The current technology offers real opportunities in terms of reduced costs, reactivity and improvement of data pre-processing. Each station produces approximately 12,240 data per day, ensuring continuous monitoring of stormwater quantity and quality in urban environment. The long term monitoring of the dynamics of hydrologicat processes requires 24/7 operational and reliable equipment and devices. The new OTHU monitoring stations are reliable and provide representative data of higher quality than the previous ones.
