Project deliverable Open Access

D6.1. Report on review and selection of new/ emerging monitoring technologies to be tested in T6.1.2.

Rieckermann, Jörg

In this deliverable D6.1, we describe the review of innovative sensors technology in the Co-UDlabs project and give details about the 8 selected sensors and the envisioned plan to test their performance. We applied a three-phased approach, where we first generated a comprehensive list of 55 sensors and digital monitoring technologies, e.g., data transmission and energy harvesting, which had a strong focus on online water quality monitoring. This list was subsequently narrowed down to a final list of 8 sensors which measure, i) coliforms continuously with in-situ fluorescence, ii) electrical conductivity with low-power, iii) water velocities with cameras, iv) NH4 and other pollutants with a submersible spectrophotometer, v) multiple pollutants with hyperspectral imaging, vi) polycyclic aromatic hydrocarbons PAH with in-situ fluorescence, vii) pipe condition, and viii) 3D sediment beds with LiDAR. Of those 8 instruments, 4 have a low technology readiness level (TRL) and have been selected for their potential to advance urban drainage research. In contrast, 3 other sensors have a TRL of 8 or higher, which means that, if tests are successful, they could readily be integrated into new monitoring services. In summary, we achieved a satisfactory balance between monitoring technology with the potential to advance urban drainage research and technology which can directly deliver added value to practitioners.

The final list of selected sensors is of special interest for work package (WP) 6 and WP9, to provide smart monitoring solutions and inform the transnational access activities. It provides the necessary input for Task 6.1.2. to test the sensors in the laboratory and under real-world conditions. It directly contributes to addressing the project goals defined in objectives No. 6.2 and 6.3 of the project proposal, as well as Main Objective 3, and to a lesser degree to objectives No. 2.2 and Main Objective 2.
