Monitoring — Constructed wetland

To assess the hydraulic performance and long-term pollutant retention of the filter trench and bioretention area, a monitoring strategy has been implemented. This approach is essential to better understand how the system works, quantify its efficiency, and generate useful insights for future applications in island environments and ecologically sensitive areas.

The monitoring programme includes three main components:

Hydraulic monitoring will rely on flow meters installed at the inlet and outlet, enabling analysis of the water managed by the system and estimation of its retention and filtration capacity. In addition, water levels within the SUDS will be tracked, as this is a key parameter for evaluating system response to rainfall events and performance under varying conditions.
Water quality monitoring will be carried out using a multiparameter probe at both the inlet and outlet of the bioretention area. This will allow comparison of the physicochemical properties of the water before and after treatment, providing insight into the system's treatment performance and its ability to improve water quality.
Biodiversity monitoring will focus on assessing the area's ecological value through the quantification of bird species abundance within the SUDS site.
