Rehabilitation Actions in Water Supply Systems: Effects on Biofilm Susceptibility

Biofilm development in water supply systems (WSSs) depends on infrastructure and operational factors, apart from water quality. We have developed a methodology that considers WSSs hydraulic (operation) and physical (design) characteristics to identify areas with different biofilm development trends within a WSS. To achieve this aim we have used meta-analysis and multi-agent system label propagation via discriminant analysis. As a result, we recognise areas with different susceptibility to biofilm development in a given WSS, and observe how modifications in the infrastructure affect the distribution and extent of these areas.
