In urban areas, rainwater infiltration measures with insufficient barrier effects can become groundwater entry paths for biocidal active substances from building products (in particular facades or protective coatings). In order to better assess this risk, the web model FReWaB-PLUS for the simple simulation of water quantities and thus potentially mobilised biocide loads was developed within the framework of the MUTReWa project.

FReWaB-PLUS is very easy to use for city planners and authorities all over Germany.

This website briefly outlines the biocide problem (problems / biocide discharge) and presents two example substances (environmental behaviour). You can start the model itself here: Simulation
