This article presents a data-reduced modelling framework that uses urban blocks and synthetic sewer networks generated from open geospatial data to simulate combined sewer overflows without requiring detailed infrastructure datasets, validated against 32 monitored events in a Swiss catchment, demonstrating its potential as a scalable and reproducible approach for early-stage screening and prioritisation of decentralised CSO mitigation strategies.
