Climate change increases the frequency of extreme rainfall, straining urban infrastructures, especially Combined Sewer Systems (CSS).
Machine Learning (ML) offers cost-efficient alternatives to traditional physics-based models for urban wastewater management.
Neural Network architectures are evaluated for CSS time series forecasting, considering predictive performance, model complexity, and resilience to perturbations.
Local models provide sufficient resilience in decentralized scenarios, ensuring robust modeling of urban infrastructure for sustainable wastewater management.
