Il cambiamento climatico sta aumentando la frequenza di eventi estremi come siccità e inondazioni, minacciando la disponibilità delle risorse idriche e l'efficacia dei sistemi di drenaggio urbano. È quindi essenziale sviluppare piani d'azione sostenibili volti a soddisfare le esigenze locali. L'analisi del bilancio idrogeologico e idrico del bacino ATO1 (Regione Marche) ha evidenziato la necessità di sviluppare diversi scenari di ottimizzazione per la gestione delle risorse idriche urbane. Inoltre, l'analisi del consumo idrico nelle entità del terzo settore, a livello di edificio, occupante e sistema, ha permesso di identificare i fattori chiave per la riduzione dell'impronta idrica attraverso l'applicazione delle migliori pratiche di gestione ambientale (BEMP). Un approccio integrato alla gestione delle risorse idriche, basato sul l'analisi dei rischi, è cruciale per prevenire potenziali problemi. Pertanto, l'elaborazione di piani per la sicurezza idrica (PSA), applicati a vari studi di casi, ha permesso l'identificazione degli eventi più critici. In un contesto di scarsità idrica, il recupero dell'acqua non convenzionale attraverso soluzioni tecnologiche alternative è essenziale per sostenere l'economia circolare. Nel quadro del progetto H2020 HYDROUSA, è stato sviluppato un piano di trasferibilità e replicabilità per valutare l'applicabilità delle soluzioni HYDRO in diversi contesti territoriali. Infine, nell'ottimizzazione dei sistemi di drenaggio urbano, la modellazione delle reti fognarie, calibrata con dati qualitativi e quantitativi in loco, è un passo critico. Un'applicazione in un bacino costiero ha permesso di valutare l'impatto ambientale associato all'attivazione dei Combined Sewer Overflows (CSO). Inoltre, nel progetto HEU WATERUN, è stato sviluppato uno strumento di calcolo per valutare i rischi per la salute umana e l'ambiente associati al riutilizzo/scarico delle acque di scolo, sulla base dell'analisi QMRA e QCRA.

Abstract
Climate change is increasing the frequency of extreme events such as droughts and floods, threatening the availability of water resources and the effectiveness of urban drainage systems. It is therefore essential to develop sustainable action plans aimed at addressing local needs. The analysis of the hydrogeological and water balance of the ATO1 basin (Marche Region) highlighted the need to develop different optimization scenarios for urban water resource management. Additionally, the analysis of water consumption in Third Sector Entities, at the building, occupant, and system level, has enabled the identification of key factors for reducing the water footprint through the application of Best Environmental Management Practices (BEMPs). An integrated approach to water resource management, based on risk analysis, is crucial for preventing potential issues. Therefore, the development of Water Safety Plans (PSA), applied to various case studies, allowed for the identification of the most critical hazardous events. In a context of water scarcity, the recovery of non-conventional water through alternative technological solutions is essential for supporting the circular economy. In the framework of the H2020 HYDROUSA project, a Transferability and Replicability Plan was developed to assess the applicability of HYDRO solutions in different territorial contexts. Finally, in optimizing urban drainage systems, the modeling of sewer networks, calibrated with on-site qualitative and quantitative data, is a critical step. An application in a coastal basin allowed for the evaluation of the environmental impact associated with the activation of Combined Sewer Overflows (CSO). Additionally, in the HEU WATERUN project, a calculation tool was developed to assess human health and environmental risks associated with the reuse/discharge of runoff water, based on QMRA and QCRA analysis.File | Dimensione | Formato | |
