The Italian Integrated Water Service as a Promoter of Soil Desealing Processes

Abstract

Urban soil sealing exacerbates climate change impacts by disrupting the hydrological cycle and increasing flood risks. This paper examines how Italian Integrated Water Service Companies are promoting soil desealing to enhance urban resilience and environmental sustainability. Case studies of MM S.p.A., Gruppo CAP, and BrianzAcque in Lombardy reveal a strategic shift towards implementing Nature-based Solutions and Sustainable Urban Drainage Systems, such as depaving and bioretention areas. Regional policies, like Lombardy’s hydraulic invariance principle, and national funding are crucial enablers. While promising, the limited geographical spread of these initiatives underscores the need for broader national adoption and supportive policy frameworks.
