“…For example, the Italian government allocated a substantial portion of funding from post-pandemic plans to water loss management. The funding is the National Recovery and Resilience plan [14] referring to the Next Generation EU funding programme [15]. The expenditure is guided by water loss indicators of the Italian Regulatory Authority for Energy, Networks and Environment, ARERA, recently introduced in a regulatory framework to measure and improve the technical quality [16].…”

Recent regulation initiatives and the ongoing digital transition in the water sector are opening a new era in drinking water infrastructure management boosted by unprecedented funding opportunities from the post-pandemic recovery plans worldwide. These investments are not solely directed at updating equipment or replacing aging pipes, but they are geared towards enhancing the efficiency of such infrastructures. Asset management, with respect to the need of leakage reduction and control in drinking water infrastructure, is a major concern for the utilities since water loss undermines the socio-economic and environmental sustainability also with respect to energy resources. In fact, the level of water loss represents an indicator of the infrastructure’s “health” status, thus assuming importance for asset management. The effectiveness of a water loss performance indicator is a relevant issue because it guides the investment, thereby the quality of the public expenditure. The present effort aims at the detailed and scientific analysis of the effectiveness of the linear and percentage water loss indicator. The linear water loss indicator proves to be effective, because scalable, and it is the basis of novel indicator, named Asset Management Support Indicator, which can drive the quality of the expenditure for water loss reduction.

Every year, extreme rainfall events cause human deaths and economic losses around the world. Risk reduction strategies may involve the implementation of structural measures that are widely extended and financial relevant. Despite the high reliance on these mitigation measures, there might occur instances of overload, i.e. events with intensities exceeding the design value of these structures, that may have catastrophic consequences. In this framework, it is crucial to improve hydraulic works management, thus, we introduce a procedure at rain gauge scale for revising design variables throughout their operational lifespan. This enables us to enhance the assessment of the probability of failure of these works. Finally, we investigate instances where design variables experience overload during the recording period, thus assessing the occurrence of rare yet possible events. To this aim we find the most-suitable probability distribution to describe daily rainfall maxima in Italy. Specifically, we test the performance of four widely used bi-parametrical distributions with different tail behaviour, by analysing an impressive dataset consisting of 2282 rain gauges observations from 1860 to 2022. Our results show that: (1) 78% of the empirical samples exhibits heavy-tail behaviour; (2) when the update procedure is applied, 64% of the samples shows a higher-than-expected probability of failure; (3) at least one case of overload associated to a 100-years return period is recorded in almost all regions. Based on our results, existing hydraulic works designed to safeguard populations and their activities from catastrophic events may face a higher risk of failure than initially expected.

L'Italia ha posto la sua attenzione alla questione abitativa attraverso specifici strumenti tra i quali il Programma Innovativo Nazionale per la Qualità dell'Abitare (PINQuA) confluito come specifica misura del PNRR. Il saggio fornisce una visione generale del Programma rendendo esplicite le metodologie di valuta- zione e progettazione adottate per facilitare la circolazione di informazioni utili ad incrementare le performance relative alla qualità dell'abitare anche in altri contesti.
