“…Therefore, this study focuses on specific ways to examine the possible strategies to incorporate sustainable solutions, particularly in urban areas, for increasing the value of water in identified major water-demanding components. Even though some previous relevant studies have been conducted [1,2,6,9,10], this study has the novel concept of including all the components in a study. Urban water services must exhibit resilience and sustainability to alleviate water scarcity in urban areas.…”

“…Urban water services must exhibit resilience and sustainability to alleviate water scarcity in urban areas. The sustainability of services encompasses not only the tangible infrastructure but also the approach to the execution and administration of the systems [9], in addition to the enabling environment for the sector and other overarching considerations, such as the evaluation of water resources. One potential approach to addressing the issue of water scarcity is the emerging concept of incorporating water valuation within urban areas as a sustainable solution over time.…”

This study examines water scarcity and quality deterioration in various components of the urban setting, including agriculture, manufacturing, construction, residential buildings, and the recreational industries. This paper also analyzes various measures that can be used as valuation matrices to assess the quality and quantity of water consumption, as well as conservation practices and sustainable management strategies. The aim of this work is to enhance and encourage an increase in the value of consumed water through economistic, efficient, and sustainable approaches. The analysis includes the evaluation of measures such as price reform, adoption of efficient appliances, implementation of effective utilization techniques, reduction in water waste, treatment of wastewater, and employment of reuse and reclamation techniques. This article further discusses the multifaceted costs associated with the acquisition of water, emphasizing the need to consider not only economic factors but also environmental and social implications. This study examines the potential adverse effects of introducing value-added measures, specifically focusing on the impact of water pricing reforms on farmers and industrial manufacturers. The analysis highlights the potential increase in costs that these stakeholders may face as a result of such reforms. This study suggests that the implementation of subsidies can be an effective measure to mitigate the negative effects discussed. This article highlights the urgent global need for governments and international organizations to implement strict policies and regulations in order to preserve water resources and protect their inherent value and, also, emphasizes the importance of consumers understanding the true value of water in order to grasp its significance and scarcity.

The water supply and sewage sector (WSS) is essential for promoting health and providing the population with drinking water and the adequate disposal of effluents. Assessing the evolution of performance in WSS allows for highlighting the best and worst results achieved, identifying benchmarks, and pinpointing sources of improvement for water services. Brazil has a large population and immense freshwater reserves that are unevenly distributed throughout the territory. This situation emanates a challenge that requires the efficient management of water resources. This study develops a composite indicator framework based on the robust Benefit-of-the-Doubt (BoD) approach to estimate the performance of municipalities of the Brazilian State of Santa Catarina from 2009 to 2021, considering financial, operational, and quality dimensions associated with the provision of WSS services. Subsequently, the Global Malmquist Index (GMI) is applied to assess the performance evolution of the municipalities over time. The BoD results enable the quantification of the relative contribution of each sub-indicator to the performance score, allowing the assessment of the strengths and weaknesses of each municipality. The GMI results show an average performance loss of 3.3% in Santa Catarina state and considerable variability among municipalities, with scores ranging from losses of 54.2% to gains of 109.3% in the period analysed.
