Methodology for analysis of the SDGs compliance in urban water systems. Implementation in case studies in the Valencian Community

Abstract

[EN] The current economic, social, and technological development demands high quantities of good quality water, putting in more stress water resources. However, if water resources could be managed in a sustainable way, it will be possible to satisfy the present needs without compromising its long-term capacity. Given the situation, it has become a challenge to manage water systems sustainably, achieving all the goals set by the SDGs. In this sense, the sustainability of hydraulic systems must be considered globally to integrate all the aspects that intervenes in the concept, such as the economic, social, technical, and environmental fields. Key performance indicators (KPIs) can help managers to audit and evaluate hydraulic systems over time and from a sustainable point of view. This contribution presents a methodology for the implementation of sustainability indicators that will allow to assess the compliance of all the SDGs goals that intervenes in urban water systems. The defined indicators are linked to the management of hydraulic systems, and it was developed a classification of use based on their usefulness, complexity and cost when measuring them in the systems. This study also proposes a classification by levels of sustainability of the water systems, such as the energy efficiency classification of electrical appliances. The methodology is applicable for all types of hydraulic systems (supply, sanitation, treatment) and for each of its processes (operation, maintenance, administration, infrastructure). For the implementation of the KPIs, the level of development of the country or region where the study is carried out is considered. Therefore, for each case different indicators are defined from those already established to consider the characteristics of the systems and for the calculation of each KPI. A description of the system must be carried out, to have a memory of the evolution of the complete system and to define the indicators that are relevant. Therefore, through the results of the analysis it is possible to establish a benchmarking on the sustainable aspects of the water distribution system would represent a design, diagnosis, and management tool, which will improve sustainability in hydraulic systems. By improving the performance and sustainability of the systems, it is not only possible to achieve the objectives of goal 6, but also other associated goals will benefit, which highlights the relevance of sustainability indicators in hydraulic systems.
