Next generation decentralized water systems: a water-energy-infrastructure-human nexus (WEIHN) approach

Abstract

The escalating challenge of water scarcity, intensified by water-energy interdependency, demands an urgent shift towards sustainable solutions. As this concern heightens, the focus on water-energy-infrastructure-human nexus (WEIHN) becomes pivotal to achieving sustainable and resilient water management strategies. In the context of rapid urbanization and population growth, decentralized water systems (DWS) have emerged as a promising alternative to centralized water systems (CWS), offering cost-effective and environmentally sustainable solutions tailored to local water needs and demands. However, a comprehensive and integrative analysis of the economic, social, and environmental impacts needs to be considered before the implementation of DWS in WEIHN. Therefore, analyzing WEIHN at a cross-sectoral level and exploring the roles of infrastructure and humans can provide valuable insights into the challenges and opportunities associated with DWS development. This review provides a forward-looking roadmap that highlights the critical roles of the infrastructure and human perspectives in WEIHN. First, we identify roadblocks in the CWS and then point out the targeted areas supporting DWS. Second, we investigate the current capability and limitation of infrastructure spatial configuration, safety-related metrics, and interdependency in WEIHN. Third, we emphasize the significance of various human roles, including end-users, operators, and decision-makers in WEIHN. Finally, based on the review findings in water, energy, infrastructure, and human dimensions, we conduct a comprehensive in-depth analysis of innovative technologies (e.g., sensor fusion, digital water infrastructure) and effective management policies.
