Sustainable Water Management in Urban Areas through Smart Water Circulation Systems

Abstract Urbanization is a significant global trend that profoundly impacts water security. By mid-century, a large majority of the global population is expected to reside in urban areas, intensifying challenges related to water scarcity. The International Water Management Institute forecasts that most of the world’s population encounters physical and economic water shortages. In response to these challenges, the potential of recycled water is increasingly being recognized, with global capacity for water reuse projected to rise significantly over the coming years. Implementing smart water circulation systems in urban environments is essential for maintaining water balance and enhancing water use efficiency. This approach involves the integration of diverse recycling technologies with smart water networks, allowing for real-time monitoring and optimization of water resources. Initial applications of these systems in parks and other urban spaces provide valuable opportunities for testing and evaluation. The present study aims to develop a comprehensive concept for smart water circulation systems by analyzing various water treatment technologies, assessing their practical applications in urban settings, and creating frameworks for effective implementation. Through empirical analysis and case studies, this research offers practical insights for policymakers and urban planners to address the pressing challenges of water scarcity, thereby contributing to sustainable water use and improved water security in urban areas.
