This article presents a comprehensive analysis of modern water-saving technologies and their integration into the development of the green economy. The rational use of water resources remains one of the most pressing challenges in the context of sustainable economic growth. Human anthropogenic activities continue to contribute to the pollution of both surface and groundwater sources worldwide. Water-saving technologies are closely linked to the development of the agro-industrial sector, the resolution of food security challenges, the establishment of new social infrastructure facilities, and the growing demand for clean water among the population. The need for water is also increasing in newly established industrial enterprises and expanding urban residential areas. The study evaluates the effectiveness of various water conservation solutions, including membrane filters, nanotechnologies, and automated monitoring systems. Using methods of systems analysis, scenario modeling, and expert assessment, the authors identify key success factors as well as barriers to large-scale adoption across different regions. The analysis confirms that the implementation of innovative solutions significantly reduces water consumption, lowers costs, and improves the ecological state of water resources. Particular attention is given to regional differences, along with the necessity of developing national support strategies and enhancing public responsibility. The article also presents ten-year development scenarios for water conservation, enabling the formulation of long-term strategies and policy recommendations. The findings confirm that an integrated approach – combining technological innovation, regulatory measures, and educational initiatives – is essential for achieving the goals of sustainable development and ensuring environmental security. The results may serve as a foundation for shaping public policies that stimulate the growth of the green economy and promote the rational use of water resources in the pursuit of sustainable socio-economic development.
