Sustainable water reuse for water security
Published on by Dr. Cecilia Tortajada, Professor in Practice, School of Interdisciplinary Studies, University of Glasgow, UK
Water security, the reliable access to sufficient clean water, is a critical global challenge exacerbated by climate change impacts like altered precipitation, droughts, and floods. A key solution lies in water augmentation through non-conventional sources, particularly water reuse. This shift from a linear to a circular water use model views wastewater and stormwater as resources. Water reuse has proven effective in enhancing water security for various uses, including urban water supply, irrigation, industrial applications, and environmental needs, especially in water-scarce regions. Successful implementation requires robust governance frameworks encompassing policies and regulations that ensure safe treatment, quality, and distribution, while also driving strategic planning and investment in areas like risk assessment, infrastructure, and public education.
