The circular water economy reimagines water as a renewable, regenerative resource— one that can be continuously recovered, reused, and reintegrated to create value across communities, industries, and ecosystems. This book provides a comprehensive exploration of this transformative approach, centered on three core strategies: Reduce, Recover, and Regenerate. Readers will gain a clear understanding and definition of each core strategy, along with practical insights into their financial benefits, supporting technologies, and implementation frameworks. The book also highlights the importance of public outreach and stakeholder engagement in driving successful adoption. Through real-world case studies, this resource demonstrates how circular water principles can be applied across diverse settings, offering actionable guidance for utilities, policymakers, engineers, and sustainability professionals seeking to build more resilient and efficient water systems.
