Water Reuse and Reclamation Management
Summary
Water reuse and reclamation management encompasses the collection, treatment and redistribution of municipal, industrial and agricultural wastewater to reduce freshwater demand and enhance sustainability. Drivers include chronic water scarcity, urbanisation, climate change and the pursuit of a circular economy. Advanced treatment technologies—such as membrane filtration, advanced oxidation processes and ultraviolet disinfection—enable production of water suited to a spectrum of applications, from irrigation and industrial cooling to indirect potable reuse. Integrated management combines technical design with regulatory frameworks, economic incentives and public engagement to ensure health protection, environmental stewardship and cost-effectiveness. Decentralised treatment systems and resource recovery units can alleviate infrastructure pressures in rapidly growing urban areas and in low- and middle-income countries, where informal irrigation practices predominate. Governance arrangements must bridge gaps in standards, monitoring and risk assessment, while fostering stakeholder trust and addressing social acceptance. Practical applications range from greywater recycling in buildings—improving construction water efficiency and concrete performance—to large-scale reclaimed water schemes augmenting river flows and replenishing aquifers. Effective programmes demonstrate how policy alignment, investment in treatment capacity and adaptive management can deliver reliable water supplies, mitigate pollution and contribute to sustainable development goals worldwide.

About these summaries
This Nature Research Intelligence Topic summary is created with the cited references and a large language model. We take care to ground generated text with facts, and have systems in place to gain human feedback on the overall quality of the process in line with our AI principles. We strive to create accurate and useful summaries for people unfamiliar with the research topic and that supports this goal. These pages are a beta release and will be updated as we learn how best to help people gain value from a research topic summary.
