Abstract-The intensifying global water shortage demands innovative approaches to sustainable water management. Grey water recycling offers a practical and eco-friendly solution by repurposing wastewater from domestic activities excluding sewage for non-potable uses. This paper presents an in-depth analysis of grey water recycling systems, focusing on their design, implementation, and impact on sustainable water management. We examine the characteristics of grey water generated from residential sources such as showers, baths, sinks, and laundry machines, highlighting the variability in contaminant levels and volumes. Advanced treatment methodologies, including physical filtration, biological treatment with constructed wetlands, and chemical disinfection, are explored to assess their effectiveness in removing impurities and pathogens to meet safety standards for reuse in irrigation, toilet flushing, and industrial processes. The study evaluates the economic viability of grey water systems by analyzing installation costs, maintenance requirements, and potential savings on water bills. Environmental benefits are quantified through reduced freshwater extraction, decreased energy consumption for water treatment, and lowered effluent discharge into ecosystems. We also consider social factors, addressing public perceptions, health concerns, and the necessity for community engagement and education to promote acceptance of grey water reuse. Our findings demonstrate that grey water recycling significantly contributes to sustainable water management by conserving freshwater resources, reducing stress on wastewater infrastructure, and minimizing environmental footprints. We propose a framework for integrating grey water systems into existing urban infrastructures, emphasizing policy recommendations and the importance of supportive legislation to facilitate widespread adoption.
