INTEGRATED DUAL-SOURCING PRACTICAL FRAMEWORK: COMBINING WASTEWATER REUSE AND DESALINATION IN A TWO-PRONGED APPROACH FOR RESILIENT URBAN WATER SECURITY IN TAIZ, YEMEN.

This study proposes a novel paradigm integrating wastewater reuse and desalination for Taiz's water security in Yemen. This hydrological circuit of multiple stages transforms wastewater streams into value-added products, establishing a robust dual-sourcing matrix that mitigates the linear exploitation of resources. The proposed framework strives to generate 0.8 kWh of electricity with 1 m³ of treated wastewater, supplementing Taiz's energy demands. The design includes a solar-powered reverse osmosis plant in Mocha, a GIS-optimized pipeline, and decentralized DEWATS for greywater reuse in Taiz. The closed-circuit system transforms resources, encouraging redundancy and flexibility. It is also integrating GIS and AI-driven for real-time resilience and efficiency, providing critical, sustainable solutions that reduces dependence upon single sources and contribute toward a replicable framework for conflict-affected regions and water-scarce regions. Our system, as a model for conflict regions, can save Yemen roughly $2.3 million every month in imported energy cost.
