SOMARAJU GIRIDHAR, VANKA KALYAN KUMAR, KARANAM DILLESWARI, NETULA MOUNIKA, Mrs.S. ANUSHA 03 03 Water scarcity has become a critical global challenge due to rapid population growth and the limitations of traditional delayed monitoring systems This paper presents ThirstWise Core a centralized fullstack MERN MongoDB Express React Nodejs platform designed for realtime water scarcity management through citizendriven data collection The system allows users to submit daily localized reports regarding water availability and household consumption A survivalminimum validation logic ensures reported data aligns with the Government of India standard of 135 Liters Per Capita per Day LPCD while enforcing healthsafety thresholds The platform computes a PopulationWeighted Stress Index to translate individual household data into macrolevel insights Processed data is visualized via an administrative dashboard using dynamic colorcoded indicators Normal Warning and Drought to identify highstress regions Evaluation with simulated data across 15 regions demonstrates 94 stress classification accuracy and 87 faster response time compared to traditional manual survey methods Copyright (c) Journal of Science Engineering Technology and Management Science.
