Abstract: The present invention relates to a decentralized greywater recycling system for sustainable water management and reuse of domestic wastewater. The system comprises a raw greywater collection tank, a dual-stage filtration mechanism, a treated water storage tank, sensor-based monitoring units, and an ESP32-based IoT control system. The first-stage filtration unit includes gravel and sand layers for removal of suspended solids and reduction of turbidity. The second-stage filtration unit includes zeolite, gravel, and activated charcoal for adsorption of dissolved contaminants, odours, and chemical impurities. Water quality parameters including pH, turbidity, TDS, and flow rate are continuously monitored using electronic sensors. The ESP32 microcontroller processes sensor data, classifies treated water quality into predefined categories, and displays the information on an LCD module and a wireless web interface for real-time monitoring. The invention provides a low-cost, scalable, and efficient solution for decentralized greywater treatment and reuse in non-potable applications, thereby supporting the development of zero waste water communities.
