Aqua Smartify: Smart Water Monitoring in Smart Cities with Leakage Detection and Automatic Billing

Innovative management solutions for water-scarcity and wastage are urgent global concerns. The present study develops a Smart Water Metering System using IoT, Arduino Microcontrollers, and renewable energy to manage and use water efficiently. The system monitors water quality and flow in real time using flow sensors, pH meters, and turbidity sensors. A model of tariff-based billing that uses the lowest rates for basic consumption and higher rates for excessive use draws customers towards the efficient use of water. The system also includes a cutting-edge leakage detection tool with a holiday mode that suspends the water supply for a limited period. Integration of the solar panel makes it energy sustainable, thus reducing dependence on conventional power. Real-time notifications and updates to users are done via Telegram, which improves user awareness and participation in the conservancy efforts. Testing data indicated that the system could reduce water wastage up to 30% with an assurance of more than 95% accuracy in monitoring. Although costs associated with installation and dependence on the internet have been hurdles, the long-term benefits outweigh them, making this a practical answer for cities and rural areas alike. Future enhancements could include the incorporation of AI for predictive analytics and blockchain-powered billing that enables high-security transactions.
