Water is highly essential element required for the existence and survival of mankind. Though world is blessed with rich source of water, today it is at the junction of water crisis mainly due to poor management of this valuable resource. Thus main drawback of current system is, it does not contain any efficient mechanism for checking water quality, water level, leakage detection and flow of water etc. For example at present water quality is detected by chemical tests or laboratory tests. This is a manual process and time consuming. Thus efficient water management system becomes need of the hour. This paper proposes usage of Internet of Things(IoT) for water quality and flow management. This novel technique also provides mechanism for alerting user for every threshold water levels by using level sensors, pH sensors for checking water quality, finds the leakage in the tank, theft detection using IR sensor, and also gives the smart billing finally the data analysis has done based on the sensor data using machine learning algorithms. The data collected is also processed and stored to cloud using Raspberry Pi. This provides smarter, low powered water management system with higher mobility and efficiency. Finally all these features form a complete package for smart water management using IoT application.
