With the continual increment in population and severe droughts, we are facing receding water levels in urban areas. Where The water demands have only gone up, Rainwater harvesting is becoming a more important aspect of the toolset for long-term water management. Hence we have chosen an IoT-based approach to solve the issue which was missing in this particular field even though there have been some microcontroller-based approaches. With the installation of a reservoir and a few sensors, this proposal will ensure better water management for the urban areas, whether in the presence or absence of a power supply. This solves many preexisting problems like overfilling of the reservoirs as the monitoring is done at all times. As samples of our Approach-Water of all qualities, clear, opaque, and dirty were tested- and it was possible to distinguish successfully.
