An Automated Water Level Control System to Prevent Tank Overflow and Water Wastage

Water scarcity and inefficient water management have become pressing global issues in the 21st century, exacerbated by rapid urbanization, climate change, and aging infrastructure. In many communities, significant volumes of water are lost due to tank overflow and poor monitoring practices, contributing to unnecessary water consumption and increased utility costs. This study proposes the design and implementation of an Automated Water Level Control System that uses sensors, microcontrollers, and real-time monitoring to maintain optimal water levels in storage tanks. The system detects the water level in tanks and automatically controls the inflow to prevent overflow, thereby minimizing water wastage and reducing manual intervention. Field testing in residential and institutional settings showed a notable reduction in water overflow incidents and improved water use efficiency compared to traditional float valve systems. By integrating Internet of Things (IoT) features, stakeholders can remotely monitor water levels and receive alerts, making the system adaptive to diverse water management scenarios. The results highlight the potential of automation in enhancing sustainable water practices, which is essential given today’s challenges in water conservation, resource optimization, and environmental stewardship. This system offers a viable solution for municipalities, homeowners, and industries aiming to conserve water and mitigate the impacts of water scarcity.
