Water is a fundamental resource essential for human survival and development. It plays a vital role in various sectors, including domestic use, agriculture, and industry. In many institutions, especially educational establishments like Jigawa State Polytechnic, Dutse, the management of water resources is a significant concern. Overhead tanks are commonly employed to store water for various purposes, including sanitation, irrigation, and laboratory use. However, the traditional methods of monitoring and controlling water levels in these tanks often lead to inefficiencies and wastage [1].

Manual operation of water pumps to fill overhead tanks is prone to human error, resulting in either overflow or dry running of pumps. Overflow leads to water wastage, which not only depletes a valuable resource but also causes structural damage to buildings due to seepage and dampness. On the other hand, dry running of pumps can lead to mechanical failure, reducing the lifespan of the equipment and increasing maintenance costs. These issues highlight the need for an automated system that can efficiently monitor and control water levels in overhead tanks [2].

Advancements in technology have paved the way for the development of automated systems that can address these challenges. Wireless communication technologies, coupled with sensors and microcontrollers, offer a promising solution for automating the water level control process. Such systems can provide real-time monitoring, remote control, and alerts, thereby minimizing human intervention and ensuring efficient water management. Implementing such a system at Jigawa State Polytechnic, Dutse, can serve as a model for other institutions facing similar challenges [3].

1.1 Background of the Study

Water is an essential resource for life and development, and its management has become a critical issue in many institutions, especially in developing regions. In educational institutions, water is required for various purposes, including laboratories, hostels, staff offices, and sanitation facilities. Overhead tanks are commonly used to store and supply water to these areas, providing a consistent flow through gravitational force. However, the traditional methods of controlling water levels in these tanks are largely manual, relying on human intervention to switch pumps on and off. This approach is not only labor-intensive but also prone to inefficiency and error, leading to wastage of water and energy [3].

Manual water level control in overhead tanks poses significant operational challenges. When the tank is full, there is often an overflow of water because the pump is not switched off in time. Conversely, if the tank is empty, pumps may continue running without water, leading to dry running, which damages the pump motor and increases maintenance costs. Such inefficiencies can affect the reliability of water supply in the institution, disrupting daily activities and leading to increased expenditure on water management and equipment repair [4].

The integration of automation and wireless communication technologies in water management systems offers a viable solution to these challenges. Automated water level control systems use sensors to detect the water level and microcontrollers to regulate the operation of pumps accordingly. Wireless systems, in particular, eliminate the need for extensive wiring between the control unit and the tank, allowing remote monitoring and control. This reduces human involvement, increases operational efficiency, and ensures that water is used more sustainably [5].

1.2 Statement of the Problem

In many institutions, residential areas, and industrial facilities, the manual operation of overhead water tank pumps has continued to pose significant operational challenges, resulting in both resource inefficiency and equipment damage [6]. Manual monitoring often leads to water overflow, which wastes a vital resource and can cause structural damage to surrounding areas due to seepage and dampness. Conversely, pumps frequently run dry when water levels are not properly observed, leading to overheating, mechanical failure, and increased maintenance costs. The reliance on human intervention makes these systems labor-intensive, inconsistent, and prone to error, reducing the reliability of water supply for critical activities. Additionally, uncontrolled pumping contributes to higher electricity consumption, further escalating operational costs and environmental impact. Inefficient water management in such systems not only wastes resources but also hinders the sustainable utilization of water, which is particularly critical in regions facing water scarcity. These persistent challenges underscore the urgent need for a wireless automated water level control system that can accurately detect water levels, regulate pump operation in real time, prevent wastage, and extend the lifespan of pumping equipment, while reducing human effort and promoting sustainable water use [7].
