1. What is a Smart Water System? Architecture and Components
The conventional methods of analyzing the water quality require much time and labor. So there is a need to monitor and protect the water with a real-time water monitoring and management system. Smart water systems use smart components, like sensors, controllers, and data centers, to achieve real-time monitoring, transmission, and control of water systems for decision-makers. It is a more cost-effective and sustainable solution and enables real-time monitoring of hydraulic data, automatic monitoring, and alerts from the Cloud platform in case of events such as water leakage or overuse. Smart water management systems are mainly used to remotely control valves and pumps and can measure pressure, flow, and consumption (Gonçalves et al., 2020; Mohd Ismail et al., 2019; Pacheco et al., 2017). A smart water system can lead to more sustainable water services, reducing financial losses and enabling innovative business models to serve the urban and rural population better (Hellström et al., 2000; Ramos et al., 2020).
The smart technologies have helped in developing efficient methods to solve many serious issues in real-time, such as the cost of deployment, power usage, maintenance, privacy and security, complexity, etc. The Internet of Things (IoT) has received substantial attention in the water management sector for its ability to reduce water wastage through higher energy efficiency, low-cost operation, faster processing, and advanced intelligence (Adedeji et al., 2019; Palermo et al., 2022).

2. The Role of the Internet of Things (IoT) in Smart Water Management
Smart water management in supply systems is essential to optimize the use of water resources and the quality of service. IoT refers to a network of interconnected devices that use wireless sensors to collect and transmit data in real-time (Gonçalves et al., 2020). IoT-based smart water management systems generally consist of a controller, sensors, and an application to display the data. Use of IoT platforms provides easy access for remote monitoring and control (Singh and Ahmed, 2021).

Devices in an IoT system can transfer data without human interaction, thereby making them ideally suitable for real-time water distribution, leakage, and level monitoring. The IoT forms an important part of intelligence, which will take care of consumer utilization, water theft detection, water quality control, fault prediction and fault localization. (Narayanan et al. 2020). A smart water monitoring system based on the internet of things will make users mindful of their water consumption and help them reduce their usage. Simultaneously, the system will alert users to abnormal water usage, thereby reducing water loss. This technology also allows easy measurements of water quality for the presence of various contaminants (Sarraf et al., 2020).

3. Benefits of IoT-Based Smart Water Management Systems
In general, smart water management technology can increase the efficiency and stability of a water delivery system while lowering costs and boosting longevity (Gopinath et al., 2022). The integration of the IoT into water management systems can provide several benefits. The main advantages of adopting an IoT approach for smart water management systems are improving water management infrastructures by increasing their efficiency, reducing energy costs and human intervention; resource conservation, reducing water management costs; process optimization by using sensors and connectivity; and increasing productivity (Robles et al., 2014; Pacheco et al., 2017).
The wireless data transmission allows the consumers to measure their water consumption so they can preserve and reduce the water bill, in some cases above 30% (Ramos et al., 2020). In addition, smart water management contributes to leakage reduction, water quality assurance, improved customer experience, and operational optimization, among other key performance benefits (Mounce et al., 2015; Howell et al., 2017). The two main advantages are discussed more in the following.

3.1. Real-Time Alerts for Timely Action
The IoT-based smart water management system can help detect water leaks in a smart home through real-time alerts by analyzing water levels during different hours of the day (Jan et al. 2021). Whether it is a leak, low temperatures, or other potential issues, you will receive real-time alerts via the app, text messages, or phone calls. These timely notifications enable you to take immediate action and prevent further damage to your home. These smart water leak detectors allow you to check the water condition via smartphones.
One of the key features of smart water systems is their ability to automatically shut off the water supply when a leak is detected. This functionality enables you to halt leaks immediately. Even when you're away from home, you can remotely close the water valve through the smart apps.
