Smart technology always has the potential to contribute to solving problems faced by society or globally, and this approach should continue. Smart water meters are one such technology with the potential to track water consumption and identify ways to improve the system for better water sustainability in the future. Water scarcity is a pressing global issue, and the hospitality industry plays a significant role in water consumption. This chapter will demonstrate how smart meter technology is crucial for water-saving technologies in hotels and restaurants, with Smart Water Metering as a critical tool for ensuring sustainability. Traditional water meters or manual records systems may have limitations, but smart meters provide real-time data on water usage. This chapter will explore how these techniques empower hotels and restaurants to: Track Consumption Patterns and Identify Improvement Areas, based on understanding of water usage across different areas of the establishment, pinpointing areas with high consumption. The hospitality industry can significantly reduce its water footprint and contribute to national and global water conservation efforts. Additionally, the chapter will highlight the benefits of smart metering, including cost reduction, enhanced sustainability, and a positive public image.
