Sustainable water management in buildings is a critical issue in Gauteng Province. due to the country's water scarcity challenges and the need to alleviate pressure on water resources. This study focuses on investigating water conservation strategies specifically tailored to the Gauteng Province. The research aims to identify and evaluate effective approaches and technologies that can be implemented in buildings to promote sustainable water use and mitigate water waste. A mixed-methods research design is employed. Data on water consumption patterns, conservation measures, and building characteristics are collected through surveys and interviews conducted with building occupants, facility managers, and water utility providers across various regions of Gauteng Province. Water flow measurements and monitoring systems are utilized to capture real-time information on water usage in selected buildings. The study findings reveal that implementing water-efficient fixtures, such as low-flow toilets and faucets, can significantly reduce water consumption without compromising user comfort. Rainwater harvesting systems exhibit promise in supplementing non-potable water needs, particularly for irrigation purposes and toilet flushing, thereby reducing reliance on the strained municipal water supply. Greywater recycling systems show potential for recycling water from sinks, showers, and laundry, providing an additional source of water for non-potable uses in a water-stressed environment. Furthermore, the study explores the importance of raising awareness and fostering behavioral change among building occupants through educational campaigns and water conservation programs. By engaging individuals and encouraging responsible water use, substantial water savings can be achieved at the individual and community levels, contributing to sustainable water management in buildings.
