Abstract :As urbanisation, population growth, and climate change continue to increase, the availability of water resources is declining. Buildings are places where people spend most of their daily lives and are responsible for a significant portion of the consumption of resources. Water is the leading source of these resources. Therefore, efficient and economical water consumption is substantial. Utilising alternative water sources, such as rainwater and greywater, for applications that do not necessitate potable water quality is a key strategy to help minimise the excessive reliance on main water supplies. Integrated systems where rainwater and greywater are used together in buildings or to complement each other are called \\\"hybrid rainwater-greywater systems\\\". This research aims to conduct a bibliometric analysis of existing literature on hybrid rainwater harvesting-greywater recycling systems within buildings. Scopus and Web of Science databases were used for this purpose. The outcomes were visualised using mapping techniques through VOSviewer software. The results indicate that hybrid rainwater harvesting-greywater recycling systems have not yet garnered adequate attention in research. Therefore, it is evident that hybrid water systems will be the subject of more research in the future. In particular, studies on the development of storage tank design and treatment methods that affect these systems\\\' environmental, social, and economic aspects are expected to contribute significantly to developing the sustainability components of hybrid water systems.
