One of the objectives of Directive (EU) 2020/2184 is to assess the amount of water leakage in water supply systems (WSS) and to reduce it if it exceeds a certain threshold. The Directive is binding on water supply companies supplying at least 10,000 m3/d or serving at least 50,000 consumers. The problem of water losses due to, among other things, aging infrastructure currently requires appropriate action to be taken by WSS management companies. This paper discusses the problem of water losses in the Visegrad Group countries and the challenges and opportunities associated with it. In order to analyze the problem, a bibliometric analysis of the state of knowledge was performed. The results of the literature review present the current directions of research on this topic in the V4 countries as former communist bloc countries. The strengths and weaknesses identified in the paper can be used to plan water loss reduction by water supply companies, researchers, and legislators.
