Intermittent water supply (IWS) is a pervasive issue in many countries across South Asia, Latin America, Africa, and the Middle East. Various factors can lead to intermittency, including natural, technical, and financial scarcity, user behaviour, and institutional aspects. Unfortunately, intermittent access to water can negatively impact public health and social equity, and the systems themselves are often considered unsustainable in the long term.

To address this issue, researchers and practitioners have been working to better understand IWS systems and improve their operation, management, and eventual conversion to continuous water supply systems. This special issue presents a collection of high-quality, peer-reviewed technical papers that address the challenges, opportunities, and solutions of IWS systems.

The papers in this special issue cover a range of topics, including:

Authors contribute to highlighting the importance of these topics and providing innovative solutions to the challenges facing IWS systems.

Overall, this special issue is an important contribution to the ongoing efforts to address the challenges of IWS systems, and the papers within it provide valuable insights for researchers and practitioners.
