Malaysia has abundant water resources. However, overpopulation, urbanisation, inadequate water management, and climate change contributed to water stress in several states. Water insecurity particularly in household consumption arose from an imbalance between water demand and supply. In this study, household water security was assessed across five key dimensions: pipe bursts, water amount, water pressure, water reliability or resilience, and price. The study aimed to examine the status of these water security dimensions and to estimate households' willingness to pay (WTP) for improvements to strengthen the overall water security framework. A choice experiment approach was employed to estimate WTP for enhancements in each water security parameter. The questionnaire comprised sections on household experiences with water operators, water consumption patterns, choice experiment scenarios with three attribute levels per parameter, and socioeconomic characteristics. The sample consisted of 500 residential consumers. The findings provided valuable insights for developing a comprehensive household water security framework to support the Energy Transition and Water Transformation Ministry's goal of achieving an estimated 180 litres per person per day by 2025, as well as the United Nations Sustainable Development Goal (SDG) 2030 target of ensuring access to clean water and sanitation for all and promoting long-term water security.
