Singapore is an exemplary model of integrated water management, according to the World Health Organization, and its experiences can be shared with others. Water security is not just the government's responsibility but has become everyone's business. Singapore has been selected as a case study for integrated urban water management (IUWM), and the methodologies used in Singapore, a developed city state, may be applicable elsewhere. An integrated regulatory framework, sound policies to control and implement programmes, public-private partnership in water services delivery, and stakeholder participation at all levels are necessary to make integrated water resource management successful. This paper demonstrates how Singapore has successfully turned its vulnerability with regard to water into a strength. Singapore can achieve greater sustainability if it promotes rooftop rainwater harvesting as a decentralized, dual-mode water supply system for non-potable use.
