Provision of water for the population is a social responsibility of governments. Managing water resources to meet the target demands of the population requires various demand and supply optimizations. Geographic information systems (GIS) have been embraced to sustainably manage public water supply in most cities of the developed countries. The City of Lagos, which is growing at an annual rate of about 7%, is expected to increase by nearly ten million people between now and 2015. Hence, the task of providing potable water for this teeming population is great. This paper appraises the City of Lagos with its peculiarities, and the state of water provision and population growth. Less than 50% of water demand in Lagos is presently met through public water supply. While potable water production has increased by 61% over the 1977 figure, the population has increased by 320%. The prospects and framework required for managing water problems in Lagos through GIS are also examined.
