Lagos State has grown from 300,000 and 500,000 in 1950 and 1991 to an unprecedented population of 15.7 million (Mabogunje, 2002). Already, it is projected to have a population of 25 million by 2015 which will make Lagos the third largest megacity after Tokyo and Bombay and a population of 29 million by 2020, with an annual growth rate of 8 %( UNCHS, 1996; George, 20R0; LWC, 2011). This scenario presents enormous emerging challenges as well as opportunities that are numerous, diverse and inevitable. This geometric population growth, coupled with accelerated industrialization and urbanization, has contributed immensely to the hydra-headed problems of water scarcity, uneven and inadequate pipe-borne water distribution and transmission, increased exposure to incidence of water-borne diseases such as typhoid and cholera leading to loss of lives and valuable man-hours. There is increased reliability on unwholesome water sources such as "pure" water sachets, polluted surface and underground waters, and increased urban poverty owing to a combination of the above problems, the increased cost of production for industries and increased distribution losses (Akunyili, 2003).
