Whereas, provision of safe drinking water supply is an effective health intervention reduces the mortality caused by water-borne diseases by an average 70 percent. Inadequate drinking water not only resulted in more sickness and deaths, but also augments health costs, lower worker productivity and school enrolment [World Bank (1994)].
