Water for Health - Taking Charge
Foreword
Long before the advent of modern medical care, industrialized countries decreased their levels of water-related disease through good water management. Yet, even in these countries, outbreaks of water-borne disease continue to occur, sometimes with lethal consequences. In developing countries, preventable water-related disease blights the lives of the poor. Diseases resulting from bad hygiene rank among the leading causes of ill-health.
Much of this suffering is needless. Health provides an effective gateway for development and poverty alleviation. Improving water management is a powerful tool that can be used by individuals, communities and households to protect their own health.
