自1990年以来，无法获得安全水源的人数一直保持在约11亿人，其中每年约有220万人死于水源性疾病。在发展中国家，人口增长和移民给现有的水和卫生基础设施带来压力，使新基础设施的规划和建设复杂化。为所有人提供安全的水是一个长期目标；然而，仅仅依靠耗时和资源密集型的集中解决方案，如自来水和经处理的水，将使数亿人在遥远的未来得不到安全的水，自给自足的分散的饮用水安全方法，包括使用点化学和太阳能消毒、安全水储存和行为改变，已经经过广泛的实地测试。这些备选方案针对的是受影响最大的群体，可增进健康，有助于发展和提高生产力，值得更优先地迅速实施。
Since 1990, the number of people without access to safe water sources has remained constant at approximately 1.1 billion, of whom approximately 2.2 million die of waterborne disease each year. In developing countries, population growth and migrations strain existing water and sanitary infrastructure and complicate planning and construction of new infrastructure.Providing safe water for all is a long-term goal; however, relying only on time- and resource-intensive centralized solutions such as piped, treated water will leave hundreds of millions of people without safe water far into the future, Self-sustaining, decentralized approaches to making drinking water safe, including point-of-use chemical and solar disinfection, safe water storage, and behavioral change, have been widely field-tested. These options target the most affected, enhance health, contribute to development and productivity, and merit far greater priority for rapid implementation.
