The introduction of the use of reclaimed water in Windhoek, SWA/Namibia, prompted an epidemiological study to assess the health effects, if any, of its consumption. Analysis of more than 15,000 episodes of diarrhoeal disease during the period August 1976-March 1983 showed that their incidence in whites of similar socio-economic status was marginally lower in persons supplied with reclaimed water than those with water from conventional sources. Incidence rates were significantly higher in blacks and in coloureds, all of whom received conventional water only. Age-specific incidence rates in children of the various ethnic groups also showed differences characteristically associated with socio-economic stratification. It is concluded that the consumption of reclaimed water does not increase the risk of diarrhoeal diseases caused by waterborne infectious agents.
在西南非洲/纳米比亚的温得和克引入再生水的使用后，促使开展了一项流行病学研究，以评估饮用再生水对健康的影响（如有）。对1976年8月至1983年3月期间超过15000例腹泻病病例的分析表明，社会经济地位相似的白人中，饮用再生水者的腹泻发病率略低于饮用传统水源水者。黑人及有色人种的发病率显著更高，他们均仅饮用传统水源水。不同种族儿童的年龄别发病率也呈现出与社会经济分层特征性相关的差异。得出的结论是，饮用再生水不会增加由水传播传染原引起的腹泻病风险。
