Interpretations and Explanations

Proper disposal of the effluent or liquid wastes of latrines is important for human health. Some of the demands for water, particularly for agriculture and fish breeding, can be met by reusing properly treated effluent, since the water quality requirements for these purposes are not as high as for drinking-water. Both industrial effluent and domestic sewage should be treated to minimize pollution risks. The treated wastes should not contain pathogens, because these could contaminate products and infect consumers, or be accidentally ingested by farmers during handling. When wastewater is reused, care should be taken to separate domestic effluent from industrial effluent, since the industrial effluent may contain chemicals harmful to health or the environment, such as heavy metals.
