Why does sewage need to be “treated” anyway?
Sewage contains bacteria, viruses, nutrients, some chemicals, and a small amount of heavy metals. These contaminants must be treated before they reach the groundwater, in order to prevent the spread of disease and environmental contamination. An SSTS can provide a high degree of treatment if the system is properly designed, constructed, and maintained. An SSTS treats sewage by using biological, physical, and chemical processes.
