Pathogens and Diseases of Sewage Sludge, Septage, and Human Fecal Matter

The collection, disposal, and management of human wastes greatly affect the potential for diseases from pathogens discharged with these wastes (Table 5.1). In developed countries, humans generally discharge fecal matter through toilets into sewage systems or septic systems. The object of the sewer system is to separate the solids from liquids and to disinfect these components before their discharge into the environment. A generalized sewage treatment system is shown in Figure 5.1.
