The spent water from residences and institutions, (i.e. ablution water, used water from food preparation, laundry,) are classed as domestic or sanitary sewage.

Sewage treatment is physical, chemical and biological processes to remove physical, chemical and biological contaminants. Its objective is to produce treated effluent and a solid sludge suitable for discharge or reuse back into the environment.

Typically, sewage treatment involves three stages called primary, secondary and tertiary treatments. First, the solids are separated from the wastewater stream. Then dissolved biological matter is progressively converted into a solid mass by using indigenous, water-borne bacteria. Finally, the biological solids are neutralized then disposed of or re-used, and the treated water may be disinfected chemically or physically. The final effluent can be discharged into a sea, river or it can be used for restricted irrigation.
