domestic and biological waste effluent that are disposed of via the water drainage system.
sewage
Sewage includes domestic, municipal, or industrial liquid waste products disposed of via a pipe or similar structure. The physical infrastructure, including pipes, pumps, screens, channels etc. used to convey sewage from its origin to the point of eventual treatment or disposal is termed sewerage, a term often mistakenly used to refer to sewage.
Composition of sewage
Sewage is a variable liquid mixture comprising material from some or all of the following sources:
Human waste (faeces, paper, wipes and urine + other bodily fluids) also known as black water
Washing water (personal, clothes, floors etc.) also known as grey water
Rainfall collected on roofs, yards, hard-standing etc. (traces of oils and fuel but generally clean)
Ground water infiltrated into sewage pipes
Surplus manufactured liquids from domestic sources ( drinks, cooking oil, pesticides, lubricating oil, paint, cleaning liquids etc.)
General urban rainfall run-off from roads, car-parks, roofs, side-walks or pavements (contains oils, animal faeces, litter, fuel residues, rubber residues, metals from vehicle exhausts etc)
Industrial cooling waters
Industrial process waters
Sea water ingress
Direct ingress of river water
Direct ingress of man-made liquids (illegal disposal of pesticides, used oils etc.)
The composition of each sewage stream varies widely, but sewage derived from a large city can be expected to contain (the examples given here represent only a small proportion of the range of materials actually encountered):
Water ( > 95%) and is often added during flushing as a means to carry the waste down a gravity line
Non pathogenic bacteria (> 100,000 / ml)
Pathogens - (Bacteria, viruses, prions, parasitic worms).
Organic particles (Faeces, hair, food, vomitus, paper fibres, plant material, humus etc.)
Soluble organic material (Urea, fruit sugars, soluble proteins, drugs, pharmaceuticals etc.)
Inorganic particles ( sand, grit, metal particles, ceramics etc)
Soluble inorganic material (ammonia, road-salt, sea-salt, cyanide, hydrogen sulphide, thiocyanates, thiosulphates)
Animals (Protozoa, insects, arthropods, small fish, etc.)
Macro-solids (sanitary towels, nappies/ diapers, condoms, needles, children's toys, body parts, etc.)
Gases (hydrogen sulphide, carbon dioxide, methane)
Emulsions ( oils in emulsion, paints, adhesives, mayonnaise, hair colourants)
Toxins (pesticides, poisons, herbicides )
Sewage disposal
(See also sewage treatment)
In some urban areas, sewage is carried separately in sanitary sewers while runoff from streets is carried in storm drains. Access to either of these is typically through a manhole.
Sewage may drain directly into major watersheds with minimal or no treatment. When untreated, sewage can have serious impacts on the quality of an environment and on the health of people. Pathogens can cause a variety of illnesses. Some chemicals pose risks even at very low concentrations and can remain a threat for long periods of time because of bioaccumulation in animal or human tissue.

Sewage originates in our homes and industries. Domestic sewage consists of everything that goes down the plughole in the kitchen, bathroom, toilet and laundry.
It also includes the 'gully' trap, but should not include run-off from roofs, streets, driveways, etc. which flow into the stormwater or drainage system.
On average, three quarters of the water supplied to domestic customers and most of the water supplied to industrial customers ends up being collected by the sewerage system.
Naturally, this proportion varies from summer to winter and depends on whether you live in a flat or a house with a large garden.
Around 93% of the sewage collected is transferred to Melbourne Water for treatment at either the Western or Eastern Treatment Plants

sewage is waste weather human IE toilet or weather it be chemical, sewage goes to a sewage plant mainly through sewage pipes under ground to be filtered a couple of times and cleaned, then processed. And believe it or not recycled into water and other.Hope this helps.

Sewage is any water that is used and has to be piped away from your house, office or school. Most people think of sewage as the water you flush down the toilet, but it is also bath and dishwater.
