What is sewage?
Wastewater from your shower, bathtub, washing machine, dishwasher, kitchen sink and toilet is all considered sewage - it isn't just from the toilet. Interestingly, sewage is actually 99.8% water.
A typical 4-person household produces around 400–500 litres of sewage every day.
Liquid waste from business and industry – also known as trade waste – is considered sewage or wastewater as well.
"Sewerage" on the other hand refers to the system of pipes, pumping stations and treatment facilities that collect and treat sewage.
