The definition of sewage (waste water) is both grey water which is water used in private houses from toilets, dishwashers, sinks, baths and showers and black water which is any water from toilets. This foul water can be treated by using either biological matter to break down the waste or physical treatment using aeration to treat the water.
Wastewater treatment, also known as sewage treatment, is the process of removing contaminants and suspended solids from primarily household waste such as toilets, showers and sinks but also from commercial properties such as office spaces and factories and producing treated water to go back into a water course such as a stream or river.
If you are not connected to the main sewer network, then you will need to install some form of sewage treatment system to process the waste water into a form that can be safely drained into your local water course or can be discharge into a soakaway.
