The wastewater process - Southern Water

Wastewater comes from water used in the home, in businesses and factories and from rain falling on roofs or the roads and pavements. All wastewater follows the same route, wherever it comes from. It is guided down drains and into sewers that run under roads. These carry the water, now called sewage, to the waste treatment or sewage works.

Sewage versus Wastewater - What's The Difference?

Wastewater often contains large amounts of the nutrients nitrogen and phosphorus in the form of nitrate and phosphate, which promote plant growth. Organisms only require small amounts of nutrients in biological treatment, so there normally is an excess available in treated wastewater. In severe cases, excessive nutrients in receiving waters cause algae and other plants to grow
