Sewage
Sewage is made up of water from washbasins, kitchen sinks and baths, the waste flushed down the toilet and rainwater from roads, roofs and gardens.
It is treated at our sewage treatment works before being safely returned to the environment.
Our works also deal with various types of industrial effluent - mainly liquid organic waste from industries such as dairy product manufacturers, abattoirs and food factories.
Almost all sewage is organic which is why sewage treatment works use natural, organic processes.
