What is the difference between sewage and sewerage?

Although it may not be the first topic of conversation at a dinner party, wastewater, sewage, and sewerage are crucially important features to any city waste system. Wastewater is any water that has been tainted by human use, including industrial, commercial and domestic use, and must be treated appropriately to ensure the best outcome for the environment. And, when talking all things wastewater, the terms ‘sewage’ and ‘sewerage’ usually pop up along the way.

Contrary to popular belief, sewage and sewerage are actually two different concepts which coordinate together to form a major part of waste systems in every major city across the world. They make up the waste and the structures that leave your home and workplace and flow to a treatment plant… so they are so much more important than you know.
