Sewage or sewerage?

Great question — and one that often causes confusion because the words sound so similar!


💩 Sewage

Sewage refers to the actual wastewater — the substance.

It’s the liquid waste from homes, businesses, and industries. It includes:

  • Human waste (toilet water)
  • Greywater (from sinks, showers, washing machines)
  • Possibly stormwater (in combined systems)

🔹 Think: Sewage = what’s flowing in the pipes.


🚰 Sewerage

Sewerage refers to the system of pipes, pumps, and treatment plants — the infrastructure used to transport and treat sewage.

It includes:

  • Sewer pipes
  • Manholes
  • Pump stations
  • Treatment works

🔹 Think: Sewerage = the network that handles the sewage.


🧠 Quick Memory Tip:

Sewage is the goo
Sewerage is the glue (that holds the system together)
