FA Questions:

What’s the difference between sewage and effluent?

Basically, we’re talking about the size of the solids in the liquid. Effluent is any liquid that has gone down a residential drain. It can contain solids up to ¾” in size. This is normally considered to be water containing soap, laundry discharge, water from sinks, etc. Sewage has also gone down a residential drain but can contain solids up to 2” in diameter.
