How does sewage travel from your home to a sewage plant?

Sewage travels from your home by pipes. The flow is due to the slope of the pipes so the sewage is essentially flowing downhill to a collection well or pit.

The collected sewage is pumped from the pits into a forcemain which pressures the material to a sewage treatment plant.

In rural ares or industrial parks sewage sometimes flows to a collection tank which is pumped out and into a truck which carries it to sewage plant for discharge to the treatment system
