It is referred to as a "force(d) main". You may or may not see,
hear, or smell the pump house, but it will be there.

What is done when a house's sewer line is below the level of the
main sewer line? I didn't think those lines were pressurized,
so how does a house's sewage system work in those conditions?

For instance in my neighborhood half the houses are about 20
feet below my street. In this instace would the city install a
pumping unit for those houses or would they route the sewer line
towards those houses and out? I guess it depends on the
situation, but still, if the waste treatment plant is above your
house (vertically that is) does that mean your sewage is pumped
to that plant or is sewage all gravity fed?

Always wondered about that, I never hear pumps running under the
street and I didn't think lines were pressurized anyway.
