Are you sure they use your street for the main sewer, is there a street
behind their backyard at a lower grade?



It was more of a rhetorical question than anything. My street happens to
be a little higher than the actual main, but like I said other houses in
my neighborhood are well below that level. I'd just never realized that
sewer systems worked on pumps and the like.

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.




Another thing you may not be aware of is that the sewer lines are usually
very deep in most places. Layout of the entire system is done by an engineer
so that it works properly.
