Each house throughout NYC has a different type of sewer connection to the city sewer. If you have a broken sewer pipe or new construction, it is very important to understand what type of connection you have.

3. The most common connection is the
“spur connection”
however; it is possible that your
building plans may call for another
type of connection due to the details
of your location and project.

4. Manhole Connection
This is the least common sewer
connection.
It is usually required for a larger house
sewer or due to the layout of the house
and city sewer.
EX: if the city sewer stops short and did not extend in
front of the house, the city may require the connection at
the DEP manhole

5. Spur Connection
This is the most common type of sewer connection
for a house in NYC.
This type of connection is most cost effective
as it requires less time and labor to connect
than most other types of connections
The spur is shaped very similar to a Y

6. Curb Connection
This is most commonly found when a new city sewer is installed in the roadway.
A curb connection requires minimal work in the
roadway, if any at all.
A curb connection makes a house sewer installation
or repair less labor intensive and less costly.

7. Fold In Sewer Connection
Is needed if the city sewer does not have an existing spur
and the size of the city sewer is smaller than currently used.
The process includes removing several sections of the
city sewer and folding in new sections of pipe
including a “Y” as mentioned above.

8. Drill In Connection
This is used when a new connection is
required into the city sewer and there is
no pre-existing connection to be used.
Completed with a core drill machine
which is used to carefully drill a hole in
the city sewer after the sewer is
encased in concrete.

9. Riser Connection
This is a pipe that sits perpendicular on the city
sewer and is used as a connection for a house sewer
to the city sewer.
Likely to be used when the city sewer is deeper than
13’ below ground level however; this is not case
100% of the time.
Most commonly used when there is a substantial
difference in elevation from the house trap where
the sewer exits the house, to the city sewer leaving
much greater pitch then allowed as per DEP
plumbing code.
Would also be used if there were underground
conditions such as ground water or large amounts of
rock which would make the house sewer connection
more timely, costly and challenging to install.
