A.
INSTALLATION:
BUILDING CONNECTIONS:
1.
Building connections shall be installed using the same construction and pipe joining
techniques as specified in Section 02085 POLYVINYL CHLORIDE GRAVITY PIPE
AND FITTINGS.
In general, connections shall be carried only to the property line. The end of the pipes
shall be closed with PVC stoppers jointed 1n place to ensure against infiltration into the
sewer line.
In general, the mainline sewer has been designed at depths to accommodate full
basement service for each building to be connected. Building connections must be
installed at the proper depth in every case that full basement service 1s possible for the
building. The CONTRACTOR will be required to excavate, remove, reinstall and
backfill any building connection improperly installed at his own expense. The
CONTRACTOR will demonstrate to the Inspector that all connections are properly
made.
In streets where building sewers must cross water mains, the CONTRACTOR will
install the building sewers at proper depths to maintain the vertical clearance between
the two pipes, as shown in the construction details. Building services shall be installed
beneath water mains.
DROP CONNECTIONS:
1.
When the invert of a pipe entering a manhole is 24 inches or more above the invert of
the lowest pipe leaving the manhole, it shall be connected to the manhole with an
inside drop section.
The drop pipe shall be the same diameter, material, and class as the sewer pipe
entering the manhole, unless otherwise noted in the drawings. The drop connection
shall be constructed as shown on the City of Nashua Standard details.
All connecting hardware shall be stainless steel.
