PART 3 - EXECUTION
3.01 INSTALLATION:
A. 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 in 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 is
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.
B. 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.
2. 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.
3. All connecting hardware shall be stainless steel.
