Project
overview |
|
| |
The
City of Cambridge has awarded
a contract to P. Gioioso &
Sons to separate 22 common manholes
and clean 2 other manholes in
the Central Square area. The
locations of these manholes
include Mass Ave (between Clinton
St and Lafayette Square), Clinton
St, Inman St, Essex St, Norfolk
St, Bishop Allen Dr, and Douglass

Why
is this project necessary? |
|
| |
This
work is required by the Massachusetts
Department of Environmental
Protection, in order to improve
water quality in the Charles
River. This project will reduce
incidents of sewage backups
into certain properties and
will improve the quality of
stormwater discharges to the
Charles River. It is part of
a citywide effort to improve
the Cambridge’s drainage
system and water quality in
our local rivers.

|
|
|
What
will be done to fix the problem? |
|
| |
The
contractor will set up a protected
work zone of approximately 20ft
by 50ft when separating each
common manhole. He will then
use large construction vehicles
to dig down approximately 12
ft, to remove the old common
manholes and install new separate
stormwater and sewer manholes.
He will post “No Parking”
signs and may have to take space
in the roadway to operate. Pedestrian
access and access into properties
will be maintained, but may
be restricted in certain ways.
Manhole locations will be temporarily
patched with asphalt after being
separated. As part o a follow
up contract next spring, sidewalks
and streets will be permanently
restored. |
