Chu
& Gassman has and continues to provide electrical
design, construction sequencing, construction
management, inspection and operational assistance
services to Queens County, Bowery Bay Wastewater
Treatment Facility, located in Queens, New
York. The complete plant upgrade and renovation
has involved multiple phases of construction
with several contracts per phase over a period
of 15 years.
The Bowery Bay project consisted of many phases
of electrical, mechanical and instrumentation
work including but not limited to, the following:
Replacement of entire HVAC systems for existing
facilities and new system for Residuals Building
and Service Building including design of 4-750
hp boilers, pumps, piping, and instrumentation
system. HVAC system included replacement of
40 heating and ventilating units of total
capacity of 750,000 cfm.
The electrical distribution system is to be
extensively modified with the replacement
of a 208 volt system with a modern 480 volt
system. New 5kV switchboard and controls for
the plant's main process air blowers (8 @
1250 hp each) are to be provided. The main
sewage pump controls will be modernized to
utilize adjustable frequency drive (5 @ 800
hp).
Rehabilitation to the Con Edison service substation
will be provided. Old air magnetic 5kV circuit
breakers are to be replaced with modern vacuum
breaker designs.
All electrical equipment will be monitored
from a central control room. New air-conditioned
control rooms will be provided to contain
the plant's electrical equipment in order
to minimize the corrosion attendant to the
plant's proximity to the marine environment.

The
Red Hook Water Pollution Control Plant is
designed to treat an average dry weather wastewater
flow of 60 million gallons per day (mgd) and
a peak wet weather flow of 120 mgd. It is
a conventional, open-air facility, using step
aeration for full Secondary Treatment and
final disinfection to achieve an effluent
quality consistent with regulatory standards
(85% removal of pollutants).
Chu & Gassman provided electrical (including
fire/smoke alarm systems) and HVAC design
services for this project incorporating bio-gas
fired co-generating facilities, a tri-fueled
hot water generating plant. Modern computer
controls were utilized throughout. We also
provided start-up services for main pumps
and blower and main substation equipment and
control panels. |
