Plant/Process Description:
The Metropolitan Syracuse Wastewater Treatment
Plant (Metro) provides high quality treatment for
270,000 people and many industrial and commercial
customers in the City of Syracuse and some areas
of Onondaga County. Metro treats an average of 84
million gallons per day. Full secondary and
tertiary treatment can be provided for up to 126
million gallons per day. Metro has a total
hydraulic capacity of 240 million gallons per day
during wet-weather events such as rain
storms.
Wastewater treated by Metro
Wastewater reaches Metro from a number of
sources. The largest is the Main Interceptor
Sewer (MIS) that runs north-south through nearly
the center of Syracuse. The MIS is 90-inch in
diameter.
The Harbor Brook Pump Station contributes 30
million gallons per day (MGD) to Metro. In
addition, the Ley Creek, Westside, and Liverpool
pump stations convey wastewater to Metro.
This influent enters a diversion structure that
can channel wastewater to either of the two grit-
removal facilities at Metro. An overflow
structure prevents any flooding at the treatment
plant in case of an emergency.
Preliminary treatment
The first step in treating the sewage at Metro is
the removal of sizable objects. The wastewater
flows through large racks with spaced steel bars,
and debris that cannot fit through the spaces is
caught on the racks. This material is removed and
disposed of.
The wastewater next enters the grit chambers.
Sand, stones, and other small bits of solid waste
are removed there. Wastewater then flows through
screens where additional debris is
removed.
Influent pumping
Since water always flows downhill naturally, it
is easier to manage the wastewater if it flows by
gravity through Metro. The low-lift pump station
raises the incoming wastewater to such a level.
The station has five centrifugal pumps rated for
600 horsepower. The pumps' speeds vary depending
on the amount of wastewater entering the plant.
Each pump has the capacity to handle 60 MGD—for a
total of 240 MGD for the low lift pump
station.
The wastewater is discharged from the lift
station to a 90-inch diameter force main that is
820 feet long. At an average rate of 84 MGD, the
flow is 2.2 ft/sec.
