Combined sewer overflow
Some areas of Syracuse have sewers that carry both
sanitary sewagefrom homes and businessesand also
stormwater from the streets. During dry weather these
sewers carry all the sanitary sewage to the Metropolitan Syracuse Wastewater Treatment Plant for
During times of heavy rain or melting snow, however,
the amount of water is far greater than the capacity
of the sewers. At these times, the sewers overflow and
discharge the excessa combination of runoff and
sanitary sewageinto Onondaga Creek and Harbor Brook. These
discharges eventually reach Onondaga Lake. This is combined sewer overflow (CSO).
The sewer system was designed to overflow in this way
to prevent sewage from backing up into streets and
WEP's Flow Control Division operates the major
portions of Syracuse's combined sewer system and
regularly inspects and maintains overflow relief
points along Onondaga Creek and Harbor Brook.

This notification complies with New York State’s Sewage Pollution Right to Know Act (A.10585A / S.6268D) and complements Onondaga County’s efforts under the Save the Rain Program to reduce pollution to Onondaga Lake and its tributaries.
