Sources of water
The water that OCWA delivers meets or exceeds all
government environmental standards.
Customers of the Onondaga County Water Authority receive water that originates
from Otisco Lake, Lake Ontario, or Skaneateles Lake. Customers located in
certain areas may get a mixture of these waters or their source water may vary
with changes in seasonal demand. For 2007, OCWA supplied approximately 40.368
million gallons per day to its 340,000 residential customers located in
suburban Onondaga County and parts of Madison, Oneida, and Oswego counties.
OCWA also supplies water to eight other Central New York town water systems and
thirty large industrial customers.
OCWA treats and delivers water from Otisco Lake; the easternmost and smallest
of the Finger Lakes. In 2007, approximately 16.722 million gallons per day or
41.2% of OCWA's water came from Otisco Lake. The customers receiving water originating
from Otisco Lake are mostly located in the southern and western half of
Onondaga County.
OCWA buys water wholesale from the Metropolitan Water Board at a number of
different supply connections. MWB treats water originating from Lake Ontario
near the City of Oswego. In 2007, approximately 23.305 million gallons per day
or 57.4% of OCWA's water came from Lake Ontario. The customers receiving water
originating from Lake Ontario are mostly located in the northern and eastern
half of Onondaga County. OCWA customers in Madison, Oneida, and Oswego counties
receive all their water from Lake Ontario.
The City of Syracuse Water Department has the responsibility of treating and
delivering water originating from Skaneateles Lake. In 2007, approximately
0.562 million gallons per day or 1.4% of OCWA`s water came from Skaneateles
Lake water purchased from the City of Syracuse Water Department through various
supply connections. OCWA uses this water to supplement areas close to the city
boundary when needed. OCWA customers living in Nedrow, Southwood, and the area
west of the Village of Camillus, get water from Skaneateles Lake exclusively.
The first step in water treatment is to protect the source. OCWA and the City
of Syracuse have been conducting ongoing watershed inspection, monitoring, and
educational programs for a number of years. These programs are in conjunction
with the State and Onondaga County Departments of Health. OCWA, MWB, and the
City of Syracuse all monitor lake conditions on regular intervals prior to
treatment.
The New York State Department of Health has recently completed a Source Water
Assessment Program (SWAP) in order to better recognize potential sources of
contaminants in every water source used throughout the State.
