The Map above shows all of the treatment plants and the areas they cover.


The Onondaga County Department of Water Environment Protection (OCDWEP) has a big job to do, operating, maintaining, and protecting the system that collects used water and sewage generated within the Onondaga County Consolidated Sewer District.


Processing over 33 billion gallons of wastewater each year, OCDWEP operates around the clock cleaning the wastewater of homes, businesses and industries before it returns to the environment.


Wastewater is the water that comes from sinks, toilets, and shower drains in homes.


Onondaga County has 2,100 miles of sewers. End to end, it would stretch from Syracuse to Yellowstone National Park! OCDWEP provides service to roughly 346,000 residents, that's nearly 75% of Onondaga County's population!


And according to the EPA, each American uses an average of 82 gallons of water a day at home! To handle all of that wastewater, OCDWEP has six treatment plants, each receiving wastewater from surrounding municipalities.
