operation & maintenance:

Onondaga County's Department of Water Environment Protection (WEP) is responsible for the operation and maintenance of:
  • 6 wastewater treatment plants
  • 150 pump stations
  • 3 regional treatment facilities
  • 5 floatables control facilities
  • 4 drainage districts
  • various regulatory programs associated with those facilities

green house gas emmissions:

Of the 6 wastewater treatment plants, Metro is the largest plant and serves as a processing facility. Sludge from the applicable treatment plants is transported via hauler to Metro's sludge blending tank and then sent on for anaerobic digestion, a process by which pathogens within the sludge are destroyed. Once it is routed to a secondary digester/gas holder it is sent on to be processed. A direct byproduct of the digestion process is the production of biogas - largely consisting of methane. The methane is then used to operate several on-site boilers, which in turn supplies heat to Metro campus buildings, and is also used for heating via heat exchanger the sludge being processed in the aforementioned digesters (the anaerobic digestion process needs to be operated at approximately 95 - 100 degrees Fahrenheit). The majority of methane produced from the previously described digestion process is used as make-up gas for on-site boilers. Currently, any gas not used at the Metro treatment plant is flared (burned) so as to minimize green house gas emissions.
