Sewer Separation Project at CSO Area 061

Sewer Separation CSO061

The CSO 061 Area includes 1.8 acres within a residential neighborhood in the south side of the City of Syracuse.  During large rain events, the combined sewage from the Crehange Street combined sewer can overflow to an existing 12-inch outfall to Onondaga Creek (CSO 061).

The proposed design includes construction of a new storm sewer along Crehange Street to convey tributary stormwater from the Crehange Street properties, as well as two catch basins that are tributary to the Hatch Street combined sewer.  The CSO-061 outfall will be repurposed and utilized for stormwater discharge only. The existing sanitary sewer along Crehange Street will convey sewage only and the Hatch Street combined sewer will have reduced stormwater contributions.

The County evaluated the use of Green Infrastructure for mitigating overflows at CSO-061.  It was concluded that complete separation would be more effective than green infrastructure due to the short conveyance distance, proximity to Onondaga Creek, and the desire to implement a total closure of CSO-061.

Project Update: It is anticipated that construction on the project will begin by the end of summer 2016.
