Harbor Brook CSO Abatement Project Facility Plan (Aug 2005)
by Brown and Caldwell
for Onondaga County Dept of Water Environment Protection

Harbor Brook CSO Abatement Project Facility Plan (Aug 2005)

Onondaga County entered into an Amended Consent Judgment (ACJ) in 1998 that requires it to eliminate or capture for treatment at least 85% by volume of the combined sewage collected in the combined sewer system during precipitation events, eliminate or minimize floating substances in Onondaga Lake attributed to the County's CSOs, and achieve water quality standards for bacteria for all portions of Onondaga Lake that are Class B.

The ACJ listed the Harbor Brook In-Water System (HB IWS) as an Interim CSO Project. The purpose of this facilities plan is to compare the HB IWS to alternatives for abatement of CSOs in the Harbor Brook basin, including regional facilities and sewer separation. The comparison is based on engineering and operational considerations, environmental and community effects, and cost-effectiveness.
