A map showing the major sewers in the BSA’s collection is shown on the right. For the purposes of the evaluations conducted as part of the LTCP project, the BSA’s collection system was divided into three Districts based on sewer service areas and the watersheds that drain to these receiving water bodies:
- North (pink highlighted area)
- Scajaquada (yellow highlighted area)
- South Central (green highlighted area)
The North District consists of three main drainage basins: Ontario, Hertel, and Parish. The main interceptor trunk line runs down Hertel Avenue. Six of BSA’s 59 CSOs are located within this District, including the largest CSO in the City (CSO 055) located at Cornelius Creek. Receiving water bodies for the North District are the Niagara River, Black Rock Canal, and Scajaquada Creek.
The Scajaquada District is bounded to the east by the City of Buffalo limits, to the west by the Black Rock Canal, and to the south by West Ferry and Fougeron Streets. The main interceptor trunk line is the Scajaquada Tunnel Interceptor, which extends from the City border with Cheektowaga and discharges to the North Interceptor. Flows from Cheektowaga enter BSA in the Scajaquada District as well. Overflows from the trunk sewers tributary to the Scajaquada Tunnel Interceptor discharge to the Scajaquada Drain, which extends from the City border with Cheektowaga to the Scajaquada Creek at Forest Lawn Cemetery. Eleven of BSA’s 59 CSOs are located within this District. The receiving water bodies for this District are Scajaquada Creek and the Black Rock Canal.
The South Central District is the largest of the three Districts and is bounded by Albany Street to the north, the City line to the east and south, and the Niagara River and Lake Erie to the west. The District can be split into two hydraulically distinct sections by the South Buffalo Pump Station, which pumps flows from the southern portion of the City to the beginning of the South Interceptor. Flows from Erie County Sewer Districts 1 and 4, as well as from West Seneca Sewer Districts 5 and 13 enter BSA’s system in the South Central District. Forty-two of BSA’s 59 CSOs are located within this District. The receiving water bodies are Cazenovia Creek, the Buffalo River, Lake Erie, and the Niagara River.
