Downriver Wastewater Treatment Facility - Tunnel System
Between the years of 1996 and 2001, the Downriver tunnel storage and transport system
was constructed. The purpose of the tunnel system was to divert excess wet weather
flow from the interceptor system to the tunnel when the capacity of the existing
interceptor system was exceeded. The tunnel system was constructed with components
consisting of the following:
- Lower tunnel, which extends from the Wyandotte WWTP west along Pennsylvania Road
to Allen Road, then north along Allen and Pelham Roads to Champaign Road at a total
length of approximately 40,220 feet.
- Upper tunnel, which extends along Pelham Road north from the lower tunnel at Champaign
Road approximately 7,200 feet to Avondale.
- Allen Park Tunnel Spur, which extends to the east approximately 8,000 feet from
the drop structure of the Upper Tunnel at Champaign Road.
- Eureka Road Relief Sewer and Relief Sewer Extension, which extends west along Eureka
Road from the connection to the lower tunnel at Allen Road approximately 43,100
feet to Wahrman Road.
- Pelham Basin to Jackson Street Pumping Station Connection, which extends north approximately
2,750 feet from the Pelham Basin under Highway I-94 and along Jackson Avenue and
Weddel Avenue to Hanover Avenue.
