NI-EA OMID CONTRACT NO. 2 (CONTRACT 2A & CONTRACT 2B)
PCI-18 & PCI-19 REHABILITATION


Sealed proposals will be received on January 18, 2023, at 11 A.M. EST at which time they will be opened and read aloud at the Office of the Oakland County Water Resources Commissioner, Building 95 West, One Public Works Drive, Waterford, Michigan 48328-1907 for the NI-EA OMID Contract No. 2 (Contract 2A & Contract 2B) PCI-18 and PCI-19 Rehabilitation Project in Detroit, Wayne County, Michigan.

PROJECT NARRATIVE

The North Interceptor East Arm (NI-EA) extends south from the Northeast Sewage Pump Station (NESPS), about 12 miles to the Great Lakes Water Authority (GLWA) Water Resource Recovery Facility (WRRF) in Southwest Detroit. At its upstream end at the NESPS, the NI-EA receives sanitary sewer flows from the Oakland and Macomb County communities serviced by the Oakland Macomb Interceptor Drain (OMID) Drainage District (OMIDDD) and upstream tributary sewers flowing into the NI-EA from northern portions of the City of Detroit.

The proposed NI-EA OMID Contract No. 2 PCI-18 and PCI-19 Rehabilitation project is located on
Seven Mile Rd. just west of Van Dyke Ave. and extending along Van Dyke Ave. and Gratiot Ave. from
Seven Mile Rd. to just south of Mt. Elliot St. in the City of Detroit. The project comprises construction
of a new flow control structure with flap gate assembly on Seven Mile Rd. over the existing NI-EA adit
sewer, rehabilitation of existing PCI-663 gate structure on the PCI-18 interceptor which includes
removal of an existing bulkhead gate assembly and replacement with a new bulkhead gate and including
internal automated sluice gate, interceptor cleaning, leak sealing, and repairs in the PCI-18 and PCI-19
reaches of the NI-EA. The project also includes lining of a section of the PCI-19 interceptor on Gratiot
Ave. near Meldrum St. and Mt. Elliot St. using multiple lining products as part of a pilot study. These
lined sections will be monitored in the future to evaluate long-term performance of the various liner
products. The construction of the two flow control structures will provide as-needed flow connectivity
between the existing NI-EA PCI-18 Interceptor and the existing Seven Mile Rd. Sewer and offers dry
weather flow management (diversion) during the proposed lining of the PCI-19 interceptor.
