The Great Lakes Water Authority (GLWA) is requesting a design-build contractor to make access improvements and furnish cleaning, debris removal and disposal services for at the Baby Creek Combined Sewer Overflow Screening & Disinfection Facility (CSO Facility) and provide condition assessment and repair of the flow meters located in the sewers sited on grounds common to the Woodmere Pump Station located within Patton Park, northeast of the intersection of Dix Avenue and Vernor Highway in Detroit, Michigan. Debris carried by combined storm sewers have accumulated within the concrete influent channel (Forebay Conduit) to the CSO Facility and in dry weather flow chambers passing beneath a portion of the CSO Facility’s Screening Building. The limits for removal of the debris in the Forebay Conduit is encompassed by the Baby Creek, Elmer Ternes, and Woodmere Pump Station discharge sewer stop log locations, as shown on Figure 1 – Site Plan (Exhibit A). The depth of debris within the project limits has been estimated to be up to 7-feet in certain locations, this depth is primarily upstream of the influent high weir overflow wall adjacent to the influent channel. The distribution and depth of the debris varies throughout the Forebay Conduit and in dry weather flow chambers (channels) passing beneath a portion of the Screening Building and extending through the treatment sewer.
