The document is a technical specification file for the Walnut Lake No. 2 Conveyance CAP Phase II project, involving the Detroit Water and Sewerage Department (DWSD) and the Great Lakes Water Authority (GLWA) in Michigan. The project involves comprehensive sewer infrastructure modifications, including the removal of existing 78-inch and 66-inch diameter sewer siphon pipes, construction of new sanitary sewer tunnels and connections, and significant infrastructure upgrades. Specific scope elements include constructing temporary bypass conduits, slip lining and grouting existing siphons, modifying junction and meter chambers, constructing new sewer segments between various connection points, abandoning existing sewer lines, and installing a new 96-inch sluice gate with electrical connections.

The project encompasses substantial civil engineering work along the M-39 Southfield Freeway and surrounding areas, with comprehensive infrastructure replacement and enhancement. While specific budget details are not provided in the file, the project appears to be a complex municipal infrastructure improvement initiative requiring specialized engineering and construction expertise. The work involves intricate underground utility modifications, structural concrete work, asphalt paving, grading, and landscaping, suggesting a comprehensive infrastructure renewal effort for the Detroit metropolitan area's wastewater management system.
