SAN-1233EV-RD-PP-CONT3-SHT3OF17.TIF

The file SAN-1233EV-RD-PP-CONT3-SHT3OF17.TIF is a project document for the Walnut Lake No. 2 Conveyance CAP Phase II, involving the Detroit Water and Sewerage Department (DWSD) and the Great Lakes Water Authority (GLWA) in Michigan. The project scope includes complex sewer infrastructure modifications, specifically the removal and replacement of existing 78-inch and 66-inch diameter sewer siphon pipes, with comprehensive infrastructure upgrades. Key project components include constructing temporary bypass conduits, slip lining and grouting existing siphons with a 54-inch pipe, modifying junction and meter chambers, constructing new sanitary sewer sections ranging from 66-inch to 96-inch diameters, and abandoning multiple existing sewer lines along the M-39 Southfield Freeway and M-102 West Eight Mile Road.

The project involves significant civil engineering work with substantial infrastructure investments, including procurement and installation of a new 96-inch sluice gate with electrical connections, structural concrete work, asphalt paving, grading, and landscaping. While specific budget details are not provided in the document, the project appears to be a major municipal infrastructure renewal effort requiring specialized engineering and construction expertise. The complexity of the project suggests significant technical challenges, including hand mining over existing siphons, flow control management, and intricate underground utility modifications in a densely developed urban corridor.
