SAN-1600EV-CP-PP-SHT1320.TIF

The file SAN-1600EV-CP-PP-SHT1320.TIF is a project specification document involving the Detroit Water and Sewerage Department (DWSD) and Great Lakes Water Authority (GLWA) for the Walnut Lake No. 2 Conveyance CAP Phase II project in Michigan. The comprehensive infrastructure project involves extensive sewer system modifications, including removing existing 78-inch and 66-inch diameter sewer siphon pipes, constructing temporary bypass conduits, slip lining and grouting existing pipes, modifying junction and meter chambers, and constructing new sanitary sewer tunnels and connections. Key project elements include installing a new 96-inch sluice gate with electrical connections, abandoning multiple existing sewer lines, and completing structural concrete work, asphalt paving, grading, and landscaping.

The project appears to be a critical infrastructure upgrade focused on improving wastewater conveyance systems in the Detroit metropolitan area, with multiple complex engineering components requiring specialized construction techniques such as hand mining and tunnel construction. While specific budget details are not provided in the document, the project involves significant civil engineering work spanning multiple sewer diameters (21-inch to 96-inch) and requires sophisticated flow management, structural modifications, and integration of electrical and telemetry systems. The work will take place across various locations including the Evergreen-Farmington Sanitary Drain, M-39 Southfield Freeway, and M-102 West Eight Mile Road, suggesting a comprehensive regional infrastructure improvement initiative.
