The government file SAN-1600EV-CP-PP-SHT1327.TIF relates to a complex sanitary sewer infrastructure project involving Detroit Water and Sewerage Department (DWSD) and Great Lakes Water Authority (GLWA) in Michigan. The project encompasses comprehensive sewer system modifications, including removal and replacement of existing 78-inch and 66-inch diameter siphon pipe connections, construction of new sewer tunnels and pipelines, and infrastructure upgrades. Specific project components include establishing temporary flow bypass conduits, slip lining and grouting existing siphons, modifying junction and meter chambers, constructing new sanitary sewers ranging from 21-inch to 96-inch diameters, abandoning multiple existing sewer lines, and installing a new 96-inch sluice gate with electrical connections.

The project involves significant civil engineering and infrastructure improvements with multiple technical specifications, including structural, electrical, and telemetry components. The work will occur along the M-39 Southfield Freeway and involves complex tunneling and sewer line replacement strategies. While specific budget details are not provided, the project represents a substantial municipal infrastructure investment focused on upgrading and modernizing critical wastewater conveyance systems. The technical complexity suggests this is a high-value capital improvement project requiring specialized engineering and construction expertise in municipal infrastructure rehabilitation and expansion.
