The government file SAN-1600EV-CP-SD-SHT1334.TIF involves a water infrastructure project for the Detroit Water and Sewerage Department (DWSD) and Great Lakes Water Authority (GLWA) in Michigan. The Walnut Lake No. 2 Conveyance CAP Phase II project encompasses comprehensive sewer system modifications, including removal and replacement of existing siphon pipes, construction of new sanitary sewer tunnels and connections, and infrastructure upgrades. Key project components include constructing temporary bypass conduits, slip lining existing 66-inch and 78-inch diameter siphons with a 54-inch pipe, modifying junction and meter chambers, and installing new 96-inch diameter sewer tunnels and sluice gates.

The project involves significant infrastructure improvements with multiple technical specifications, including structural, electrical, and telemetry modifications across various sewer segments. The work will occur along the M-39 Southfield Freeway and M-102 West Eight Mile Road, with specific tasks involving abandonment of existing sewer lines, construction of new manholes and connections, and comprehensive site work including concrete installation, asphalt paving, grading, and landscaping. While specific budget details are not provided, the project appears to be a substantial municipal infrastructure investment targeting sewer system reliability and capacity enhancement in the Detroit metropolitan area.
