SAN-1233EV-RD-PP-CONT3-SHT17OF17.TIF

The file SAN-1233EV-RD-PP-CONT3-SHT17OF17.TIF is a project document for the Walnut Lake No. 2 Conveyance CAP Phase II infrastructure project involving Detroit Water and Sewerage Department (DWSD) and Great Lakes Water Authority (GLWA) in Michigan. The comprehensive sewer infrastructure project includes multiple critical components: removal and replacement of existing 78-inch and 66-inch diameter sewer siphon pipes, construction of temporary flow bypass conduits, slip lining and grouting existing siphons with a 54-inch pipe, modifications to existing junction and meter chambers, and constructing new sanitary sewer tunnels and connections. The project scope encompasses structural, electrical, and telemetry modifications, with specific work including new sewer sections between designated manholes, tunnel construction, abandonment of existing sewer lines, and installation of a new 96-inch sluice gate with electrical connections.

The project involves complex infrastructure upgrades along the M-39 Southfield Freeway and surrounding areas, with significant engineering and construction requirements. While specific pricing, funding sources, and contract terms are not explicitly detailed in the provided document, the project appears to be a critical municipal infrastructure improvement initiative involving substantial engineering, tunneling, and sewer system reconfiguration. The work requires sophisticated technical capabilities, including hand mining, flow management, structural modifications, and precision underground construction techniques. The project represents a significant investment in upgrading and maintaining critical municipal water infrastructure, focusing on improving sewer system efficiency, capacity, and reliability in the Detroit metropolitan area.
