SAN-1233EV-RD-SD-CONT3-SHT12OF17.TIF

The file SAN-1233EV-RD-SD-CONT3-SHT12OF17.TIF is a technical document related to a sewer infrastructure project involving the Detroit Water and Sewerage Department (DWSD) and the 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 installing temporary bypass conduits, slip lining existing 66-inch and 78-inch diameter siphons with a 54-inch pipe, modifying junction and meter chambers, constructing new sewer segments ranging from 21 to 96 inches in diameter, and abandoning multiple existing sewer lines along the M-39 Southfield Freeway and M-102 West Eight Mile Road.

The project involves complex infrastructure engineering with significant structural, electrical, and telemetry modifications, including procurement and installation of a new 96-inch sluice gate with electrical connections. While specific pricing details are not provided in the document, the project appears to be a substantial municipal infrastructure investment requiring specialized engineering and construction capabilities. The scope suggests a comprehensive rehabilitation and expansion of the existing sewer system, with work concentrated in the Detroit metropolitan area. The project demonstrates a strategic approach to updating critical water infrastructure, focusing on improving flow management, structural integrity, and operational efficiency of the existing sewer network.
