The file SAN-1233EV-RD-MI-CONT3-SHT14OF17.TIF is a technical specification document for the Walnut Lake No. 2 Conveyance CAP Phase II project, involving Detroit Water and Sewerage Department (DWSD) and Great Lakes Water Authority (GLWA) in Michigan. The comprehensive infrastructure project includes multiple critical sewer system modifications, such as 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 installing new sanitary sewer tunnels and connections. The project encompasses structural, electrical, and telemetry components, with specific tasks including constructing new 66-inch and 78-inch diameter sanitary sewers, abandoning existing sewer lines, and installing a new 96-inch sluice gate with electrical connections.

The project will involve significant civil engineering work, including site concrete work, asphalt paving, grading, and landscaping along the M-39 Southfield Freeway and M-102 West Eight Mile Road. While specific pricing details are not provided in the document, the project appears to be a substantial municipal infrastructure investment aimed at improving sewer system efficiency and capacity. The work requires specialized construction techniques such as hand mining and tunnel construction, suggesting a complex and technically challenging infrastructure upgrade that will likely involve significant capital investment from municipal and regional water management authorities.
