SAN-1233EV-RD-PP-CONT3-SHT9OF17.TIF

The document SAN-1233EV-RD-PP-CONT3-SHT9OF17.TIF is a project specification related to a critical sanitary sewer infrastructure project involving Detroit Water and Sewerage Department (DWSD) and Great Lakes Water Authority (GLWA) in Michigan. The project, named Walnut Lake No. 2 Conveyance CAP Phase II, encompasses comprehensive sewer system modifications, including removing existing 78-inch and 66-inch diameter siphon pipe connections, constructing temporary bypass conduits, slip lining and grouting existing pipes, modifying junction and meter chambers, and installing new sanitary sewer tunnels and connections. Key construction elements include creating new 66-inch and 78-inch diameter sewer tunnels, abandoning existing sewer lines, constructing a new manhole on the M-39 Southfield Freeway, and installing a new 96-inch sluice gate with electrical connections.

The project involves substantial infrastructure upgrades requiring complex engineering and construction techniques, with work concentrated in the Detroit metropolitan area. While specific pricing details are not provided in the document, the scope suggests a significant capital investment in municipal water infrastructure. The project appears to be funded through municipal or regional infrastructure budgets, likely involving a combination of local government and potential state or federal infrastructure funding sources. The comprehensive nature of the work indicates a strategic approach to updating and improving regional sewer system capacity, reliability, and performance, with a focus on maintaining continuous flow and addressing aging infrastructure challenges.
