The file SAN-1233EV-RD-MI-CONT3-SHT14AOF17.TIF relates to a Michigan state infrastructure project involving the Detroit Water and Sewerage Department (DWSD) and Great Lakes Water Authority (GLWA) for the Walnut Lake No. 2 Conveyance CAP Phase II project. The comprehensive sewer infrastructure renovation encompasses multiple critical components, including removing existing 78-inch and 66-inch diameter sewer siphon pipes, constructing temporary flow bypass conduits, slip lining and grouting existing siphons with a 54-inch pipe, modifying junction and meter chambers, and constructing new sanitary sewer tunnels and connections. The project involves extensive underground infrastructure work, including tunnel construction, sewer line replacements, chamber modifications, and installation of a new 96-inch sluice gate with electrical connections.

The project scope includes significant civil engineering work across multiple sites, with specific focus on infrastructure improvements along the M-39 Southfield Freeway and M-102 West Eight Mile Road. The work will involve abandoning existing sewer lines, constructing new tunnels and connections, and completing associated site work such as concrete work, asphalt paving, grading, and landscaping. While specific pricing details are not provided in the document, the project represents a substantial municipal infrastructure investment targeting critical wastewater management and conveyance improvements in the Detroit metropolitan area, likely funded through municipal infrastructure budgets or state/federal infrastructure grants.
