The file SAN-1233EV-RD-PP-CONT3-SHT16OF17.TIF is a project document for the Walnut Lake No. 2 Conveyance CAP Phase II, involving the Detroit Water and Sewerage Department (DWSD) and Great Lakes Water Authority (GLWA) in Michigan. The comprehensive infrastructure project includes the removal and replacement of existing sewer siphon pipes, with multiple critical components such as constructing temporary bypass conduits, slip lining and grouting existing siphons, modifying junction and meter chambers, and installing new sanitary sewer tunnels and connections. The project scope encompasses structural, electrical, and telemetry work, including the procurement and installation of a new 96-inch sluice gate with electrical connections, and involves abandoning several existing sewer lines ranging from 21 to 78 inches in diameter.

The project will take place along the M-39 Southfield Freeway and M-102 West Eight Mile Road, with significant infrastructure improvements that include site 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 sewer system modernization and capacity enhancement. The work involves complex engineering and construction techniques, including hand mining, tunnel construction, and precise hydraulic system modifications, indicating a sophisticated and technically demanding municipal infrastructure project.
