This file is an attachment of engineering drawings for the Great Lakes Water Authority's 42-Inch Downriver Transmission Main Loop project in Michigan. The drawings serve as technical documentation for the construction of new water transmission mains designed to create a redundant water service loop, replacing the current single, non-looped transmission main that serves GLWA customers. The drawings provide detailed specifications and design requirements necessary for contractors to develop competitive bids and execute the construction work according to engineering standards and project specifications.

The technical drawings establish the physical and operational parameters for the transmission main installation, including alignment details, depth specifications, connection points, and integration with existing infrastructure. These drawings are essential reference documents for all bidding contractors and will be used to evaluate proposal compliance, assess construction feasibility, and ensure that completed work meets GLWA's design and safety standards for the water transmission system enhancement.
