These contract drawings are from the City of Detroit Water & Sewerage Department, specifically for the Evergreen-Farmington Relief Outlet Metering & Control Facilities project, with an EPA Project Number C263487-01. The documents are dated April 1986 and include detailed engineering plans for a water and sewage pollution control program. The drawings cover multiple aspects of the project, including site plans, equipment housing, reference drawings, electrical and schematic diagrams, junction chamber details, and various facility sections. The project involves constructing regulatory facilities, including first and second stage interceptor systems, with comprehensive technical specifications for infrastructure components like sewer lines, chambers, gates, electrical systems, and monitoring equipment.

The drawings are prepared by the Board of Water Commissioners, with key personnel including William G. Herbert as President and Charlie J. Williams as director. The technical documentation provides extensive engineering details for a complex water infrastructure project, including precise measurements, elevation profiles, electrical circuit diagrams, and installation specifications. The project appears to be a significant municipal infrastructure upgrade focusing on sewage management, flow control, and monitoring capabilities, with meticulously drafted technical drawings that outline every structural and operational detail of the proposed facilities.
