This is an electrical installation single line diagram for a water treatment or pumping facility operated by the Bureau of Reclamation. The drawing illustrates the power distribution system architecture and control logic for the facility, which includes two Uninterruptible Power Supply (UPS) units (UPS 1 and UPS 2 Bypass Panels), battery charging infrastructure, and a control room. The single line diagram shows connections between multiple components including Power Distribution Units (PDUs), Power Conditioning Modules (PCMs), Pilot Distribution elements (PID1, PID2), and various control and monitoring equipment. The system incorporates a battery charging room and control room, with interconnections to external power sources via KHD connections. The diagram references multiple related specification and engineering documents including equipment plans, removal plans, panel schedules, power cable and conduit schedules, and revised equipment specifications. The document number is 557-D-60172, and the drawing is part of a larger set of reference drawings for a water infrastructure project managed by the Bureau of Reclamation. This is a technical engineering drawing rather than a contract solicitation or statement of work.
