1-Attachment A - B4138 Brosseau Booster-Modified Single-Line.pdf

This document is an electrical single line diagram for the Brosseau Pumping Station Transfer Switch Installation, created by Envwd (likely Environmental Water District). The technical schematic depicts a complex electrical system with multiple components including RTU (Remote Terminal Unit) controls, HOA (Hand-Off-Auto) switches, circuit breakers, and power transformers. The diagram shows three separate electrical circuits or paths, each with its own heater, control mechanisms, and power distribution elements. Red annotations indicate modifications, measurements, or notes about specific components and connections.

The diagram appears to be part of an engineering design for upgrading or documenting electrical infrastructure, specifically focused on power transfer and control systems for a pumping station. The technical drawing includes detailed electrical connectivity information, showing how different electrical components are interconnected, their voltage specifications, and control mechanisms. The schematic provides a comprehensive view of the electrical system's layout, which would be crucial for installation, maintenance, and potential future modifications of the pumping station's electrical infrastructure.
