Edgar Road Water Pumping Station Improvements

Key Accomplishments

• The project included installation of a new automatic transfer switch serving the normal and emergency electrical sources at the pumping station.
• BRE installed new phase-monitoring equipment within the automatic transfer-switch enclosure to monitor the normal and emergency feeders and provide remote alarm signals to the existing station control system.
• The work included field investigation, demolition, conduit, wiring, and connections associated with the existing LC3000 control panel and pumping-station instrumentation.
• BRE coordinated the electrical installation with Howard County’s SCADA-system supplier, Whel-Tech, Inc. and Primex, to integrate feeder-failure signals with the existing pumping-station and County master SCADA systems.
• BRE coordinated short-circuit, protective-device coordination, load-flow, voltage-drop, and arc-flash hazard studies for the upgraded electrical system.
• The project was identified as Howard County Capital Project No. S-6600, Contract No. 44-5202, and Invitation for Bids No. 2023-31. The contract documents required structural, mechanical, electrical, communication, instrumentation, and control improvements to the existing water pumping station.
• BRE’s work focused primarily on replacement and modernization of the pumping station’s electrical distribution and control infrastructure.
• The project included demolition and removal of existing electrical, communication, instrumentation, and control components, followed by installation, connection, testing, and commissioning of the new systems.
• BRE coordinated the overall electrical construction effort, including project management, scheduling, submittals, electrical demolition, equipment procurement, conduit installation, conductor installation, grounding, automatic transfer equipment, switches, circuit breakers, instrumentation wiring, SCADA coordination, electrical studies, inspections, testing, startup, training, and closeout.
• The electrical demolition work included investigation and identification of the existing electrical circuits and control connections affected by the pumping-station improvements.
• BRE disconnected and removed designated conductors, raceways, circuit-protection equipment, control wiring, instrumentation connections, and related components while protecting the existing systems required to remain in operation.
• The project included extensive installation of low-voltage power conductors and cables.
