Middletown Water Booster Station Improvements

Key Accomplishments

Johnston Construction Company

• The project included replacement of the existing motors on two vertical split-case booster pumps with new inverter-duty motors.
• JCC installed two Owner-furnished 100-horsepower variable frequency drives and completed the associated mounting, conduit, power wiring, control wiring, and equipment connections.
• The existing packaged booster-skid system, jockey pumps, steel piping, valves, and hydropneumatic tanks were demolished and removed.
• New ductile-iron suction and discharge piping, valves, supports, and associated process components were installed within the station.
• JCC coordinated relocation and temporary operation of the existing remote terminal unit so the Town’s monitoring and control functions remained available during construction.
• The project included electrical, instrumentation, grounding, control, testing, painting, door replacement, startup, training, and final closeout activities.
• Johnston Construction Company served as the prime contractor for the Water Booster Station Improvements project for the Town of Middletown in Frederick County, Maryland.
• The project was located at the Town’s existing booster-station facility on Water Plant Road, off East Main Street in Middletown.
• The work upgraded the station’s pumping, piping, electrical, instrumentation, and building systems while maintaining continuous water service to the Town’s distribution system.
• The primary purpose of the project was to modernize the existing booster-pumping system and improve operational control, reliability, and efficiency.
• The existing motors on two vertical split-case water booster pumps were replaced with new inverter-duty motors designed for operation with variable frequency drives.
• The project also removed an existing packaged booster-skid system that included jockey pumps, steel piping, valves, and hydropneumatic tanks.

Electrical Services Division

• Electrical Services Division, LLC performed the electrical construction work supporting the Town of Middletown Water Booster Station Improvements project.
• ESD furnished and installed conduit, wire, boxes, devices, connections, switchgear components, and supporting electrical materials throughout the booster station.
• The work included installation of a new lighting panel and equipment rack serving the upgraded station systems.
• ESD completed electrical demolition associated with removal and replacement of the existing booster-station equipment.
• Temporary electrical service and power provisions supported ongoing facility operations during construction.
• The project included heat-tracing circuits, grounding and lightning-protection work, electrical inspections, testing, and startup support.
• ESD coordinated its installation with new booster-pump motors, variable frequency drives, process piping, instrumentation interfaces, and the existing remote terminal unit.
• The electrical work was sequenced with JCC’s temporary pumping, mechanical construction, equipment replacement, and system-startup activities.
• Electrical Services Division, LLC performed the electrical portion of the Water Booster Station Improvements project at East Main Street and Coblentz Road in Middletown, Maryland.
• The overall project upgraded the Town of Middletown’s existing water booster station. Johnston Construction Company served as the prime contractor, and ESD performed the electrical work as JCC’s electrical subcontractor.
• The project involved replacement of motors on two existing vertical split-case water booster pumps, installation of variable frequency drives, demolition of an existing packaged booster system, new process piping and valves, exterior-door replacement, instrumentation work, testing, and startup.
• The subcontract required ESD to furnish the labor, materials, tools, equipment, and supervision necessary for the project’s electrical work in accordance with the electrical drawings, Division 16 specifications, project addenda, approved proposal, and control estimate.
• ESD’s work began with coordination of the existing station electrical systems and the planned construction sequence.
• The booster station had to remain operational while major mechanical and electrical equipment was removed and replaced.
