Atlanta, GA Work encompasses the complete replacement of four high service pumps at the Chattahoochee Water Treatment Plant, including removal and disposal of existing Pumps #1, #2, #3, and #4, conditioning and modification of existing pads for new equipment, and offloading, setting, leveling, and grouting of new pump assemblies. The scope includes touch-up painting of existing pipe near work areas and installation of miscellaneous pipe, fittings, and adapters to connect to existing discharge piping systems.
Electrical work includes removal of existing medium voltage starters and installation of new medium voltage VFDs and soft starts, furnishing and installing 5 KV power cable between new drives and motors (reusing existing floor conduit), and running 5 KV power cable between four new drives and existing medium voltage switchgear. All medium voltage cables are hi-pot tested before energizing. The project includes installation of conduit and wiring for digital and analog signals from new drives to existing PLC panels per NEC requirements, connecting RTD temperature sensors on new motors to drives, and installation of ball valves and valve control panels.
Our team provides complete startup assistance to ensure seamless integration of new pump systems with existing plant operations and SCADA infrastructure.
These raw water pumps are critical to the City of Atlanta being able to service water to majority of the CIty. The raw water pumps are being replaced one at a time and allowing time for startup and run time prior to starting the next pump to ensure success.
