Schoolcraft Pump Station Upgrade

DWSD required the existing obsolete variable controllers for the pumps to be replaced along with upgrading the Electrical Distribution System at Schoolcraft Pump Station. In response to this need, METCO performed a comprehensive study with recommendation to upgrade their existing pumps, VFD drive, motor and associated electrical distribution system supported with redundant Emergency Generator System. Upon the acceptance of these recommendations, METCO had developed detailed design and construction documents to implement the following recommended improvements: - Three (3) horizontal, split casing centrifugal Pumps each rated for 35 cfs at 170' TDH, with 1,000 HP, 4160V, Induction Motor - Three (3) new Medium Voltage, 1000 HP air cooled VFD's - New Primary and Secondary Electrical Distribution System with two primary DTE feed - New line-up of 5KV Switchgear - New Electrical Building to accommodate these drives - New HVAC System to support the VFD Units - 2x2 MW - New Diesel Emergency Generator System with associated Fuel Supply System The construction documents also included extensive construction sequencing to implement this work with minimal interruption to the Pump Station operation. The project was completed within the schedule time frame of 24 months and at a total cost of approximately $14.2 Million.
