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 replace the entire electrical distribution system supported with redundant Emergency Generator System and new Pulse Width Modulated Variable Frequency Drives for the pumps.

Upon the acceptance of these recommendations, METCO in association with Greeley & Hansen had developed detailed design and construction documents to implement the following recommended improvements:

·         New Primary and Secondary Electrical Distribution System with two primary DTE feed.

·         New line-up of 5KV Switchgear

·         New VFD System for three pumps

·         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 final construction documents were approved by DWSD and the bidding process is on-going.
