To provide variable pumping the existing low lift, two-speed, 4kV pump motor was rewound to 460 volts and a variable frequency drive (VFD) was installed.  Two existing transformers were removed and replaced with a single 480-volt transformer and a new double-ended motor control center (MCC) was installed.  The VFD was interfaced with the Electric Station PLC for automatic and remote control of the pumping from the SCADA system.
