About this file
This document is Addendum #2 - Attachment B for RFP 3809, a Variable Frequency Drive (VFD) project issued by Eastern Municipal Water District (EMWD) involving six different VFD replacements across three regional water reclamation facilities: San Jacinto, Moreno Valley, and Perris Valley. The project involves replacing existing VFDs for various pumps with specifications ranging from 100 to 300 horsepower, manufactured between 1994 and 2012, and currently using brands like ABB and Toshiba.
The equipment details reveal consistent electrical specifications across the sites, with all units operating at 480 volts, 3-phase power. The VFDs have varying current output requirements from 127.65 to 340.4 amps, with most designated as ULH (Ultra Low Harmonic) units, except for one 6 Pulse unit. Motor usages include vertical turbine, centrifugal, submersible centrifugal chopper, and other pump types. The age of the existing equipment suggests this is a modernization and replacement project to upgrade aging infrastructure across EMWD's water reclamation facilities, ensuring continued reliable operation of critical water management infrastructure.
