RFP-WM-3809 - variable frequency drives (VFD) over 100HP

The Eastern Municipal Water District (EMWD), serving Riverside County, California, has issued Request for Proposal (RFP) #3809 for the procurement of Variable Frequency Drives (VFDs) over 100HP across four regional water reclamation facilities in Temecula, San Jacinto, Moreno Valley, and Perris. The project encompasses two distinct components: Project 1 involves replacing two VFDs with regeneration capabilities, and Project 2 involves retrofitting six VFDs. The district seeks VFDs with Ultra Low Harmonic (ULH) technology, specifically targeting drives rated 100HP or higher, with requirements for regenerative capabilities, SCADA system integration, and compatibility with existing infrastructure. Mandatory job walks were conducted on July 22-23, 2025, with electronic proposals due by 4:00 PM on August 22, 2025. Proposers are limited to specific VFD manufacturers: Sulzer, ABB, Allen Bradley, Yaskawa, and Schneider. The evaluation criteria will include pricing, exceptions taken to the RFP, product specifications, safety record, lead times, insurance compliance, and proof of authorized partnership. The anticipated contract start date is October 1, 2025, with the supplier responsible for start-up, commissioning, and providing training to EMWD operators.

The RFP does not explicitly outline set-aside designations or restrictions for disadvantaged enterprises. Proposers must be factory-authorized dealers for the approved manufacturers and provide documentation proving their authorized status. The project involves replacing eight VFDs across facilities with existing equipment manufactured by brands like ABB and Toshiba, dating from 1994 to 2012, indicating a significant infrastructure modernization effort. While specific budget ranges are not detailed in the documents, the comprehensive technical requirements suggest a substantial investment in water infrastructure upgrade. The project includes prevailing wage requirements and will require detailed documentation, including product specifications, safety records, and comprehensive operation and maintenance manuals. Potential vendors must register on EMWD's e-Procurement website and demonstrate compliance with IEEE standards, electrical specifications ranging from 127.65 to 340.4 amps, and 480-volt, 3-phase power requirements for various pump types including vertical turbine, centrifugal, and submersible centrifugal choppers.
