Supply of Reverse Osmosis (RO) Membranes for Torrance Refinery Water Recycling Plant

West Basin Municipal Water District is seeking qualified bidders to supply eight hundred seventy-six (876) reverse osmosis (RO) membrane elements for the Torrance Refinery Water Recycling Plant (TRWRP) located in El Segundo, California. The procurement involves replacing membrane elements in four reverse osmosis trains that treat tertiary effluent from the Edward C. Little Water Recycling Facility. Acceptable membrane models include Toray TM720D-400, LG BW400AFR, and Hydranautics CPA5-LD, with specific performance requirements for individual element and lot acceptance testing. The project requires membranes that meet ISO/9000-9001 manufacturing standards and NSF certification, with eight hundred forty (840) membranes to be initially installed and thirty-six (36) held as spares. Quotations are due on October 17, 2025, at 2:00 pm, with a 90-day delivery requirement from the Notice of Award, and bidders must submit responses electronically through the OpenGov e-procurement system. The RO system is designed for a permeate flow of one million gallons per day at 85 percent recovery, with an average operating flux of approximately 11.9 gallons per square foot per day.

The district has implemented a Small and Local Business Enterprise Program that provides evaluation incentives, offering a 3% quotation reduction for Small Business Enterprises (SBE) or Local Business Enterprises (LBE), with an additional 3% reduction if a vendor qualifies as both. Vendors must complete a Vendor Information Request form and provide comprehensive company details, including W-9 information and small business enterprise certification status. The procurement includes specific insurance requirements, with vendors needing to maintain Commercial General Liability of at least $2,000,000 per occurrence, Automobile Liability of $1,000,000 per accident, and Workers' Compensation insurance. The project includes a three-year warranty period from the start of System Performance Testing, with prorated replacement conditions for membrane elements that fail to meet performance requirements. Pricing will include line items for membrane elements, spare parts, sales tax at 9.75%, and freight, with the district evaluating the lowest responsive quotation for potential award subject to Board of Directors' approval. The estimated project budget is not explicitly stated, but the comprehensive specifications and detailed requirements suggest a significant investment in water recycling infrastructure.
