Mobil CMF O&M Manual Overview

This is an operations and maintenance manual document related to West Basin Municipal Water District's feasibility study for the Microfiltration System Replacement at the Torrance Refinery Water Recycling Plant (TRWRP) in Los Angeles County, California. The document provides technical guidance for the Mobil Cartridge Microfiltration (CMF) system, which represents the existing equipment installed in 1999 consisting of six units with a designed capacity of 3.73 MGD (518 gpm per unit). The feasibility study, for which this manual serves as reference material, requires the selected consultant to evaluate a minimum of five alternatives for addressing the system's deterioration and capacity reduction: continuing current operations with potable water supplementation, complete replacement of microfiltration effluent with potable water, relocation and installation of West Basin's existing Portable Ultrafiltration system, installation of microfiltration trailers or packaged systems, and proposing alternative solutions. The pre-proposal meeting is scheduled for February 17, 2026, with questions and clarifications due by February 19, 2026, and proposal submissions required electronically by 2:00 PM on February 26, 2026, with contract award notification expected by March 9, 2026.

Compensation for the feasibility study will be structured on a time-and-material basis with rates and not-to-exceed amounts to be determined upon contract execution, with monthly invoices submitted in arrears and payment issued within Net 30 days of receipt; no specific budget range or award value is provided in the RFP documents. West Basin has established a Small and Local Business Enterprise (SLBE) program offering three additional evaluation points for SBE or LBE prime consultants (six points if both designations apply) or one point if SBE/LBE subcontractors receive at least 30 percent of total contract compensation, with price proposals for qualifying firms reduced by 3 percent (or 6 percent if both designations apply) during evaluation. No incumbent vendor or current contractor is identified, indicating this represents a new engagement. The consultant must obtain comprehensive insurance coverage including Commercial General Liability of $2,000,000 per occurrence, Business Automobile Liability of $2,000,000 per accident, Workers' Compensation with statutory limits and $1,000,000 Employer's Liability coverage per accident, and Professional Liability of $2,000,000 per occurrence, with West Basin named as an additional insured with primary coverage status.
