This is an Operations and Maintenance Manual Overview document for a Mobil Microfiltration System, providing technical guidance for the Torrance Refinery Water Recycling Plant operated by West Basin Municipal Water District in Los Angeles County, California. The document serves as a reference resource for the feasibility study RFP that evaluates replacement alternatives for the existing microfiltration system installed in 1999. The current system comprises six units with a design capacity of 3.73 MGD (518 gpm per unit), though deterioration has significantly reduced operational capacity. The manual provides foundational technical information necessary for the selected consultant to conduct comprehensive analysis of system replacement alternatives, including complete system replacement, relocation of West Basin's existing Portable Ultrafiltration system, installation of microfiltration trailers or packaged systems, and alternative solution proposals. A pre-proposal meeting is scheduled for February 17, 2026, with questions and clarifications due February 19, 2026, and proposals due electronically by 2:00 PM on February 26, 2026, with contract award notification expected by March 9, 2026. The contract will be structured on a time-and-material basis with rates to be determined upon execution.

The Operations and Maintenance Manual provides technical specifications and operational guidance essential for evaluating the existing system's performance history and informing the feasibility study's preliminary design criteria and system hydraulics analysis. This document supports the consultant's development of Class 4 cost estimates, life cycle cost comparisons, and return on investment analysis across the five required alternatives. West Basin's Small and Local Business Enterprise program offers evaluation incentives including up to six additional points for SBE or LBE prime consultants and one point for qualifying subcontractors receiving at least 30 percent of contract compensation, with a 3 to 6 percent price reduction during evaluation that reverts to the original proposed price upon selection. No specific budget ceiling or award value is disclosed in the RFP documents. The selected consultant must maintain comprehensive insurance coverage including $2,000,000 Commercial General Liability and Professional Liability per occurrence, with West Basin named as additional insured, and comply with California prevailing wage requirements for applicable subconsultant labor.
