This is an Operations and Maintenance Manual overview document related to a microfiltration system feasibility study for West Basin Municipal Water District's Torrance Refinery Water Recycling Plant (TRWRP) located in Los Angeles County, California. The RFP solicits professional engineering services to conduct a comprehensive feasibility study for replacing the existing microfiltration system, which was installed in 1999 with six units designed for 3.73 MGD capacity (518 gpm per unit) but has deteriorated significantly. The consultant must evaluate a minimum of five alternatives: continuing current operations with potable water supplementation, complete replacement 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. Deliverables include a comprehensive feasibility study with preliminary design criteria, system hydraulics analysis, environmental impact assessments, regulatory compliance review, Class 4 cost estimates, life cycle cost comparisons, and return on investment analysis for each alternative, submitted in draft, draft final, and final stages with documentation in CAD, GIS, PDF, and Microsoft formats. The pre-proposal meeting is scheduled for February 17, 2026, with respondent questions due by February 19, 2026, and proposals due electronically by 2:00 PM on February 26, 2026, with contract award notification expected by March 9, 2026.

Compensation will be structured on a time-and-material basis with rates and specific not-to-exceed amounts determined upon contract execution, with monthly invoices submitted in arrears and payment issued within Net 30 days; no specific budget range or award value is identified in the RFP documents. West Basin has established a Small and Local Business Enterprise (SLBE) program offering evaluation incentives for qualified participants, including three additional 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. Consultants must obtain and maintain 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 (Errors and Omissions) of $2,000,000 per occurrence, with West Basin named as additional insured with primary coverage status. California prevailing wage requirements apply to any subconsultants providing labor on tasks with established state prevailing wage classifications.
