This is a Standard Operating Procedure (SOP) document for the Torrance Refinery Water Recycling Plant (TRWRP) Microfiltration Feasibility Study, prepared for West Basin Municipal Water District serving Los Angeles County, California. The document outlines the professional engineering services required 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 significantly deteriorated. 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. The pre-proposal meeting is scheduled for February 17, 2026, with questions and clarifications due by February 19, 2026, and proposal submissions required by 2:00 PM on February 26, 2026. Contract award notification is expected by March 9, 2026. 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.

Compensation will be structured on a time-and-material basis with rates and not-to-exceed amounts determined upon contract execution, with monthly invoices submitted in arrears and payment issued within Net 30 days. West Basin's Small and Local Business Enterprise (SLBE) program offers evaluation incentives, including three additional points for SBE or LBE prime consultants (six points if both apply) or one point if SBE/LBE subcontractants receive at least 30 percent of total contract compensation, with price proposals reduced by 3 percent (or 6 percent if both designations apply) during evaluation. No incumbent vendor is identified for this new feasibility study engagement. Consultants 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 per accident, and Professional Liability of $2,000,000 per occurrence, with West Basin named as additional insured with primary coverage. California prevailing wage requirements apply to any subconsultants providing labor on tasks with established state classifications. No specific budget range or award value is provided in the RFP documents.
