This is a Scope of Work document for the West Basin Municipal Water District in Los Angeles County, California, detailing professional engineering services for a feasibility study of the Microfiltration System Replacement at the Torrance Refinery Water Recycling Plant. The existing microfiltration system, installed in 1999 with six units designed for 3.73 MGD capacity (518 gpm per unit), has deteriorated significantly and requires replacement to restore and increase water production capacity. The selected consultant must evaluate a minimum of five alternatives: 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. 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. The pre-proposal meeting is scheduled for February 17, 2026, with respondent questions due by February 19, 2026, and proposals submitted electronically by 2:00 PM on February 26, 2026, with contract award notification expected by March 9, 2026. The consultant must conduct a kick-off meeting, biweekly progress meetings with earned value analysis reporting, site utility searches, and a final presentation.

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 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 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. The consultant must 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 of $2,000,000 per occurrence, with West Basin named as an additional insured. No incumbent vendor or current contractor is identified, and California prevailing wage requirements apply to any subconsultants providing labor on tasks with established state prevailing wage classifications.
