This is an Operations and Maintenance Manual Overview document related to the Mobil Microfiltration system at the Torrance Refinery Water Recycling Plant, prepared for West Basin Municipal Water District in Los Angeles County, California. The document provides technical guidance and operational parameters for the existing microfiltration equipment that has been in service since 1999. The manual covers system specifications, maintenance procedures, and operational protocols for the six-unit microfiltration system originally designed for a capacity of 3.73 MGD (518 gpm per unit). This reference document supports the feasibility study procurement, which requires selected consultants to evaluate replacement alternatives and assess the current system's operational status, deterioration factors, and restoration requirements.

The Operations and Maintenance Manual serves as a foundational technical resource for the feasibility study consultant to understand existing equipment specifications, design criteria, historical performance data, and maintenance requirements of the current system. Consultants must review this documentation to accurately assess system condition, identify deterioration patterns, establish baseline capacity metrics, and develop informed recommendations for the five minimum alternatives being evaluated, including system replacement, potable water supplementation, relocation of the Portable Ultrafiltration system, and packaged microfiltration solutions. The manual ensures consultants possess comprehensive knowledge of the legacy system's technical characteristics, operational history, and performance benchmarks necessary to conduct thorough life cycle cost analysis and return on investment comparisons for proposed alternatives.
