Los Angeles Community College Districts (LACCD)
Facilities Program and Construction Management

SAFNA Engineering and Consulting is part of the Program Management Team supporting various aspects of the Los Angeles Community College Districts $3.4 Billion program. The program is aimed to construct new facilities, improve existing campus facilities, and improve
facility resources for the growing student population. The LACCD has nine campuses, and two satellite campuses located throughout Los Angeles County. The facilities have been implemented using traditional design-bid-build practices. However, the deployment of future
projects may follow Design-Build practices to help expedite project implementation during the next five-year bonding window to complete most of the program. SAFNA is providing project controls, project administration, and project management support services on the program as part of the program management team.

SUNLINE TRANSIT AGENCY
Evaluation of Chillers and Cooling Towers During the Construction of a New Hydrogen Facility

SAFNA provided technical advisory and engineering support services during the evaluation of a cooling system for a new Hydrogen Generation Facility for Sunline Transit Agency in the Coachella Valley. The services involved the review and evaluation of two major systems including cooling towers and traditional chillers. SAFNA also looked at various options of utilizing the brine water discharge, including developing ways of further treating and recycling the system water discharge for onsite irritation as a reclaimed water source. SAFNA prepared technical recommendations that outlined the different options that the Agency can implement to address the impacts of chiller-based cooling system to a cooling tower-based system.

WEST VALLEY WATER DISTRICT
Preparation of Grant Funding Applications for United States Bureau of Reclamation

SAFNA provided technical advisory and grant writing support services for the preparation of several grant applications for the agency’s Advanced Metering Infrastructure Project. WVWD will improve water use efficiency by upgrading the existing water meter data management system with Advanced Metering Infrastructure (AMI) for over 3,000 metered connections in the WVWD service area. WVWD will attach new Radio Transmission Units (RTUs), endpoints and new meter lids to all the existing metered connections. This technology will allow WVWD to remotely manage metering assets and detect leaks immediately and allow WVWD customers the ability to view water usage, set alerts, and gather reports about their home water system on an hour-by-hour basis through the wireless sensor network.

Carlsbad Desalination Project
Carlsbad, California

As one of SAFNA’s featured projects, the Carlsbad Desalination plant provides 50 MGD of water to approximately 300,000 residents in San Diego. One of the most critical processes and components of the plant was the selection and design of a pre-treatment process. SAFNA was part of the design-build team responsible for designing innovative pre-treatment filtration vessels (patent-pending) that extend the life of the plant’s Reverse Osmosis equipment and meet NSF 61 requirements. Running highly corrosive seawater through treatment equipment at 250 psi of pressure posed water quality and structural integrity challenges. The experienced SAFNA team selected natural polypropylene as the internal structural cage. A total of 17 multi cartridge filter vessels were designed and manufactured at the SAFNA facilities in San Dimas, CA. The vessels were made of carbon steel, lined with Endura-flex that offered several benefits to the project including cost savings, reduced maintenance, and equipment longevity. Among the key design services provided by SAFNA’s engineers includes:

• Design of Pressure Vessel Using ASME CODE, Section VIII, Division 1 
• ASME Design and Code Verification Software
• SolidWorks modeling and simulation to determine internal material deflection and wear based on variable flow rates and water pressure
• Utilized SolidWorks to Create 3D Model
• Stress Analysis
• Prepared all Seismic Calculations
• Developed Torque and Setting Specifications
• Generated Operations Manual
• Hydrostatic Testing
• Prepared Manufacturing Drawings and Weld maps using AutoCAD 
• NSF-61 Certification, Design and Testing
• Fabrication of All Vessels at SAFNA’s San Dimas, CA Facility​​

Metropolitan Water District of Southern California F.E. Weymouth Treatment Plant
La Verne, California

The Metropolitan Water District completed the F.E. Weymouth Treatment Plant in 1940. It serves the county residents of Los Angeles and Orange. To enhance its output and lower chlorine levels, a plant retrofit was planned to disinfect primarily with ozone. Construction is underway for an ozone water treatment process which, when completed in 2017, will make Weymouth the final Metropolitan treatment plant retrofitted for ozone disinfection. Compared to chlorine, ozone destroys a wider range of micro-organisms, produces fewer byproducts and removes unpleasant tastes and odors more effectively. When using ozone, bromate is produced as a byproduct and requires additional treatment to manage.
SAFNA designed three very specific and customized 10,600-gallon sulfuric acid storage tanks made with carbon steel to address this issue. The in-house design and production of the project tanks included:

• Engineered to API Standard
• Used API Modeling Software to Confirm Design Conformity
• Prepared all Seismic Calculations for Tank Anchors
• Hydrostatic Testing
• Prepared All Manufacturing Drawings and Weld Maps using AutoCAD
• Design and Fabricated Tanks at the SAFNA San Dimas, CA Facility​

Irvine Ranch Water District – Michelson Water Recycling Plant - Biosolids and Energy Recovery Facilities
Irvine, California

The Michelson Water Reclamation Plant treats thousands of gallons of wastewater to produce reclaimed water for irrigation applications. The wastewater treatment process also produces a nutrient rich by-product referred to as biosolids. This new facility will utilize a biological and heat process to convert the biosolids into fertilizers, and utilize the resulting biogas as a fuel to generate electricity. SAFNA was responsible for designing and fabricating two stainless steel utility water tanks (8,600 gallons each) along with one sodium hydroxide storage tank (CS) as part of the project. Engineers estimate that this facility will save IRWD customers $10 million a year over the next 20 years. Below are some of the design aspects of the tasks assigned to SAFNA:

• Engineered to API Standard
• Used API Modeling Software to confirm design conformity
• Seismic Calculations for Tank Anchors
• Hydrostatic Testing
• Prepared All Manufacturing Drawings and Weld Maps using AutoCAD 
• Design and Fabricated Tanks at the SAFNA San Dimas, CA Facility

Santa Barbara County – Tajiguas Landfill
Santa Barbara, California

Operational since 1967, the Tajiguas Landfill processes up to 23.3 million cubic yards of waste over 118 acres. Landfill gas emissions consist of methane, carbon dioxide and hydrogen sulfide, which abide by air- quality EPA requirements but can be dangerous at high levels. SAFNA created a treatment solution that lowered these gas emissions.

• Structural integrity engineering with formed tubular members to withstand vacuum/pressure conditions
• Calculated 4G lifting lugs
• Prepare Seismic Calculations and Footing Recommendations
