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

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.

Program Management and Operations Support of Water Works Projects 
City of South Gate

SAFNA is currently supporting the City’s water infrastructure program as the program managers, providing day-to-day project management, technical oversight of design, permitting support, system operations support, and management of contractors and consultants. The City is building a potable water reservoir, a booster pump station, a new groundwater well, and expanding the region’s recycled water system. The projects will increase the reliability and efficiency of the City’s water system. The new Well No. 29 has been completed and is currently operating. SAFNA has certified D5 and T4 staff and is assisting the City with incorporating the operations of the well into the existing system, as well as developing efficient operating methods to ensure the well is fully utilized.

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

San Gabriel Valley Indirect Potable Reuse Program 
San Gabriel Valley

For over five years, SAFNA’s Executive Director served as the Chief Engineer and Program Manager leading the program development and implementation of a $75 Million Indirect Potable Reuse (IPR) project located in the San Gabriel Valley. The project consisted of delivering up to 10,000 acre-feet per year of highly treated tertiary water into the Santa Fe Spreading basins to supplement the receding groundwater levels, via a pump station and a nine-mile-long large diameter pipeline.

​Successful program development required management of a team of staff, consultants, and coordination with local stakeholders. The program involved the preparation of a programmatic feasibility study, in-depth groundwater modeling, preparation of the pipeline right-of-way and easement requirements, and permitting and right-of-way coordination with the State Department of Public Health, the Regional Board, the Army Corps of Engineers, the Sanitation Districts of Los Angeles County, and numerous local stakeholders.

LARGE LANDSCAPE SURVEY AND RETROFIT PROGRAM MANAGEMENT AND IMPLEMENTATION 
San Gabriel Valley

Prior to joining SAFNA, our professional staff served on the program management team responsible for the development and implementation of the Large Landscape Survey and Retrofit Program in the San Gabriel Valley. The program involved coordination of site surveys and construction retrofit activities with 19 water purveyors, 125 schools, 10 industrial commercial sites, 30 Parks and 12 cities. Successful management of the program involved the preparation of grant application packages for the project, resulting in successful grant awards of $2.4 Million from federal (USBR) and state (DWR) agencies.

​The program consisted of two phases. The first phase involved surveys to examine a site’s existing irrigation system, including irrigation controllers, valves, and sprinkler heads. The outdoor water use survey report identified water use on each site and recommendations on where water savings was available. The second phase involved construction crews to repair old broken irrigation systems and upgrade equipment to reduce water usage based on survey recommendations. New technology, such as weather-based irrigation controllers, and high efficiency water nozzles were installed. The program manager was responsible for directing all work assignments; designing the retrofits; completing onsite shut-down tests and coordinating closely with clients, various cities, the County DPH, service providers, school districts, contractors, and staff in multiple offices.
