The San Juan Capistrano project was constructed by ARB to provide the City of San Juan Capistrano, California with a reliable source of good, safe drinking water by recovering and treating previously unusable brackish groundwater.
Water and Wastewater Treatment Plant Project
The project will allow the City to reduce its dependence on imported sources such as the Colorado River and Northern California currently supplied by the Metropolitan Water District, and is one of the first public-private partnerships under the MWD`s Groundwater Replenishment program. MWD approved the project in December of 2002. ARB provided full-service construction services in partnership with Boyle Engineering and Southwest Water Company.
San Juan Capistrano Treatment Plant Utilizing Reverse Osmosis
The process utilizes reverse osmosis, or RO, which is used by many bottled water companies and home water purifiers. Incoming well water is passed through semi-permeable membrane elements under high pressure, removing unwanted mineral particles, some as small as individual molecules, after having first been passed through a series of filters. Capacity: 5.14 MGD or 4800 acre-feet of water per year. One acre foot of water is about 326,000 gallons, the amount of water it takes to cover an acre to a depth of one foot, or the amount two families of four would use in a year. Upon completion, this ARB constructed facility will supply virtually all the City`s water needs during the winter months, and about half the water it needs during the summer months. ARB installed over five miles of pipeline as part of this project in order to bring the water from the wells to the plant to be processed.
Valero Refinery Project
Valero had experienced flame instability and impingement on radiant shock tubes in one of their crude heaters. The deficiency was due to a high-pressure drop in the transition ducting from the convection section to the stack, in addition to air leaks through the doors and joints. The leaks allowed cold ambient air to enter the furnace and increase flue gas, which decreased burner draft. This turnkey assignment was a complete design-build project. ARB`s scope of work included enlarging the size of the three ducts, which necessitated the removal of the stack. Enlarging the ducts reduced the pressure drop and increased draft at the burners, and also provided more uniform flow in the convection section, increasing heater efficiency. Leak points at the doors, flanges and joints were also repaired to eliminate cold ambient air entry into the furnace.
All American Asphalt Structural Steel Project
Corona, California ARB installed (6) 1000 ton aggragate silos with support structure, truck scales and associated conveying system.
Chevron USA Structural Steel Project
El Segundo, California installation of over 2,000 tons of structural steel, 26,000 square feet of grating and well in excess of 1 mile of handrail, ladders and stairs. Over 2,000,000 man hours were expended on this project with no lost time injuries.
Soka University Structural Steel Project
