42 • October 2018 As an industrial operator in California, particularly with high desert, San Bernardino County acreage hovering Los Angeles, Clark Pacific needs little incentive to conserve fresh water, capture non-process area runoff, and recycle process water. At the Adelanto plant, management is especially keen on the latter: Water from the plant mixers, mixer trucks and batch plant areas is settled in 13-ft. wide weirs, automatically adjusted to target pH levels by a Fortrans carbon dioxide treatment system, then conveyed to a Water Treatment Solutions EnviroSystem Model #15. With a 15-cu.-ft. filter press of 30 800-mm square plates, the EnviroSystem is equal to 100-gallon/minute treatment rates. Post-press water is pumped to a 3,000-gallon cone bottom storage tank sup- plying the batch plant plus mixer and truck washout areas through 2-in. lines. Process water treatment and recycling, coupled with strong adherence to environmental and safety rules or regulations, demonstrate a commitment to sustainabil- ity at the Adelanto plant mirroring that of Clark Pacific's West Sacramento flagship. The Business Environmental Resource Center presented the company the 2018 Sac- ramento Sustainable Business of the Year award for green building, recognizing employers for sustainabil- ity-driven work practices. The Center particularly noted the producer's "dedication to environmentally friendly manufacturing and construction methods and significant reduction of environmental impacts at hundreds of construc- tion sites across California." "This is a testament to our efforts over the years to refine our environmental policies and the awareness we place on how our work can make a positive impact on sustainability and the environment," says Clark Pacific Environmental Manager Richard Maddux. "We look forward to making even greater sustainability contributions to all the communities we serve in the years to come." COVER STORY BY DON MARSH STRESSING SAFETY AND SUSTAINABILTY Mindful that worker safety and environmental management are top sustainability program priorities, Clark Pacific stresses the "One Company. One Life. Zero Injury." message throughout the Adelanto plant, from the gate, to the double tee bed, to a steel fabrication shop laden with welder protection gear and air quality assurance. The Water Treatment Solutions EnviroSystem filter press and Fortrans CO 2 pH adjustment, plus settling and storage vessels, support water recycling key to sustainability measures at Clark Pacific's newest plant in Adelanto.
