Our “Central Park” at out headquarters campus in Irvine, California is designed to collect rain water for filtering and re‐use on our campus landscaping. The storm water harvesting tanks serve two primary environmental purposes: 1) by collecting storm water runoff, we are able to prevent potentially contaminated rain water from being released to the environment, and 2) by reusing the storm water on our landscaping, we are able to help conserve water and reduce adverse impacts during periods of drought.
Our harvesting system consists of two 30,000-gallon underground storage tanks, which are designed to collect and treat 120,000 liters of water per inch of rainfall. Our typical average rainfall ranges from 10 to 15 inches per year, equivalent to collecting, treating and recycling 1,200 to 1,800 m3 per year. In order to further conserve water and enhance the enjoyment of our campus, we replaced the natural grass with artificial turf in 2018. This allows us to conserve water during the summer and dry months; it also allows us to continue to treat the storm water prior to recycling or discharging. In 2018, we saved 1.3 million gallons of water and achieved a 20 percent reduction in green waste.
In 2018 at our Draper, Utah, facility, we implemented a number of measures to reduce water usage to include xeriscaping and use of AstroTurf, projected to result in an annual reduction in water usage of one million gallons per year in 2019 as compared to the 2017 baseline.
