Two New WaterStars Shine

IRWD recently honored Hoag Hospital Irvine and Chapman University’s Rinker Health Education Campus as WaterStars – Certified Water-Efficient Businesses. Hoag installed low-flow fixtures and faucets and automatic flush valves, uses water-efficient instrument sterilization, and maintains low water use in its cooling towers and boilers. Hoag’s recycled-water drip irrigation system is activated by weather-based controllers. Combined indoor and outdoor conservation measures save Hoag more than five million gallons of water annually. The Rinker campus installed efficient fixtures, swapped turf for drought-tolerant plants, and upgraded to smart weather-based irrigation controllers. Savings: two million gallons per year, with more anticipated as remaining turf is replaced.
