Infomart Data Centers has announced it has completed construction on infrastructure necessary to utilize recycled water for cooling and landscape irrigation at its Silicon Valley data center. The Company's move to use non-potable, or "gray water," for 100 % of the mechanical infrastructure and irrigation surrounding the facility reduces costs and lowers its environmental impact.
Data centers have come under fire in recent years for the significant amount of water required to cool high-density server environments. According to one estimate, a 15 MW data center can use up to 360,000 gallons of water per day and drought conditions, such as in California, can exacerbate the delicate balance between a data center facility's water needs and limited resources.
Infomart Silicon Valley, the first multi-tenant data center to achieve LEED Gold certification in California, is again leading the industry in sustainability efforts with the conversion to recycled water. Because potable water is an increasingly endangered resource around the planet, Infomart made the investment to convert to gray water usage, which helps preserve regional potable water and aids the public utility by easing pressure on strained supplies.
"While water is necessary to keep our mission-critical data centers and server environments cool, the levels consumed by these facilities also place a great strain on water resources — especially in the drought-plagued Western U.S.," says John Sheputis, president of Infomart Data Centers. "Infomart's significant investment in the Silicon Valley recycled water conversion demonstrates our commitment to building energy-efficient, sustainable data centers."
The Infomart Silicon Valley recycled water system uses state-of-the-art water quality monitoring that provides advanced warning for operational issues caused by elevated water hardness, alkalinity or Total Suspended Solid (TSS) levels, while ensuring that no tainted water penetrates into the data center's mechanical infrastructure, where it can cause corrosion. Based on modeling exercises, with assumptions of 60% load and 60% gray water utilization, Infomart expects to save 800,000 to 1 million gallons of potable water per month.
"Our goal is to reach 100% gray water utilization, and we are working with the utility on these plans," adds Sheputis.
