Digital Realty Trust Inc. signed an agreement with Ecolab Inc. unit Nalco Water to advance water stewardship across its global data center portfolio.
As part of the agreement, Nalco Water will help deploy cooling technologies designed to balance water consumption, energy consumption and environmental effects at Digital Realty's data centers worldwide.
Digital Realty said its data centers used more than 1.4 billion gallons of water in 2018, 35% of which came from reclaimed, nonpotable sources.
The data center real estate investment trust has implemented water-free cooling systems across more than 344 MW of capacity since 2013, a move that it said is helping save approximately 1.03 billion gallons of water per year.
In a bid to advance the use of reclaimed water at its facilities in Santa Clara, Calif., the REIT said it recently completed the South Bay Water Recycling application. It expects the application to reduce its impact on the Silicon Valley potable watershed by 10 million gallons per year.
