Why we checked itSpecific quantitative claim about the effectiveness of closed loop water systems for data centers — verifiable against engineering and environmental data.
What we foundClosed loop systems can achieve 70–90% water savings in specific applications, but the range varies considerably by industry context — some authoritative sources cite lower figures (25–70%), while others cite higher figures (up to 98%) — making the specific 70–90% range a partial but imprecise characterization.
