Vantage Data Centers has standardized closed-loop chilled water cooling systems across its global portfolio, achieving documented water reductions of 90% compared to traditional cooling methods. Across three major U.S. projects — the Frontier mega-campus in Shackelford County, Texas; the Lighthouse campus in Port Washington, Wisconsin; and the Santa Clara III facility in California — Vantage deploys liquid cooling with closed-loop architectures that eliminate ongoing evaporative water consumption. For new facilities, the company has committed to water positivity: returning more water to local freshwater systems than the campus consumes in total operations. Vantage’s April 2026 technical blog post provides engineering specifics confirming that routine top-offs are not required under normal operating conditions.
