Even best-in-class fab water programs face fragmented visibility, varying local conditions, and growing reuse demands. This presentation describes how Intel moved from managing water as a background utility to managing it like production, using an integrated water circularity management system built on operating envelopes and decision rules. In its first year at the facility level, the approach reduced freshwater withdrawal by 23% and site discharge by 49%, increased internal reuse, and delivered $3.2M in annualized savings with no reported production impact.
