Details: The airport's interactive map holds 28 refill stations and flags 25 of them after security; its before-security flags are the Checkpoint 6 and ground transportation stations and, oddly, the one by Gates N8/N9. Bring an empty bottle through security using the liquid drains at every checkpoint, then refill it at a station. SEA sources its drinking water from Seattle Public Utilities, and EPA-required testing in 2023 and 2024 found no detection of contaminants, including PFAS and lithium. Customer Care: (206) 787-5388.
