Louisiana data center water use — what the public records show

What's actually been filed

Times-Picayune reporting, citing state records, shows Meta's Hyperion data center will use an average of approximately 1.5 million gallons of water per day in baseline operation.

Separate state water-use authorizations reviewed by The Cenla Report indicate the same facility is authorized to use *up to* 23 million gallons of water per day — or roughly 8.4 billion gallons per year — under peak-conditions allowances.

Amazon has committed up to $400 million in regional water infrastructure investment alongside its Caddo + Bossier Parish campuses, plus a $250,000 community fund for STEM education and local water-quality projects.

Why operators chose Louisiana for cooling

Louisiana sits atop a network of alluvial aquifers (Mississippi, Red, Ouachita) and along multiple navigable river basins, which gives operators options that arid Sunbelt sites simply don't have.

River-adjacent siting in central and southeast Louisiana additionally opens the door to direct-river or river-adjacent cooling loops — a structural reason why Hut 8's River Bend and Applied Digital's central LA pipeline sit where they sit.

The publicly verifiable signals to watch

Parish water-board minutes and the Louisiana Department of Environmental Quality (LDEQ) discharge permits set the actual operating envelope.

Where a project is sourcing groundwater, the Capital Area Ground Water Conservation Commission and the Sparta Ground Water Conservation District filings are the official records.

Surface-water withdrawals are tracked through the LDEQ Water Permits Division.
